Remarks
GFZ operates the IGETS data base of worldwide high precision SG records. The hosted products are:
(1) Raw gravity and local pressure records sampled at 1 or 2 seconds, in addition to the same records decimated at 1‐minute samples (Level 1 products).
(2) Gravity and pressure data corrected for instrumental perturbations, ready for tidal analysis. This product is derived from the previous datasets, and is computed by one or several Analysis Centers (Level 2 products).
(3) Gravity residuals after particular geophysical corrections (including solid Earth tides, polar motion, tidal and non‐tidal loading effects). This product is also derived from the previous dataset and is computed by one or several Analysis Centers (Level 3 products)
