Re: Large shift in a MOD09GQ image

Brett,

The location is 39.502 N 57.8569 E . The projection is MODIS sinusoidal.

Images on other dates don't have this problem.

Large shift in a MOD09GQ image

For the 2010_07_01 MOD09GQ image, in both v6 and v61, there is a large shift relative to the basemap around 39.5E 57.8N See screenshot where the river Volga on the basemap is shifted relative to the image.

Re: CMR API response does not list all the Rrs band files

Tommy, So to revisit my other question, is it expected to not see in CMR some file names present on oceandata.sci.gsfc.nasa.go? Currently https://cmr.earthdata.nasa.gov/search/granules.json?collection_concept_id%5B%5D=C1442922862-OB_DAAC&page_size=1000&temporal%5B%5D=2002-07-03T00:00:00/2021...

CMR stopped updating?

Hi, I'm seeing no new MODIS and GPM entries in CMR, which makes me suspect it's a CMR issue rather than a problem with individual datasets. https://cmr.earthdata.nasa.gov/search/granules.json?collection_concept_id[]=C193529902-LPDAAC_ECS&page_size=1000&temporal[]=2021-10-20T00:00:00/2021-11-...

Re: CMR API response does not list all the Rrs band files

Hi Tommy, I'm still seeing delays, so I'm trying to understand your reply. What file extensions do Near Real Time, refined-ancillary QuickLook, and Refined files are expected to have? Currently https://cmr.earthdata.nasa.gov/search/granules.json?collection_concept_id[]=C1442922862-OB_DAAC&page_s...

revision_date vs 'updated' in CMR granule search?

Hi, To find the recent MODIS granules, I'm trying to use CMR searches to list all the MODIS granules for a dataset past a certain production date. This would be easiest if the results are sorted by the production date, but this does not seem to be trivial. I can use revision_date in temporal filters...
