Hi, Thank you for your patience with this. This bug essentially makes l2gen skip atmospheric correction on the granule in question. I would suppose, then, that it would affect other products, any that require atmospheric correction. It seems that this particular issue affects JPSS1 specifically, we ...

Hello,

I dug deeper into this issue and found a problem with one of the LUTs used in VIIRS calibration. We're working on a fix.

Hello, Thank you for bringing this to our attention. We've been looking into this issue and have found that it was a simple memory allocation error. I won't bore you with the details, so, put simply, using NSEW parameters caused a bug to rear its ugly head in MODIS' L1 reader. There is nothing requi...

Thank you for your patience with this. I've been stepping through a debugger and found that the L1 mask is different between the examples you showed. When converting the L1 data to L2, there is a guard against atmospheric correction if the L1 record is masked already. In the JPSS1 data in the region...

Thank you for that. I am looking through the source code and will get back to you when I have something of substance.

Hi Julien,

Would you mind posting the filenames used to generate those images?

Hello,

Perhaps these two links will be of help.

Best of luck!

Hi there! My first question is over your reasoning for processing L1B into L2 using SREFL. Earth Data already has L2 SREFL files , and you could download them through obdaac_download as well. After downloading an SREFL file, you could run mapgen on the command line with a --projection flag to indica...

Hi astrotheus, Are you able to open the files with ncdump -h? As in, `ncdump -h PACE_OCI.20240426T074015.L2.OC_AOP.V3_0.nc`. If that's possible, that may help. What I am hoping to see there is for the metadata you're looking for to exist there, and I think that would point to a bug in your Python. I...

I believe that these two websites will be of interest to you, the MODIS inland waters products, and the CyAN products.
