Paper Abstract
The application of infrared hyper-spectral sounder data to climate research requires the global analysis of multi-decadal
time series of various atmosphere, surface or cloud related parameters. The data used in this analysis has to meet
stringent global and scene independent absolute accuracy and stability requirements, it also has to be spatially and
radiometrically unbiased, manageable in size and self-contained. Self-contained means that the data set contains not
only a globally unbiased sample of the state of the Earth Climate system as seen in the infrared, it has to contain enough
data to contrast clear with average (cloudy) data and to allow an independent assessment of the radiometric and spectral
accuracy and stability of the data. We illustrate this with data from the Atmospheric Infrared Sounder (AIRS) and
Infrared Atmospheric Sounder Interferometer (IASI) data. AIRS and IASI were designed with fairly similar functional
requirements. AIRS was launched on the EOS Aqua spacecraft in May 2002 into a 705 km polar sun-synchronous orbit
with accurately maintained 1:30 PM ascending node. Essentially un-interrupted data are available since September
2002. Since October 2006 IASI is in a 9:30 AM polar orbit at 815 km altitude on the MetOp2 satellite, with data
available since May 2007.
