Difference between Band1 and Band2 in Grace data

[amirhatami]

When I open JPL Tellus Tiff file in Qgis, It shows two Band for me. Which one should I use to calculate TWS?

Hi,

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

Thanks,

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). Please let us know if you have any further questions.

Best Regards,
