摘要

The EarthCARE satellite mission objective is the observation of clouds and aerosols from low Earth orbit. The key spatial context providing instrument within the payload suite of 4 instruments is the Multi-Spectral Imager (MSI).The MSI will take data at 500m ground sample distance (GSD) over a swath width of 150 km via pushbroom imaging. One part of the MSI instrument will be a thermal IR optical unit (TIROU). We describe the design of the focal plane array for the TIROU, its time-delay and integration readout scheme and present results derived from its associated simulator.
