PACE RGB generation

by tsm00 » Mon Apr 15, 2024 8:16 am America/New_York

Greetings,

I have a PACE related Seadas 9.0 question/problem. I am trying to generate a RBG true-color image from a level-1b granule using Seadas 9.0, Tag T2024.16. I am on a macos 14.2.1, and have python 3.12 active.

First, the installer had a problem with loading luts - the 'install_ocssw' script was defaulting to python2.7, but only for the lut installation.

Secondly, when I tried running 'mapgen':

mapgen --ifile /Users/tim/Desktop/images/PACE/PACE_OCI.20240413T175156.L1B.nc --ofile /Users/tim/Desktop/images/PACE/testrgb --use_rgb

I got this strange error message with 'dshea' in the error. It was:

line 246 of /Users/dshea/ocssw/oel_hdf4/libbin/ncdfbin_utils.c: NetCDF: Variable not found

I don't have this directory, and I think 'dshea' is a programmer for NASA, as that name appears also at the top of the 'install_ocssw' script.

I think its a code bug, but there is something weird with the original python installer defaulting to 2.7, even though my window had python 3.12 active when I ran the installer.

Thanks!

Tim

try adding '--product_rgb=rhos_610,rhos_555,rhos_465' to your command.

Sorry that won't help:

I'll notify the SeaDAS folks

please send or look at your seadas_info:

From command line:
seadas_info

...or in GUI:
Menu > SeaDAS Toolbox > System and Software Info

Make sure the returned info acknowledges that oci is installed and that you are using tag T2024.16

If I add l3bprod=rhos_465,rhos_555,rhos_610 to the l2bin command, the binning completes without error.

We replicated the error, and it seems that l2bin bailed when l3bprod was not provided.

Since OCI is hyperspectral, with an undefined l3bprod, the l2bin file has 286 binned rhos bands from rhos_315 to rhos_2258.
