Geophysical Corrections Monitoring

Source: L2 GDR-A (all acquisition modes) · Variables: mod_dry_tropo_cor_01, mod_wet_tropo_cor_01, inv_bar_cor_01, hf_fluct_total_cor_01, iono_cor_01, iono_cor_gim_01, sea_state_bias_01_ku, ocean_tide_01, ocean_tide_eq_01, load_tide_01, solid_earth_tide_01, pole_tide_01

The atmospheric and geophysical range corrections at 1 Hz. These are 1-way corrections that are added to the range (or subtracted from the height); flag_cor_applied_20_ku shows which were applied to each measurement's height (ie the tide, inverse barometer and dynamic atmosphere corrections over ocean only). The sea state bias is not provided in Baseline-F.

Statistics use every 1 Hz measurement of the cycle within each area. Std Dev is the population standard deviation, RMS the root mean square.
