Abstract: ABSTRACT: The level 1C IASI data are collocated to points on a 3x3 degree global grid. This product is generated daily and consists of two files, one for ascending orbits and the other for descending orbits.


Direct Spatial Reference: Point
SDTS Point and Vector Object Type: Point
Point and Vector Object Count: 7320

Electronic download (FTP) of the data is free. There is a fee for copies of data on physical media. Optical disks are $25.00 per unit and magnetic tape is $100 per unit. Price does not include additional service and handling costs.

Purpose: PURPOSE: The main goal of the IASI is to provide atmospheric emission spectra to derive temperature and humidity profiles with high vertical resolution and accuracy. Additionally it is used for the determination of trace gases such as ozone, nitrous oxide, carbon dioxide and methane, as well as land- and sea surface temperature and emissivity and cloud properties.
