Re: update_luts and gpt SeaDAS 8.4.1 on Centos 7

SeaDAS 8.4.1 defaults to the V2023.3 tag for the OCSSW software, which provides update_luts version 2.1. The python scripts are not OS dependent. Make sure you don't have a previously installed version that is being called. You can verify the installed version of OCSSW in the GUI (SeaDAS-Toolbox->In...

Re: OCSSW modis_GEO Ancillary Data Issues

Well, something buggered the sqlite DB used by the ancDB code. Perhaps something on the SQLite documentation page about possible sources for corruption will help you diagnose the issue: https://sqlite.org/howtocorrupt.html

Re: Download L3SMI data using R

The 10kb file is probably the HTML page for the login redirect. This means something isn't right with the way your credentials are passed, and you were not logged into your EDL account. Verify that your .netrc file is correctly defined.

Question: Incorrect File Size for Aqua, Terra and VIIRS SST and Chl files

Re: Incorrect File Size for Aqua, Terra and VIIRS SST and Chl files

Mike,

Both methods are pretty equal. The traffic is all over HTTPS, so "data in transit" is encrypted. The appkey obfuscates a bit more, as the username isn't required (although is derived on the server side, as the key is unique). Really, it's down to preference and ease of use.

Re: Incorrect File Size for Aqua, Terra and VIIRS SST and Chl files

Oh what a tangled web... :shock:

We have identified and corrected the issue that was causing the basic authentication of username/password to fail. All *should* be working again...

Please let us know if you're still having issues.

Re: Hyperspectral Rayleigh Corrected Radiance from PACE

Yes. The product is rhos (3D array, or rhos_vvv -VIS bands in 2D or rhos_nnn -all bands in 2D). One caveat is that the sample data have been updated and I *think* are incompatible with the version of l2gen you have. You can update to the T2023.30 tag for a version that will work. The official ("...

Re: Incorrect File Size for Aqua, Terra and VIIRS SST and Chl files

The obdaac_download script (available via https://oceancolor.gsfc.nasa.gov/data/download_methods/) is a python script that uses the .netrc file for authentication. It also can use the appkey approach. I've just reconfirmed that both methods work. How are you setting up your requests call (it should ...

Re: lonlat2pixline outputs incorrect pix/lin values

Andrew, This is not a lonlat2pixline issue, but rather an issue with the MERIS file. The geolocation is not correct, possibly related to the gap you pointed out. Below are two images created from a subset of the scene you reference. The first is the M13_radiance field, the second shows the same fiel...

Re: Observation of Symmetrical Stripes in Tropical Regions Using MODIS Aqua Satellite Data Mean

I don't want you to think your message was lost...just that it's a tricky one to evaluate. We need to better understand how you are treating the data. Can you provide a more complete dscription of your workflow? (BTW, when including code, use the code wrapper so the indentation is preserved - the bu...
