Limitation of reff
There are different limitations on the reff that might need to be adapted for the usage with RTTOV:
REAL(wp), PARAMETER :: reff_max_qc = 30.0e-6_wp ! Maximum reff cloud water in tables from RRTM
REAL(wp), PARAMETER :: reff_max_qi = 99.0e-6_wp ! Maximum reff ice in ECCRAD. It Crashes for larger values
! REAL(wp), PARAMETER :: reff_max_qi = 120.0e-6 ! Maximum reff ice in tables from RRTM
(code)
RTTOV mentions the following limitations of effective diameter in their manual:
- ice: 10-120µm
- liquid: 2-52µm
This would mean that first, we also need to implement a lower limit and second the current maxima are too high.
It is unclear, if RTTOV fails for larger radii or does its own adaptation.
