The Infrared Atmospheric Sounding Interferometer (IASI) onboard the European MetOp satellite, was launched in October 2006. IASI produces temperature and humidity profiles with vertical accuracies of 1 degree Kelvin and 10 % per 1-km layer respectively. The first priority of the IASI processing system is to generate radiance products from data ingested in a pipeline mode from EUMETSAT. These radiances undergo sub-setting, Principal Component Analysis (PCA) reconstruction, and global gridding. Subsequently these radiance products are distributed to users as BUFR, NetCDF and BINARY files. All levels of data products are made available at the user specified locations, as subset files, and as gridded subsets.
The NOAA Unique Combined Atmospheric Processing System (NUCAPS) was developed to generate (1) spectrally
and spatially thinned radiances, (2) retrieved products such as profiles of temperature, moisture, trace
gases and cloud-cleared radiances, and (3) global validation products such as radiosonde matchups and
gridded radiances and profiles. The thinned radiance products are produced in BUFR format using the
NetCDF4 Reformatting Toolkit (N4RT) and are tailored to specifically Numerical Weather Prediction (NWP)
centers. The NUCAPS Environmental Data Records (EDR) products are archived in Comprehensive Large
Array-Data Stewardship System (CLASS) for non-real time users.
These products are derived from the Cross-track Infrared Sounder (CrIS) and Advanced Technology
Microwave Sounder (ATMS) currently onboard the Suomi National Polar-orbiting Partnership (SNPP)
satellite and later will be available from the Joint Polar Satellite System (JPSS-1 and JPSS-2).
The GOES Satellite Cloud Product (SCP) is a text product that compliments the National Weather Services (NWS) Automated Surface Observation System (ASOS). These text products, sometimes referred to as ASOS SCP, detect the cloud cover conditions over the ASOS stations, and list them by state.
