Re: MODIS/AQUA "land" bands in R2022

Yes, the land bands received the same treatment as the ocean bands in R2022 :)

Question: Modis L1A Extract: Error Locating Pixel/Line Range
Replies: 2

Re: Modis L1A Extract: Error Locating Pixel/Line Range

The scene you specified does not cover the region of interest you are trying to extract:

https://oceancolor.gsfc.nasa.gov/cgi/browse.pl?file=A2002191103000.L1A_LAC

So...the code is correct in reporting that it cannot find the pixel/line range

Question: VIIRS level 2 processing error
Replies: 6

Re: VIIRS level 2 processing error

MODIS is not VIIRS.

Use the delivered binary for calibrate_viirs and convert the VIIRS L1A file into an L1B file. Use that L1B file in the l2gen process and it should work, e.g.:

Code: Select all

calibrate_viirs ifile=V2019216051800.L1A_SNPP.nc l1bfile_mod=V2019216051800.L1B_SNPP.nc

Re: VIIRS level 2 processing error

Did you recompile the binaries? The "VIIRS L1A reader is not implemented" message will not be reported for binaries that we distribute, but will result if you compile locally without the VIIRS shared libraries.

Re: MODIS Aqua reprocessing status 2022

The CMR records are complete for R2022. I just ran a query in search.earthdata.nasa.gov for 2003 using the bounding box you defined. It returns 1656 granules. Running a similar query in our L1/2 browser returns 1560. The 96 difference is likely the difference between geodetic (CMR polygon bounds) an...

Question: L2bin Prodtype 8-day
Replies: 3

Re: L2bin Prodtype 8-day

OK, a couple of things to note here. The l2bin options for sday/eday are only useful when binning global data and are unnecessary for a regional binning (even if that regional binning includes 8 days worth of source L2 data). Also, the prodtype option should be set to 'regional' if you are not tryin...

The striping and the lack of data are the same problem.

Re: modis r2022 par data problem

Robert, :shock: OK, that is definitely a problem - and seems to be related to the sea ice flagging, which is why it only shows up in PAR in the high latitudes (PAR masks on SEAICE at L2 - no other algorithm does so). Now that we know a) there is a problem and b) what the source of said problem is, w...

Re: OLCI Download from L1&2 Browser - no data visible

Hi Sam, Yes, the L1/2 browser is being cranky with displaying the global chlorophyll browse maps for OLCI - it does work for the pseudo true color (TC) maps, though :D It's a very stubborn problem and has to do with time (13, but sometimes 18, seconds in fact). ...which affects the way the browse im...
