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

install_ocssw --list_tags
to see the current available OCSSW tags.

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.

So now that VIIRS LUTs have changed and no longer work in the old stream, I need to update.

I see R2022.14 now, so should I be using this and not R2022.7 listed in the post or the R2022.12 mentioned in the email? Is it always the case that we need to chase the R updates prior to the operational V versions being released. How do we determine when to switch? Should I switch from a V version to a newer T or R version? If yes, should it be to a T or R versions?

I believe that we are on all the mailing lists, but don't see the roll outs of the T versions either?

For instance. are these 2 the same? If not, why not? And how can I tell by just glancing at the --list_tags ouput?
[oo_processing@optics1] $ ./install_ocssw --list_tags | grep 2022.12
R2022.12
T2022.12


It would be very helpful if a chart were developed that showed the dates that the versions were released.

[oo_processing@optics1] $ ./install_ocssw --list_tags | grep R2022
R2022.0
R2022.1
R2022.10
R2022.11
R2022.12
R2022.13
R2022.14
R2022.2
R2022.3
R2022.4
R2022.5
R2022.6
R2022.7
R2022.8
R2022.9

You can get the old LUTs back (see my response here: viewtopic.php?p=12674#p12674), but if you want to update, go with R2022.14. The 'R' series is the new 'V', and once we get through ALL the missions we're reprocessing, a new 'V' tag will be defined (which will be equivalent to the last R tag we make). At that point, the R-line will cease. You can ignore 'T' tags, those are just our development (i.e. 'test') tags - they eventually become 'V' (or 'R') tags.

Each series is incremented sequentially, we will go through a lot more Ts than Vs (or Rs).
The R tags are updated as we process each mission with the R2022 configuration.

Stay up with the highest numbered R tag for now (V tag once we get through the missions) and you'll have the latest.
If you look at https://oceandata.sci.gsfc.nasa.gov/manifest/tags/ you can see the date each tag was made...if that matters to you.

Sean
