Hi Gilbert & Everyone,
I see what you see (and don't see). It looks like the level2 GLMISatSS
(gridded) GLM data is still flowing but not level3, see below.
The difference between the level2 and level3 GLMISatSS data sets is
temporal aggregation; level2 is one minute while level3 is five minute.
Interesting that we lost one but not the other, especially since the five
minute set is more used. Did an IDD script die someplace? I can't recall
where/how this data is generated/fed...
If it is just gone you have a couple options. Since we still have the
level2 data you can aggregate that yourself. You can also compile this
product yourself starting from raw GLM tiles, if you want to go that route
I'm including some references below to help you do that. TL;DR: you stitch
raw tiles together into the level2 product using glm-restitch, and then
each time you make a new one you aggregate that and the last four to make a
level3 set. And see, that's why I wonder if a script just crashed
someplace because that tiled and level2 data is still there and I thought
this was Unidata's processing flow too... but it's been a minute and I'm
probably wrong.
Best,
-Mike
