IR profile data into Little R format conversion

[met-sree]

Dear all,
We intend to assimilate thermodynamic profiles (including temperature and water vapor data) extracted from Infrared sensors mounted on geostationary satellites like GOES, Himawari, INSAT, etc. Could you advise on the correct platform ID and observation type to use when converting this data into LittleR format? Your insights would be greatly appreciated.

Thankyou,
Sree.
