Question: l2gen on landsat 8 collection 2

Re: l2gen on landsat 8 collection 2

The code is reading band 9, but it does not treat the band as it does other TOA data. It is read directly into a record specifically assigned to rho_cirrus. This is done because the cirrus channel cannot be treated the same as the other TOA bands. If you want to see the output from l2gen, you will n...

Question: Ancillary data not available
Replies: 3

Re: Ancillary data not available

The l2gen code has supported these ancillary files since 2018, but we've also modified what we were storing in the MET file since the original implementation. A safe bet is V2019.3 (which was supported by SeaDAS 7.5.3), as that is the tag that supported the last SST reprocessing (which required the ...

Re: SDP Toolkit Installation Error in SeaDAS 8.2.0 Build from source code

Well, that's likely the problem. The installer scripts that comes with the SDTPK package were written for the CSH shell (thus it is listed as a requirement for building OCSSW - see https://seadas.gsfc.nasa.gov/build_ocssw/). Without it, your system will not be able to build the toolkit. Try installi...

Question: Subsetting MODIS-AQUA download by lat/lon with wget?

Re: Subsetting MODIS-AQUA download by lat/lon with wget?

If properly escaped, the command may work (I've not tried it), but it will only return a list of files that match the region of interest - it will NOT result in a downloading of data subset to the region of interest. CMR only provides search capabilities. See my previous reply about extraction.

Re: MODIS Aqua SST data citation and documentation

The OBPG is the processing center and while we do distribute the data, the PO.DAAC is the archive center. Here's a link to the PO.DAAC page on the MODIS-Aqua 9km product (which has a tab for citation :D ) https://podaac.jpl.nasa.gov/dataset/MODIS_AQUA_L3_SST_THERMAL_MONTHLY_9KM_DAYTIME_V2019.0 Regar...

Currently, the source code for the science data processors is available publicly only through the install_ocssw package distributed with SeaDAS. Visit https://seadas.gsfc.nasa.gov/downloads/ and scroll down to "Manual installation". (it can also be installed via the GUI...) We are working ...

Re: Subsetting MODIS-AQUA download by lat/lon with wget?

Anthony, We also support extracted subscriptions, but currently only or L1 and L2. It is our plan to extend that support to L3. Another plan in the works is to have the file search API support spatial searches (currently it only does temporal) and allow it to submit extraction requests. ...that migh...

Re: Subsetting MODIS-AQUA download by lat/lon with wget?

Anthony, That example is to an existing extracted L1A file (one used by our SeaBASS team for doing validation analyses). We do not support extracting on the fly, but do offer extraction via data orders for L1, L2 and L3 data. Using the L3 browser, you can request spatially extracted data to be stage...

Re: Error finding SeaHawk products

The file you listed (and likely the 13 others you found) were flagged for bad quality, but after the CMR record was generated. The ocean color L1/2 browser and our download tools knows about this flag and so stubbornly refuse to show the file. The CMR records have been scheduled to be removed (there...

Re: Question about using wget on for Aqua and Merra2

Whether or not I use the password credentials in the wget command, the result is a file with the .nc extension: Yes. The wget program has no idea what filetype is being sent, just that you requested some file (with a .nc extension) and some data was sent to you (so it saved it to a file with the na...
