Re: partial download of modis and viirs data

If you mean spatial extracts of scenes, then yes, you can request spatial extracts for your region of interest. For L1/2 data see: https://oceancolor.gsfc.nasa.gov/cgi/browse.pl For L3/4 data see: https://oceancolor.gsfc.nasa.gov/l3/ L3/4 data are also available via OPeNDAP if your client program su...

Question: Issues loading sample OCI file

Re: Issues loading sample OCI file

Can you specify the version of SeaDAS that you are using and the platform you are installing it on? --oci is the argument to the install_ocssw script that installs the OCI processing environment to your SeaDAS ocssw/ directory. --ocia, --ocip and --ocis are no longer supported by install_ocssw. SeaD...

Question: How MODIS processed climatology data

Re: How MODIS processed climatology data

We do not create temporal subsets of the climatology time series, we calculate only for the full mission. If you require a temporal subset, you will need to download the monthly files and calculate the means yourself using a program like SeaDAS.

Re: Issues loading sample OCI file

These were pre-launch proxies for OCI data. They are no longer supported. --ocia install PACE OCI AVIRIS files --ocip install PACE OCI PRISM files --ocis install PACE OCI Simulated data files That sample file link is bad and points to a pre-launch simulated L1B file. I'll talk with the page owners t...

Question: No new VIIRS SNPP since 20241103T054800
Replies: 1

Re: No new VIIRS SNPP since 20241103T054800

The SNPP GPS entered a degraded state at 20241102T221500 and VIIRS Ocean Color/SST processing was halted.

NOAA does not recommend using S-NPP Products from observations taken after 2215Z on November 2, 2024 for operational purposes.

A recovery attempt is scheduled for today 11/4.

Question: 2 Different Errors From Attempting to Open L2 netCDFs in SeaDAS

Re: 2 Different Errors From Attempting to Open L2 netCDFs in SeaDAS

You can try running 'ncdump -h' to see if they are valid netCDF and 'file' to see if the file is compressed without an extension to indicate it?

Question: Identifying PACE Rrs Wavelengths

Re: Identifying PACE Rrs Wavelengths

I don't use ENVI to process OCI, but it looks like you are limiting your display to the RGB bands ( red as 0.64 µm, green as 0.55 µm, and blue as 0.47 µm). Is there a True Color option that you have set?

Question: Error using ocssw calibration on VIIRS
Replies: 6

Re: Error using ocssw calibration on VIIRS

Yes, to make an L2 file you should provide the ancillary data. We make an L1B file from the L1A and GEO and then pass the L1B to l2gen.
I think l2gen has the code to make L2 directly from L1A and GEO but I will defer to one of our SeaDAS experts on running that...

Re: Error using ocssw calibration on VIIRS

Are you setting the correct environment?
export OCSSWROOT=path_to_your_ocssw_directory
export OCVARROOT=$OCSSWROOT/var

We stage the operational GEO files so you don't have to make them.
Replace "L1A" with "GEO" in the filename.
