Hi all,

ufo supports using RTTOV as an observation operator. I recall that it used a custom version of the code instead of the standard version from EUMETSAT, and the main reason for this was to provide ecbuild / CMake packaging support.

Is there any chance I can get access to the relevant JCSDA-internal repository? I’m already a licensed RTTOV user, and I’m looking to test the operator in JEDI.
