Infrared Atmospheric Sounding Interferometer Level 1CEntry ID: gov.noaa.class.IASI_L1C
Abstract: ABSTRACT: The Infrared Atmospheric Sounding Interferometer is flown on METOP-A. The main goal is to provide atmospheric emission spectra to derive temperature and humidity profiles with high vertical resolution and accuracy. It is a Michelson interferometer with spectral coverage between 3.6 and 15.5 micrometers. At nadir, the instrument samples data at intervals of 25 km along and a cross track, each sample having a maximum diameter of about 12 km. The level 1C data is geo-located, calibrated and apodized.
CURRENTNESS REFERENCE: ground condition
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: For radiance and retrieval assimilations into numerical weather prediction models.

Quality LOGICAL CONSISTENCY REPORT: All the data are processed from level-0 to level-1C at EUMETSAT. Throughout this processing a number of quality checks are performed. For more information on this process please see the following document: Dossier definition des algorithmes, IA-DF-0000-2006 Ed: 4 Rev: 2 Date:01/10/2003 D. Blumstein
COMPLETENESS REPORT: Nominally, a granule is either 176 or ... 184 seconds long consisting of 22 or 23 scan lines of 8 seconds each. Each data record contains one scan line. Missing scan lines are the result of transmission errors from the satellite to the ground station.
