Re: l3mapgen is extremely slow when generating 500 m daily mosaic over China region – any optimization suggestions?
At 500m you might be running into a cache size problem with l3mapgen writing NetCDF. Try running l3mapgen with "deflate=0". The file will be a lot bigger without compression, but this should speed up processing if the cache is the problem. You can always run h5repack on the file to compres...

Re: mismatch in ntime
MODIST lasted longer than one of the internal tables could handle.
Need to use T20025.16 or later. See:

Re: MODIS L2GEN error: "mismatch in ntime" when reading XCAL file xcal_modist_txc_oc_v4.9b_412.hdf
The problem is that we did not expect Terra to last this long... We only had space in the code for 300 date records and the current xcal file for modist (xcal_modist_txc_oc_v4.12b) has ndates = 307. The fix for this first appearers in T2025.16 so any tag after that should work. Sorry it is not in an...

Re: OCSSW Install Error - "unsupported Mac machine = x86_64"
NASA does not allow Intel Macs, since they are too old to support. I had to remove Mac Intel support on May 16 2025. The last tags with Intel support are: T2025.9 V2025.1 These tags or older willl work for you, but yo will need an old installer. Download these two files in the same dir: https://ocea...

Re: OCSSW install error on older Mac with Intel
I no longer have access to an Intel mac at NASA, so I had to discontinue the intel mac distributions
T2025.14 was the last tag with intel mac support. You will have to grab the install_ocssw and manifest.py from that tag to install on an intel mac.

Re: PACE OCI resolution question
Actually 4 pixels are aggregated in the across track direction. The aggregation is done on the spacecraft before the data is transmitted. We do not have enough bandwith to send all the data. There is no way to get the individual unaggregated data.

Re: Missing gas transmittance file for S2B MSI
we have not generated gas transmittance tables for MSI. Your command will work if you get rid of "gas_opt=32".

Re: Missing gas transmittance file for S2B MSI
Sorry about that. We do not have a gas transmittance table for MSI yet.
Just put this on the l2gen command line or par file.
gas_transmittance_file=none
