Question 3. How Do I Know Which Spill Listed In The Left Section Of The Map Window Corresponds To Which Particular Spill On The Map?

Answer :

A function brought to GNOME 1.2.6 gives some assist with this trouble. Beginning with this model, whilst you create a spill, you can call the spill in the dialog box. Then, in the left section of the Spill Information window, the spill name will report the details of your spill (pollutant kind, quantity launched, launch time and function, and mass balance). We are nonetheless working on a feature to help you suit every spill call within the left segment with its corresponding spill on the map.

Question 4. Can You Provide Some Documentation On The Gnome Methodology?

Answer :

Technical documentation for GNOME has been up to date.

Python Tutorial
Question five. Has The Gnome Model Been Verified?

Answer :

The GNOME version is used in all NOAA Emergency Response Division (ERD) spill responses that require modeling. The model's algorithms function flawlessly, but the user is the important thing to putting in the version in Diagnostic Mode for spill response. Because the primary forces that circulate the oil (wind, currents, etc.) are not generated by way of GNOME, but enter through the consumer, the person is in the long run chargeable for the results.

During spill reaction at NOAA ERD, the trajectory analyst selects the physics she believes are maximum suitable for the spill and units up the model as a consequence. She selects the right hydrodynamic model for the currents, simulating tides and hydrology as essential, obtains a wind forecast from the NOAA National Weather Service, and estimates different parameters from reviewed literature and revel in. Once the version is set up, a prediction is made and later as compared with overflight facts from on scene.

If the contemporary and wind predictions are accurate, and if the windage and diffusion parameters are set correctly in GNOME, then GNOME will generate excellent trajectories. A forty eight-hour prediction of in which the oil will pass may be predicted to be within 1-2 miles. If the version and observations differ, hindcast version runs are made to song the model to the local situations before the following forecast is made. The forecast winds and currents are normally now not correct enough to generate trajectories inside 1 mile of accuracy after forty eight hours. This is why GNOME supports consumer-precise uncertainty bounds, which might be set in step with the uncertainty inside the input data. This is also why the GNOME input records is continuously up to date all through an occasion, and the model is rerun at the least once a day all through a spill.

Making predictions in tidally dominated areas is an awful lot simpler than in eddy-wealthy offshore environments. The availability of nearby real-time data and excellent wind forecasts (from the NOAA National Weather Service) are key to excellent spill trajectory estimates.

GNOME's Location Files are tuned to simulate local climatological conditions to the pleasant of our know-how. Though tides are predictable, other environmental conditions aren't so simple. Location Files aren't appropriate for spill reaction, simply as an almanac is not appropriate to are expecting the weather for a particular day.

Linux Interview Questions
Question 6. How Does Gnome Relate To Tap (trajectory Analysis Planner)?

Answer :

GNOME is our trajectory version and TAP is our Trajectory Analysis Planner. What's the difference? GNOME runs unmarried trajectories. If GNOME is run thousands of instances (the use of historical winds, tides, and currents), you may use TAP to investigate all the ones trajectories and calculate information from them.

TAP offers the probability of oil motion by way of searching at those thousands of trajectories. These chances allow planners to take a look at "what if" situations primarily based at the local oceanography and climate. Decision-makers can use TAP to decide whether to shop for greater growth or any other skimmer, or wherein to website a lightering place.

TAP cannot be used within the event of a actual spill. The state of affairs on a particular day might not be nicely represented inside the statistics, because spills frequently show up because of unusual instances. In the case of a actual spill, GNOME can be quickly installation to symbolize the environmental conditions of the spill. TAP is fine used for planning, while it isn't acknowledged what conditions may be while a spill happens.

Question 7. How Do I Get Gnome Analyst?

Answer :

GNOME Analyst is a NOAA ERD application that converts the number and role data for "excellent estimate" splots into oil density contours and converts the area facts for "minimal regret" splots into an uncertainty bounding contour. GNOME Analyst is utilized in-house and is not presently to be had for down load. We are, however, working on software to update GNOME Analyst, and it'll be publicly to be had when it is entire.

Question 8. What's The Difference Between Gnome And Ossm (on-scene Spill Model)?

Answer :

You would possibly call OSSM (b. June 3, 1979) the father of GNOME. OSSM become the first trajectory model developed at NOAA ERD, and turned into written as a command line Fortran code utility. GNOME was advanced next and became first released March sixteen, 1999. GNOME is written in C++, which turned into selected for 2 motives: (1) the addition of a graphical person interface to resource ERD responders and out of doors customers in quick setting up models, and (2) the support of gadgets in C++, allowing nifty capabilities in Diagnostic Mode.

Question nine. Why Do The Evaporation Estimates For Gnome And Adios Differ, And Which One Should I Use?

Answer :

GNOME makes use of a simplistic 3-segment evaporation set of rules, that is suitable for easy drills and educative comparisons. The oil weathering model, ADIOS (Automated Data Inquiry for Oil Spills), has the better evaporation and oil destiny estimates in comparison to GNOME. ADIOS additionally has an intensive oil library.

We've corrected some of insects in earlier versions of GNOME. Please ship reports of any troubles or bugs you stumble upon to the GNOME Wizard.

Here is a list of great insects in in advance variations of GNOME:

Earlier Windows variations of GNOME have been missing the windage button within the overflight conversation. Fixed 02/18/07.
Earlier Windows versions of GNOME had a worm affecting customers who have been uploading NetCDF currents or winds. The base time cannot be in advance than January 1, 1970 00:00 GMT, in any other case the Windows characteristic localtime() returns an errors and GNOME defaults the base time to January 1, 1970 00:00 GMT. GNOME still hundreds the document but the instances are all off. We added an alert for destiny variations of GNOME. Fixed 01/06.
Earlier versions of GNOME allowed customers to output MOSS documents for GIS structures with the Minimum Regret (Uncertainty) answer grew to become off; however, the GIS tool requires that Uncertainty be became on for the run. We delivered blunders checking with a message to alert users to turn on the Uncertainty solution and re-run the scenario before outputting GIS documents. Fixed 12/05.
Earlier versions of the Santa Barbara Channel Location File for Windows had a trojan horse in Diagnostic Mode. Opening the map dialog could purpose an errors due to conflicting messages from the Wizard command report. (Mac document did not have this trouble). Fixed 08/05.
Earlier versions of GNOME had a hassle with multiple access conversation boxes in Location Files. These versions could spotlight the closing entry container, which changed into complicated to the person. The new version highlights the primary access field. Fixed 06/04 with GNOME 1.2.5.
Earlier installers did not paintings well for Windows XP. Fixed 05/03 with GNOME 1.2.Three.
GNOME Diagnostic Mode customers couldn't open current .Sav documents from previous versions of GNOME. Fixed 10/02 with GNOME 1.2.2.
The Mac model of the Santa Barbara Channel Location File had a malicious program that made the currents go a little faster than they should. Fixed 10/02.
Earlier variations of GNOME set the age of spilled pollutant incorrectly. Fixed 11/00.
Earlier versions of GNOME allowed oil to "leap" over land, and did not nicely initialize oil age for oil weathering. Fixed 6/00.
Versions of GNOME in advance than v. 1.1.1 did no longer show the wind fields while you went thru the Location File a 2nd time.
GNOME versions 1.1 and later were corrected to examine Location File Save (.Lfs) documents made in GNOME 1.Zero for an evaporation-associated malicious program.
Windows versions of GNOME earlier than v. 1.1 incorrectly displayed years after 1999 in the map window list.
The GIS output from versions of GNOME earlier than v. 1.1 had a sign error inside the output longitudes, causing the data to be study in and located within the opposite hemisphere.
Earlier variations of the Prince William Sound Location File for Windows have been missing a few heritage drift records (Mac report did no longer have this trouble). Fixed 10/five/99.
In in advance versions of the Central Long Island Sound Location File, the tidal reference document turned into not correct. Fixed 6/eight/ninety nine.
In in advance variations of the Columbia River Estuary Location File, river scaling become no longer scaling river shipping. Fixed 6/1/ninety nine.
In earlier versions of the Prince William Sound Location File, uncertainty horizontal mixing become too high. Fixed 6/2/ninety nine.
Versions of the Prince William Sound Location File preceding to 4/2/ninety nine have been lacking the detailed assist subjects for using GNOME.
Question 15. (mac Only) Some Of The Dialog Boxes Are Too Big To Fit On My Display. I Can't Seem To Cancel Out Of Them Easily. What Should I Do?

Answer :

The Mac model is about for a display decision of greater than 640 * 480 on a 15-inch screen. If your decision and screen length do not will let you see the complete dialog field, you could circulate it so that you can see the bottom. Ordinarily whilst you clutch a conversation box with the cursor, you can not move it a ways sufficient as much as make the top bar move out of view. Here's the trick: If you very cautiously grab it with the cursor at the very outer facet part, you could them pass it up as excessive on your display's actual property as you would really like. You may additionally want to change your monitor's resolution to some thing higher.

Question 19. How Do I Open Gnome's Diagnostic Mode?

Answer :

To alternate to Diagnostic Mode, from the File menu, pick out Preferences. In the Preferences window, click on the Mode tab then, beneath Model Mode, pick out Diagnostic. (If you need to work predominantly in Diagnostic Mode, you may instruct GNOME to open in that mode whenever it starts up. On the proper side of the Preferences window, below Startup Model Mode, pick out Diagnostic.) When you exchange to Diagnostic Mode, GNOME will provide you with a warning which you are converting to a mode that calls for specific knowledge of trajectory modeling and could suggest which you first shop your Location File settings.

Question 20. What Do I Need To Make My Own Location File Or Diagnostic Save File?

Answer :

Most humans make their personal Diagnostic Save Files. Unless you intend to market a Location File, you could put all the equal physics in a Save File without having to assemble the Wizard professional system or the conversation bins. We've created a web page, Setting Up GNOME for Your Region, to guide you through this manner.

Gnuplot Interview Questions
Question 21. Can I Use My Own Currents Or Winds In Diagnostic Mode?

Answer :

Yes, you can import maps, currents, estimates of eddy blending, and winds into GNOME. Currents may be imported from any model that uses a square, curvilinear, or triangular grid. GNOME can use wind statistics from a time collection at a point, or a wind version on a rectangular or curvilinear grid.

You might also need to check out GOODS, an internet device that allows GNOME customers get entry to publicly available ocean currents, winds, and base maps from numerous fashions and facts sources. You can then down load the files in a format that may be study at once into GNOME (e.G., modern-day and wind documents in netCDF; map documents in BNA layout).

Question 22. Where Can I Get Currents And Winds For My Area?

Answer :

You can reap currents and winds from several resources, relying in your vicinity of hobby. We've created the web tool, GOODS, that enables you get entry to publicly to be had ocean currents and winds from various models and statistics sources. You can then down load the documents as netCDF documents that can be read without delay into GNOME.

To download currents, choose one of the Sea Surface Height and Geostrophic Currents datasets (06. Monthly; 14. Weekly; or 15. Near Real-Time Weekly). Check the container for "Sea-Surface Height + Geostrophic Currents," then click on Next. In the Select View field, select your favored view. In the Select Output box, select NetCDF file. In the Select Region box, pick your place of interest. Click Next. A document referred to as "LASoutput.Nc" will download.

To download winds, choose one of the QuikSCAT Ocean Surface Winds datasets (07. Monthly; 16. Weekly; or 20. Three-Day). Check the box for "Wind Speed + Wind Speed Vectors," then click Next. In the Select View field, pick your favored view. In the Select Output box, choose NetCDF document. In the Select Region container, select your region of interest. Click Next. A document referred to as "LASoutput.Nc" will download.

Another source you may want to test is Ocean Watch: Central Pacific, one in all numerous sources of present day/wind information. On the Ocean Watch web site, pick out the option, "Live Access Server (LAS) for Satellite Imagery and Data."

Question 23. Where Can I Get Digital Shoreline Data Easily?

Answer :

The USGS Coastline Extractor is a source of detailed shoreline data for the U.S. And the arena. You can use those facts documents in GNOME, however you'll need to modify them to comply with BNA format. We've created a web device known as GOODS that will help you translate the digital coastline facts to BNA format.

The Coastline Extractor web page also makes river places and political barriers available; but, you must check that any political obstacles on your place of hobby are updated.

UNIX Memory Management Interview Questions
Question 24. Will I Ever Be Allowed To "paint" In My Current Vectors?

Answer :

No. Algorithms that "unfold" velocities among observations with the aid of easy smoothing operations do not preserve mass or water, in our experience. We require hydrodynamic model output for currents so that the present day fields replicate the physics the person intends: mass conservation, Coriolis consequences, geostrophic stability, Ekman dynamics, etc.

UNIX/XENIX Interview Questions
Question 25. What Are The Arrows On The Map?

Answer :

Arrows indicate (1) speed vectors if "Show velocities" is chosen on one of the current styles or (2) movement distance in one timestep if "Show Currents" is selected below Model Settings.

Question 26. Why Do The Movement Arrows Look Strange?

Answer :

Try turning off or cutting down the Random diffusion. Depending at the currents, the diffusion can add a little randomness to the sample or completely dominate it. The Windage placing within the Variable Winds window may motive this. Normal values of windage are 1-four percentage.

Advanced C++ Interview Questions
Question 27. Why Are The Arrows So Far Apart?

Answer :

We'd guess you are looking on the Movement grid with the zoom set a long way out. Try zooming in on a place of interest, and the arrows have to appearance better (nearer together in absolute distance). The spacing of the arrows for the motion grid is calculated on the map window length; the size of the arrows is calculated on map scale. Zooming in will growth the dimensions of the arrows and their apparent spacing.
