[Jason-1 & 2] Delivery delay on IGDR products due to Met anomaly

Category: Operational news

Due to an anomaly in meteorological fields, the JAson-1 and Jason-2 IGDR have some delays.

Due to an anomaly during the implementation of the ECMWF model update this week, the forecast and analysis surface pressure grids, which are used to calculate atmospheric range corrections, were degraded from June 22 to June 23. The problem has been corrected and the Met files data have returned to their nominal quality. The corrupted analyzed Met files have been reprocessed and redelivered. As a consequence, the impacts on offline altimetric products are listed below:
- for Jason-2: since we stopped the IGDR production as soon as the problem on Met data occurred, no corrupted IGDR products have been processed.
We only have a delivery delay:
     .  the IGDR for day June 22 has been produced on June 25 (delay=2 days).
     .  the IGDR for day June 23 has been produced on June 25 (delay=1 day).
     .  the IGDR for day June 24 has been produced on June 25 (no delay). - for Jason-1: since we stopped the IGDR production as soon as the problem on Met data occurred, no corrupted IGDR products have been processed.
We only have a delivery delay: 
     .  the IGDR for day June 22 has been produced on June 25 (delay=1 days).
     .  the IGDR for day June 23 has been produced on June 25 (no delay). No impacts are foressen on GDR products. We apologize for the inconvenience.
