Yes, it appears from that error message that there was an authentication issue with your requests. However, I see in our logs that you successfully downloaded this file on June 21st...in fact, you did so 9 times...so...is this still an issue for you?

The l2gen program is a complicated beast, especially when non-standard processing options are involved. The mode option really isn't something that should be changed by user input. What you want to change is vcal_opt. That option will set the mode option appropriately...it uses the same values, so 1...

The SPEXone (and HARP2) spectral response function data can be downloaded from here: https://oceancolor.gsfc.nasa.gov/data/pace/characterization/ The response functions on the https://oceancolor.gsfc.nasa.gov/resources/docs/rsr_tables/ page are for sensors supported by our l2gen code that is used fo...

The CMR result is more correct. The subscription service uses a cartesian box of the NSWE extremes for a granule in the search. This can lead to false positives as the bounding box associated with a granule includes area outside the granule. The A2025141165500.L1A_LAC granule does not contain any da...

Very few processing flags are masked in l2gen process, but yes, clouds is one of them. If l2gen determines a pixel is cloudy, it is extremely unlikely that Rrs could be retrieved if the mask were disabled (which you can do by setting the parameter maskcloud=0). The instrument has to see the ocean to...

I've passed this along to the programming staff to take a look, though you may be correct that it is missing a cos(solz) in the equation

A 503 error indicates a server-side error, which may be intermittent. I was able to run your code (after editing it to restore proper indentation - in the future you can wrap the text in the "code" element - see the angle bracket icon above -to preserve indentation). I did have to comment ...

Andrei, Looking at the 30 March 2015 date, the "missing" granules were QC failed (determined to be of bad quality) because of a spacecraft maneuver to execute a lunar calibration. This affected 2 full 6 minute granules and partially affected 2 others, though we do set the QC failure status...

Already done, just not released

Andrew,

It's a wee little thing: l1bfile_mod instead of l1bfile_img
l2gen requires the moderate resolution bands (750m), and cannot run on the imagery resolution (375m). You can output both, if you like, just pass l2gen the MOD file.
