Re: Difference between Band1 and Band2 in Grace data

Hi, Thank you for providing the full data long name. There are three data formats for the same dataset, including netCDF, GeoTIFF and ASCII. You can use the netCDF file to check the property of each data variable. The tiff file contains two layers, lwe_thickness (Band-1) and uncertainty (Band-2). Pl...

Re: Difference between Band1 and Band2 in Grace data

Hi,

Could you provide the dataset short/long name? It would be helpful if we know which GRACE dataset you are referring to.

Re: No granule identifier in GRACE CMR entries

The GranuleUR is the unique identifier for granules, like the ShortName for collections. We do recommend to use the GranuleUR vs ProducerGranuleId in CMR.

Question: What CRS for QGIS - Sea surface temperature

Re: What CRS for QGIS - Sea surface temperature

Hi,

The simple answer is to use WGS 84 (EPSG: 4326) CRS. The MODIS L3 SST is in netCDF format, and can be imported by using Add Layer function. Not sure if this answer your question. Please let us know if you have further questions.

Thanks,

Re: No granule identifier in GRACE CMR entries

Hi Simon,

The ProducerGranuleId matches GranuleUR in most cases. You may use GranuleUR instead if feasible.

Thanks,

Re: Subsetting MUR-JPL-L4-GLOB-v4.1 data?

Hi, The Earthdata OpeNDAP uses the DAP2 as default, which is not working for MUR SST dataset. You have to use the DAP4 version. To enable the DAP4, you need to modify the HTTP link, https://opendap.earthdata.nasa.gov/collections/C1996881146-POCLOUD/granules/20230105090000-JPL-L4_GHRSST-SSTfnd-MUR-GL...
