SeaDAS l2gen albedo issue

[alaroy]

We are upgrading from a very old version of SeaDas / ocssw to a new one and are experiencing some trouble.

When we call a command of the form

l2gen maskland=0 proc_cloud=on maskcloud=on cloud_thresh=0.1 maskhilt=0 maskstlight=0 resolution=1000 gas_opt=8 l2prod=rhos_XXX,rhos_YYY,rhos_ZZZ ifile=S20250117192500-L1B-MRA-OBPG.hdf geofile=S20250117192500-GEO-MRA-OBPG.hdf ofile=/data/NC/L2/FAI/2025-01-17/S20250117192500-FAI-L2-MRA-OBPG.nc.tmp

the old version (9.5.0-V2019.3) runs through to normal termination and returns an L2 file. However, the new version (9.10.0-V2025.0) exits with the following error:

/home/dshea/ocssw/src/l2gen/setanc.c, 882: Cloud processing, requires an input surface albedo (sfc_albedo=...)

We're running in a near real time environment and can't wait on outside atmospheric condition files. What was the old version using for cloud albedo data, pleaae?

In case it makes a difference we're processing MODISA and MODIST data using l2gen.

Thank you for any guidence you can supply on this!

Andrew,
proc_cloud doesn't mean what you think it means. It is used for deriving cloud microphysical products - and only works for PACE OCI. Set proc_cloud=0.

Sean - thank you, that worked perfectly!
