Re: How to quantify GRACE uncertainty?

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.

Why do I need GRACE Tellus Mascon Scale Factors?

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. ...

Re: Suitable Location for Bathymetry Data?

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) ...

Re: GRACE Global Groundwater Data

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/ ...
