Hi,

Scale factors, measurement and leakage errors were shared in the previous release (Level 3, RL-05). However, these are not available in the current GRACE and GRACE-FO datasets. Has any information been shared on how to calculate the uncertainty in the TWS data?

Thanks a lot.

Using 3-degree mascons as a basis function acts as an inherent smoother on the data. Therefore, the GRACE/Tellus Project has derived a set of scale factors (what are also referred to as global gain factors) to aid in the interpretation of signals at sub-mascon resolution. ...

How can i know the passing time of the GRACE satellite over a location? Particularly in the following coordinates, latitudes 13.5,14.5,15.5 and longitudes 76.5,77.5,78.5

Thank you very much Wenhao. I appreciate the info. :D Hi Lewis, You could try to look at the JPL TELLUS GRACE-FO Level-3 Monthly Ocean Bottom Pressure Anomaly (https://podaac.jpl.nasa.gov/dataset/TELLUS_GRFO_L3_JPL_RL06_OCN_v03) and JPL Mascon (https://podaac.jpl.nasa.gov/dataset/TELLUS_GRAC-GRFO_MASCON_CRI_GRID_RL06_V2) ...

There is no official "GRACE Global Groundwater Data”. What one does is get the GRACE Total Terrestrial Water Storage Anomaly (TWSA). For example: https://podaac-opendap.jpl.nasa.gov/opendap/allData/tellus/L3/mascon/RL05/JPL/CRI/netcdf/ ...

Hi Samuel, Thanks for the nice note. To get to the heart of your question: we simply don’t measure absolute range with the K/Ka-Band ranging system. You can use this data to determine how the relative range of the two spacecraft changes over time, but keep in mind there is an absolute bias between t...

The PO.DAAC is pleased to announce that the complete historical data records of GRACE Level 2 Release 06 (RL06) datasets are available. The complete records include all available historical data from April 2002 to June 2017. The initial publications for the RL06 ...
