Question: HICO

Re: HICO

Ah, yes, that one would be hard to find without knowing exactly where it was... It *should* be linked from here: https://oceancolor.gsfc.nasa.gov/docs/rsr/rsr_tables/ but isn't yet. We began, but didn't finish, an update to that information. Hyperspectral sensors are tricky to display the way we've ...

Re: How to Get Reflectance Data for Lat/Lon?

John, The answer depends on your needs. If you need the highest resolution, you'll want to grab the Level 2 files and extract the data from them ( SeaDAS can help with the data extraction). You can order the L2 files that cover your region of interest from our L1/2 browser . If you are looking for t...

Re: Problems to untar file with MODIS PAR L3 images

Laura, The .netrc set up is only needed once (unless you change your password or delete the .netrc file) Since you are using python, I would recommend using the requests module to accomplish the file retrieval, rather than wget. You could also just grab the obdaac_download script (available from the...

Question: seadas update luts problem

Re: seadas update luts problem

Jay, This is a fun one...if you run update_luts with -vv you should see that the error is a status 304, which isn't really an error (server is just telling the client that the resource hasn't changed). While not an error, it seems to be tripping up the error catching in the script. If you delete $OC...

Re: IndexError: string index out of range

Just making sure you're on your toes ;) We're developing a new ancillary retrieval process that will have a slightly different API from the current one. To test this new process, we needed it exposed on the external server...but in the process a wire got crossed and the old interface was inadvertent...

Re: Question about Sentinel 3A data access

These Sentinel 3A (and 3B) L1B files are the same data as distributed by ESA and Eumetsat. Yes, we are planning to process these data to Level 2 and Level 3 using the NASA standard algorithms. We are finalizing the code and vicarious calibration now and expect to initiate the L2/3 processing within ...

Re: Blank Rrs L2 VIIRS Bands

That scene is at night, so no valid reflective solar band data to be had.
