Inventory files and Altitude levels
To make the HTTP requests more efficient, multiple levels are merged in a same file.
The agl/TMP file contains 1000m AGL, 2000m AGL...
The isobaric/TMP file contains 800hPa, 600hPa...
It is possible to do partial requests, to save bandwitdh and download only the levels you are interested in. We provide inventory files enabling you to do so.
To get the inventory files, replace .grib2 extension with .inv in the url.
See Partial download for usage instructions.
