local_planet error???

[alaroy]

Greetings Earth-data-lings!

We’re consistently getting an error when we try to process NPP L1A to L2 data using l2gen.
We’re trying to run a command of the following form:

Code: Select all

l2gen maskland=0 proc_cloud=0  maskcloud=on cloud_thresh=0.1  maskhilt=0 maskstlight=0 resolution=1000 gas_opt=8 l2prod=rhos_NNNN,rhos_MMMM,rhos_PPPP ifile=S20250414154200-L1A-NPP-OBPG.nc geofile=S20250414154200-GEO-NPP-OBPG.nc ofile=S20250414154200-L2-NPP-OBPG.nc.tmp

It always fails with a bunch of errors of the form:

Code: Select all

….
Allocated 4080040 bytes in L1 record.
Allocated 4080040 bytes in L1 record.

In case it helps we have l2gen version 9.10.0-V2025.0 (Jan 16 2025 23:07:44)

Thank you in advance for any pointers you can give me on this one. Hopefully I don’t have to change my local planet in order for it to work !
