Novel 5-day Level-2B solutions

High-frequency (5-day) gridded Level-2B equivalent water height (EWH) solutions derived from GRACE(-FO) observations using an LGD-based formulation. These products focus on resolving sub-monthly mass variability.

Version 1.0 (Experimental)

TUD-L2B-5dayEWH-GRACEv1.0exp
Early-stage prototype of the GRACE-only 5-day solutions. Contains preliminary and experimental data and should be used with caution.

Version 2.0 (Coming Soon)

TUD-L2B-5dayEWH-GRACEv2
First official public release with improved handling of major outliers, reduced side-lobe effects from the LGD-only formulation, and a complete and comprehensive uncertainty product.

Uncertainty product of Monthly Level-2B solutions

Gridded uncertainty estimates accompanying monthly Level-2B EWH solutions. These products provide a complete characterization of GRACE(-FO) and post-processing model uncertainties.

Version 1.0

TUD-L2B-EWH_UNC-GRACE
Monthly Level-2B EWH solutions with the first comprehensive, complete, and ready-to-use uncertainty product.

Version 2.0

TUD-L2B-EWH_UNC-GRACEv2.0
Updated uncertainty solutions with leakage uncertainty and climatological fits.

Version 3.0

TUD-L2B-EWH_UNC-GRACEv3
Updated dataset with SLR-free dataset and climatological fit uncertainties.

Version 4.0 (NEW!)

TUD-L2B-EWH_UNC-GRACEv4
Fully end-to-end user-friendly dataset. Addition of fully corrected (L2A->L2B) variable "ewh_mean_corr", CLIM_CORR data product with additional variables: "ewh_mean_clim", and "ewh_mean_tides" both being gridded time series with dimensions: (time, lat, lon).
