High-Resolution Infrared Radiation Sounder (HIRS) Brightness Temperature, Version 2.6

The data are converted into a NOAA HIRS Clear-Sky Channel 12 TB CDR at NCDC. The intermediate products include HIRS all-sky (binary), HIRS clear-sky (binary), and HIRS Limb-corrected clear-sky (ascii) data.

The HIRS all-sky data are brightness temperatures for channels 1-19 processed from HIRS level 1b records. Cloud-removal procedures are performed to the all-sky data to generate clear-sky datasets. Limb-correction is then applied to clear-sky observations to obtain limb-corrected brightness temperatures.
