The NCEPR2 and AURAOMI have been replaced with GMAO MERRA2 ancillary MET files. Update your code to use these instead.

The mission began in July 2002, so the July and August monthly climatologies begin in 2002:

We are no longer producing the O3_AURAOMI_24h.hdf
We have switched to using the O3 from the GMAO_FP data.

Tommy

We stopped producing the AURAOMI files and now use the modeled O3 in MERRA2 met files.

Does ncdump -h work?

Tommy

The GMAO_FP MET data are used for near real time processing and are not permanently archived. If you are processing an earlier time period, you should be using the MERRA2-derived refined MET files

Do you have access to https://doi.org/10.1117/12.2528881 ?

The LUTs are not tied to a particular tag. You want to run the update_luts program to get the latest LUTs for viirsn.

See https://seadas.gsfc.nasa.gov/help-8.3.0/processors/ProcessUpdateLuts.html

Upon further review, we have decided that the current JPSS1 VIIRS calibration remains valid and the refined processing out to 2023-09-01 is under way. JPSS2 calibration is still under review.
