The IASI products are now being produced as part of the NESDIS Common Cloud Format (NCCF) Hyper-Spectral Enterprise
Alogrithm Package (HEAP). The link to these products is NCCF IASI Soundings Products
All the trace gases products derived from the Infrared Atmospheric Sounding Interferometer (IASI) and the NOAA Unique
Combined Atmospheric Processing System (NUCAPS) are not validated yet by the science community and users should use them
with precaution and at their own risks. These products will be updated soon after a through science validation.
Infrared Atmospheric Sounding Interferometer (IASI), is a hyperspectral infrared sounder residing on the European Space Agency's (ESA) MetOp series of polar orbiting satellites. These data are made available to NOAA through the International Joint Polar-Orbiting Operational Satellite System (IJPS) agreement. The first priority of the IASI Product Processing System (PPS) is to generate radiance products that are produced using Level 1C data, which are ingested in a pipeline mode from the European Organization for the Exploitation Meteorological Satellites (EUMETSAT), applied to spectral and spatial sub-setting. The system generates Level 1C Thinned (L1CT) radiance and Level 2 profile products. Currently the IASI level 2 products from MetOp-2 satellite include temperature and humidity profiles with a vertical accuracies of 1 degree Kelvin and 10% per 1-km layer respectively, trace gases, and the cloud cleared radiances (CCR) on a global scale and these products are available to the operational user community.
