The L2 file names are derived from the start time of the data in the L1B granule, which is later than the start time in L1B file name Can you add logic in your script to search forward by incrementing the L1B time by 1 sec in the expected L2 file name and check until it finds a match or reaches a li...

There are times when the definitive ATTEPH files that get published are bad, and can't be processed.

When this happens we fall back to using the predicted ephemeris.

Which input files are you using?

You can find the source L1B files here:

Thanks for reporting the problem. There likely won't be a fix in place until Monday 10/7

From the usage message, mapgen is expecting --parfile PARFILE or -p PARFILE. It is not handling par=PARFILE.

We had some server problems that were causing the Error 500 that should be fixed now.
Can you try again.

Thanks

The CZCS L3b monthly products are showing in :
https://oceandata.sci.gsfc.nasa.gov/directdataaccess/Level-3%20Binned/CZCS/
and L3m in:
https://oceandata.sci.gsfc.nasa.gov/directdataaccess/Level-3%20Mapped/CZCS/1

It must have been a temporary glitch.

Tommy

can you provide an example, the time in L2 file names can be slightly different from the parent L1 names.

Thanks

ESA will republish files. I you look at the last date/time node in the file name, that is the create date. Where there is an overlap, use the file with the most recent create date.
