SeaDAS version and R2022

by melinfr » Tue May 31, 2022 5:23 am America/New_York

Dear Support,
planning to reprocess large volumes of data according to R2022, I am wondering if the current SeaDAS is consistent with that reprocessing. Presently I have SeaDAS 8.2 installed (with the V2022.0 option), but the default options still seems to indicate the use of the single-scattering epsilon for 'l2gen' and 'getanc' still returns NCEP/TOMS type of MET data. From the page about reprocessing R2022 (https://oceancolor.gsfc.nasa.gov/reprocessing/r2022/olci/) accessed from https://oceancolor.gsfc.nasa.gov/reprocessing/ , I understood that there is a switch to a multiple-scattering epsilon and the use of MERRA ancillary data (among other things). Is it just that I need to wait for a new release of SeaDAS (having a tentative date would be great for planning), or is it that I should use different set-up's in order to be consistent with R2022 ? Thanks a lot for any advice,
Best regards,
F.

The latest R tag is R2022.4. You can install it with SeaDAS 8.2.0. https://seadas.gsfc.nasa.gov/downloads/

As we reprocess more missions, we'll add more tags like R2022.5, R2022.6...

Dear Support,
thanks a lot for your answer. We've now switched to R2022.4. As reprocessing deals with one mission after the other, is there a page where this SeaDAS tag evolution can be followed, to avoid disturbing you ?
Thanks a lot !
Best, F.

You can do

Code: Select all

Hi - I'm trying to figure out which version of OCSSW I want to use. My understanding is the V tags are the operational versions and the T tags are test versions. From this thread, I'm gathering the R versions are for the various steps in the Reprocessing roll out. I see we're up to R2022.7, which I'm assuming is the most up-to-date i.e. more up-to-date than V2022.0?

Once the reprocessing is complete, does a new V version get made?

Yes, R2022.7 is more up-to-date than V2022.0. Once the reprocessing is complete, we will make a new V tag.
