Abstract
The AIRS infrared hyperspectral sensor on NASA AQUA platform will soon be operating for 10 years. The CrIS sensor on NPP/JPSS will extend the 1:30 polar orbit measurements of AIRS, which have been supplemented with the 9:30 orbit infrared hyperspectral measurements of IASI on EUMETSAT's METOP platform. These three instruments will together soon provide a time-series of the Earth's atmospheric and surface radiances that will span a long enough period to start to contribute to a climate data record. We will discuss the inherent accuracy and stability of these instruments, and especially strategies for combining these different instrument data records into a single coherent infrared radiances climate time series. In addition, we will present techniques for using the radiance time series record directly for climate change observations.
