These data are available as an ArcInfo 16-bit floating point binary grid in Environmental Systems Research Institute (Esri) format. The grid consists of two folders, one with the "grid name", and one "info" folder. The two folders for each grid are compressed into one file using WinZip (ver. 14.0) software. To utilize these data, the user must have software capable of uncompressing the WinZip file and importing and viewing an Esri ArcRaster grid. The two folders for each grid must be uncompressed to the same folder. If during the process of extracting multiple grids in WinZip format to the same folder, the user is prompted by WinZip software to "overwrite existing files" in the info folder select the "yes" option because the same info folder is included in the other gridded datasets.
