THE OPERATIONAL IASI LEVEL 2 PROCESSOR

The operational IASI level 2 processor will be part of the EPS Core Ground Segment. Starting with level 1c data the IASI level 2 processor generates vertical profiles of temperature and humidity, ozone columns of deep layers, and columnar amounts of carbon monoxide, methane, nitrous oxide, and carbon dioxide, along with surface temperature, surface emissivity, cloud amount, cloud-top height, and cloud phase. The processor not only makes use of IASI data but also utilises information from the companion instruments AVHRR, AMSU-A, MHS, as well as level 2 products from the ATOVS instrument suite.
