Question: Harmony spatial subsetter does not work

Re: Harmony spatial subsetter does not work

Mati,

What data products were you trying to extract? We are aware of an issue with older data from some collections for which the subsetter doesn't work properly (though newer data from those collection does work...)

Re: MODIS Aqua download problems

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?

Question: l2gen failed with exit code 139

Re: l2gen failed with exit code 139

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...

Re: Where to find PACE SPEXone Spectral Response Functions

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...

Question: Inconsistencies between CMR and OBPG subscription
Replies: 2

Re: Inconsistencies between CMR and OBPG subscription

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...

Question: l2gen Rrs in cloud pixels
Replies: 1

Re: l2gen Rrs in cloud pixels

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...

Re: The issue of l2gen processing Landsat 5 6

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 ...

Re: Changes in VIIRS SNPP L1A data

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...
