Monthly SSA-gapfilled and climSSA-gapfilled data based on CSR GRACE and GRACE-FO RL06 Mascons since 2002

Data infomation:We proposed a climate adjustment scheme using the Singular Spectrum Analysis (climSSA). The climSSA method was applied to reconstruct the 33-month gaps within GRACE and GRACE-FO missions, with the drought index data SPEI-6 derived from ERA5 as input to adjust the TWSA timeseries before performing the SSA gap-filling iteration process. We produced the SSA-filled and the climSSA-filled monthly equivalent liquid water thickness (lwe_thickness, unit in cm) GRACE/GRACE-FO products at 0.25°×0.25° over 2002/04-202605 and at 0.5°×0.5° over 2002-2022.
