Known bugs and issues
Please report any bugs you find in RTTOV using the NWP SAF Helpdesk.

Bugs/updates in earlier versions have been fixed/implemented in later versions.
Date Type/Status Description
27/02/2025 Minor bug - fixed Affects: solar simulations when passing multiple profiles into RTTOV and one or more (but not all) profile solar zenith angles exceed the maximum allowed value (85.3 degrees) (RTTOV v14.0).
Issue: it is possible that some radiance outputs (it has only been observed in overcast radiances so far) contain spurious values for VIS/NIR channels corresponding to the profiles with solar zenith angles larger than the maximum. All outputs should be zero for such channels.
Fix: download and extract this tarball to the src/main/ directory, and recompile RTTOV (a clean compilation is not necessary).
