Saral validation report, cycle 156
Cycle date | 2021-11-15 - 2021-12-20 |
---|---|
Cycle quality | During this cycle, mispointing levels are similar to that of the previous cycle. These levels of mispointing are due to attitude deviation, and explains the higher percentage of rejected data during the validation process. Data quality is still slightly impacted by these events, so that around 5.06 % of the data is rejected during the validation process mainly due to mispointing. 84% of pass 134 is rejected by threshold on multiple criteria (orbit-range, sla, range_number, range_rms, off_nadir_angle, wet_tropo, swh, ssb, sig0, sig0_number, sig0_rms, wind_speed) due to the station keeping maneuver. (see section ). |
Missing data | Cycle 156 has no missing pass but, but track 134 is partially missing due to the station keeping maneuver that occurred on 20/11/2021 between 12:18:14 and 12:18:17 (18.13% of missing data on this track but only 9.13% are over ocean). |
