== IASI MetOp-A calibration change 30 Sep 2019 09:00UTC == | |||
* EUMETSAT announcement 5056 - The non-linearity correction tables for Metop-A IASI are planned to be updated. The impact on the Metop-A IASI level 1c radiances will be around 0.1-0.2K depending on scene temperature. | |||
* RadMon plots show some impact of the calibration change. The bias correction adjusted for the change. | |||
