* (User Notification Service message 3034) IASI TOP upload (on-board processing update). This update will improve the non-linearity correction for Metop-B IASI. An improvement of product quality will be seen in band 1 and can reach 0.2K, depending on scene temperature, pixel number and wavelength. | * (User Notification Service message 3034) IASI TOP upload (on-board processing update).

* The GEOS-5 FP system responded immediately to the change by adjusting the mean term in the radiance bias corrections so there was no lasting effect in the observation statistics for the affected channels. There was also a small adjustment in some MetOp-A IASI channels at the time of the change which quickly diminished. | * The GEOS-5 FP system responded immediately to the change in the 18z analysis by adjusting the mean term in the radiance bias corrections so there was no lasting effect in the observation statistics for the affected channels.
