Extract Levels and Variables You may select some or all levels and variables. The selections below represent common choices which may or may not be relevant to the files that you have selected. For example choosing RH (relative humidity) would be pointless in file of sea-surface temperatures. In addition, not all possibilities are allowed. For example, suppose you only want the virtual temperature at the tropopause at 01Z. In this case you'd have to transfer the entire file.
For GRIB-2 data only.
Select the levels desired: all 10 m above ground 2 m above ground cloud ceiling entire atmosphere (considered as a single layer) surface
Select the variables desired: all CEIL DPT GUST HGT PRES SPFH TCDC TMP UGRD VGRD VIS WDIR WIND
File transfer times can be reduced by only transferring a subregion. You can use this section to extract a geographic subsection from a most GRIB files. Use negative numbers for south and west.
