The TRY is composed of 12 separate months of data each. TRYs files are used to do compliance analysis for UK Building Regulations: TRY. The weather variables are synthesised into 2 types of CIBSE weather files: - Design Summer Year (DSY) - Test Reference Year (TRY) DSYs and TRYs are used as climate inputs into building simulation software.

There are three versions of the TMY weather files that can be downloaded. If the user wishes to use the weather file for their eQUEST simulation analysis, they can click on theMeteonorm EPW weather data output for Honolulu International airport. This will initiate a download of the DOE-2 file created by a Revit-based product and GBS to provide the information on this screen. Click on the DOE-2 file link. Download the library file (BDLLIB.dat) from Daikin AC website.Tutorial: Using NDFD gridded data in a GIS Environment (Shapefiles and Floating Point Grids)and weather files that were used by GBS. VRV library file into eQUEST: 1.

Each 5km grid cell has forecast information so that a point specific forecast can be generated for any cell based on geographic coordinate location. Virgin Islands, and Puerto Rico. And separate grids that cover Hawaii, Alaska, the U.S. The database is based on a 5km national grid that covers the Continental U.S.

Using NDFD grids for pre-Hurricane landfall decision makingDuring the 2004 hurricane season NDFD forecast elements were used to display experimental forecast elements such as wind speed, wave heights, and quantitative precipitation forecasts along with hurricane forecast tracks in a map format that was used by DHS/FEMA for risk analysis at the FEMA Region IV Regional Operation Center and Disaster Field Office. The best way to illustrate the power of using NDFD grids in a GIS can best be presented via a use case scenario given below. Using the NDFD data in a GIS gives the flexibility to deal with either Raster versions of the NDFD grids (floating point grids), or vector versions (ESRI shapefiles) as well as other formats that are just recently becoming importable into GIS like NetCDF files and GRADS. This is the case for marine interests as well, as the NDFD grid extend offshore several miles and deliver wave and wind information. The result is essentially a real-time and forecast decision support tool for making critical decisions based on various weather elements. Bringing the NDFD gridded files into a GIS enables the user to not only display the forecast elements with other georectified datasets such as satellite imagery, aerial photographs, and planimetric layers such as political boundaries, road networks, buildings, etc…, but also to query the data and use it for geospatial analysis.

In the graphical user interface (GUI) tkdegrib, click on the Download tab. See Figure 1 and 2 below.Figure 1: Forecast wave height along the shore of the Gulf of Mexico during Hurricane Ivan.Figure 2: Forecast wind speed along the shore of the Gulf of Mexico during Hurricane Ivan. This is an example of how having the NDFD grids converted to GIS significantly benefited the decision making process for weather driven natural disasters such as hurricanes. These maps were used to create the Presidential Briefing Package in which DHS/FEMA briefs the executive branch on potential damages that will be incurred from the approaching storm so as to pre-secure federal resources for response and aid through a presidential disaster declaration. The elements gave DHD/FEMA risk analysts an idea of the spatial coverage and intensity of forecast winds and wave heights.

Once the downloading begins, there will be an indication in the Message Window that it is working. After all the selected data are highlighted, click on either the Download by ftp button or the Download by http button (either will work) at the bottom of the window (Figure 3). Data for each weather element can be downloaded by highlighting the sector file, or individual weather elements can be downloaded by holding down the Control key on the keyboard and highlighting one or more elements.

When the data are finished downloading, click on the GIS tab. Convert the data to an ESRI shapefile Only the needed weather elements are highlighted, rather than the entire sector, and the user is about to click on the Download by http button. Note: The progress bar will say 100 percent before any downloading has taken place.Figure 3: In this example, the user needs data from specific weather elements within the Pacific Northwest sector.

The shapefile this user wants to create is the temperature of the Pacific Northwest on at 12:00 a.m., which is 8 hours from the time the weather was forecasted.E. The temp (temperature) file has been expanded and a data set is highlighted in the inventory chart. NDFD Tkdegrib and GRIB2 Data Download Tutorial (PDF).Figure 4: In this example pacwest (Pacific Northwest) sector is expanded. A similar document is also available in a portable document format. Select the data set in the inventory chart to be converted to a shapefile (Figure 4).Note: For more information on the inventory chart, see the Degrib: Man Pages and Full Tutorial. Double-click on a specific weather element in the top right corner, and it should fill out the inventory chart below.

In the example above the temperature data (_t) is from the Pacific Northwest sector (pacnwest). The generated shapefile will be in the corresponding sector folder. Inside that folder is a folder for each of the sectors. Manually type the output file name into the OUTPUT Filename dialog box or click the Recommend button to have tkdegrib choose one (Figure 6).Figure 6: When tkdegrib recommends a file it stores it on the local drive in the ndfd/degrib16/output folder.

A non-verbose shapefile will generate point identification and data, but not the latitude, longitude, and X and Y (Figure 7). Shp file if the values for latitude, longitude, and X and Y are needed. Check the box for Verbose. Shp file (Point, Small Polygon, or Large Polygon).Note: For more information on types of shapefiles download the NDFD Tkdegrib and GRIB2 Data Download Tutorial (PDF).H.

Import an ESRI shapefile into ArcGIS: Shp file button at the bottom center of the window. The Earth Axis options are for more advanced options.J. Most of the weather elements will default as 0 the exceptions are snow and waveh, which will default as 1, and qpf, which will default as 2.Figure 8: Depending on preference, the default values can be accepted for Round data to and Units.

Click the Add button.D.The shapefile will now appear in the Display view on the left side of the window, and the Map view will appear in the right side of the window. Navigate to the shapefile and highlight the shapefile. Highlight the file and click the ADD button (Figure 9).Figure 9: In this example, a shapefile for temperature in the Pacific Northwest sector was generated and placed in the pacnwest folder.

Click on the Import button in the top left corner (Figure 11).Figure 11: In the example above, the Symbology tab is selected and the user is going to import a standard legend into ArcMap.D. In the Layer Properties dialog, click on the Symbology tab. Double-click on the shapefile in the Display view (or right-click and scroll down to Properties) of ArcMap. Load Legends into ArcMap to view GRIB2-derived shapefiles: When a shapefile is imported into ArcMap, the symbology is defaulted as one symbol and one color.4. The data represent the temperature (_t) of the Pacific Northwest (pacnwest) sector for at 12:00 a.m.

Select the /point_legend or /poly_legend, depending on which type of shapefile was generated, and highlight the individual weather element that the shapefile addresses. Navigate to the /ndfd/degrib16/arcview/ folder.F.
