Supporting database to the publication: Sensitivity to lakes, subsurface hydrology and glaciers mass changes of the quantum technology gravity gradients and time observations on satellite MOCAST+. Database of the gravity changes for glaciers, lakes and soil moisture for South America. Gravity changes for lakes in Tibet. The fields are provided in Spherical Harmonic coefficients, according to the ICGEM conventions (Ince et al., 2019). Each file reports the description of the database in the header. The files included are the following: 1)SH_Amazon_LP.gfc 2)SH_Amazon_Seasonal.gfc 3)SH_Orinoco_LP.gfc 4)SH_Orinoco_Seasonal.gfc 5)SH_Parana_LP.gfc 6)SH_Parana_Seasonal.gfc 7)SH_SA_glaciers_LP.gfc 8)SH_SA_lakes_LP.gfc 9)SH_SA_lakes_Seasonal.gfc 10)SH_Tibet_lakes_known_LP.gfc 11)SH_Tibet_lakes_unknown_LP.gfc Reference: Ince, E.S.; Barthelmes, F.; Reißland, S.; Elger, K.; Förste, C.; Flechtner, F.; Schuh, H.
