Re: tag=R2022.19 OCSSW SMI longitude_step differs from latitude step
Thanks George, I'll look into it. I will also fix the benchmark scripts to deal with the new naming convention.

Re: How to reproject MODIS L2 data via Python?
You have found the MODIS Bowtie effect. Since the MODIS sensor has 10 detectors that take data on each scan, the position of the edge pixels at the beginning and end of the scan overlap the previous and next scan. Here is a web page describing this in more detail: https://oceancolor.gsfc.nasa.gov/do...

Re: ATMFAIL on northernmost 3 lines in OLCI granules
I found the problem with the SAFE file format reader. This will be fixed in the next T and R tags. A value needed by the smile correction was not calculated soon enough. Thanks for finding this.

Re: “msis2a_gas_transmittance.nc” is missing for OCSSW
MSI does not work with the "R" tags or any "T" tag > T2022.13
I would suggest you use the standard tag for MSI (V2022.0)
We will look into updating the MSI processing.
