Global satellite gravity data products for prompt detection of short-term Mass Change (MC)

-Variable 1: observation time, expressed as GPS time in continuous seconds since 01-Jan-2000 11:59:47 UTC -Variables 2–4: longitude, latitude, and altitude of the twin satellites’ midpoint at that epoch -Variable 5: LGD_full, representing the unfiltered, full-spectrum LGD value -Variable 6: LGD_band, containing LGD signals retained after bandpass filtering -Variable 7: LGD_low, representing LGD signals below 1 mHz, which is extracted from L2-synthesized LGD -Variable 8: LGD_L2, the synthetic LGD from L2 SH coefficients up to 60, limited to the frequency band below 10 mHz -Variable 9: LGD_clm, LGD climatology, which is the synthetic LGD from the climatological estimates of the SH coefficients
