== MetOp-A IASI data problem 21 Aug - 23 Sep 2019 == | |||
* Per EUMETSAT Service Alert 5119: "Since 21 August 2019 a problem with the geolocation software has resulted in missing data in part of the IASI products from Metop-A. The problem causes missing geolocation and cloud information in the IASI L1 products, and empty contents in the IASI L2 products. This is affecting the global products. Impact on the regional EARS-IASI products is still being investigated. EUMETSAT is looking into the problem and hopes to provide a fix soon." | |||
* Initial impact was on 21 August; beginning about 29 Aug there was a slow decline in the number of obs at 00 and 12 UTC, and a much larger decrease at 06 and 18 UTC. After 13 Sep data counts were very low or zero at 06 and 18UTC and by 18 Sep 00UTC the data was completely missing. | |||
* Emails from Stephanie Guedj at EUMETSAT forwarded to the ITWG list indicated that the anomaly is related to the drift/inclination of the Metop-A spacecraft, and that a fix was being worked on. | |||
* The data counts began to recover on 23 September, reaching normal levels on 24 September. | |||
