It is well known that the varying geometrical relationships between the Sun and the Earth throughout the year can affect to some degree the performance of the instruments on-board Earth orbiting satellites. Following the commissioning of MetOp-A, EUMETSAT and NOAA have continued monitoring the long term trends in in-orbit performance of AVHRR, HIRS and AMSU-A. The data acquired since the launch of the satellite has allowed studying how the yearly seasonal variations, as well as aging, have affected the instrument performance. This paper presents the evolution of the performance of the AVHRR, HIRS and AMSU-A for more than six years since the launch of the MetOp-A satellite, as well as the early performance results for MetOp-B.
