Saral validation report, cycle 135

Cycle date2019-11-11 - 2019-12-16
Cycle qualityMispointing levels during this cycle are higher than during the previous cycles. These levels of mispointing are due to attitude deviation, and explains the higher percentage of rejected data during the validation process. Data quality is severly impacted by these events, so that around 26,08 % of the data is rejected during the validation process mainly due to mispointing (see section ).
Missing dataCycle 135 has no missing pass but some passes have a large number of missing measurements due to attitude deviation.
Crossover standard deviation(*)5.02 cm
SLA standard deviation(*)(**)9.47 cm

(*)When using a selection to remove shallow waters (1000 m), areas of high ocean variability and high latitudes (> |50| deg)
(**) relative to a 7-year mean (cycles <= 33) or 20-year mean (cycles >=34)
