NOAA Climate Data Record (CDR) of Intersatellite Calibrated Clear-Sky High Resolution Infrared Radiation Sounder (HIRS) Channel 12 Brightness Temperature Version 3

HIRS Ch12 Brightness Temperature

browse graphicNOAA CDR HIRS Ch12 Brightness temperature
The High-Resolution Infrared Radiation Sounder (HIRS) of intersatellite calibrated channel 12 brightness temperature (TB) product is a gridded global monthly time series product spanning from 1979 to the most current full year, updated monthly. Among the twenty channels in the HIRS instrument, channel 12 measures upper tropospheric water vapor (UTWV). Multiple polar orbiting satellites in the NOAA Polar-orbiting Operational Environmental Satellite (POES) series and MetOp-A have carried HIRS instruments. Due to the independence in calibration of the individual HIRS instruments, biases exist between satellites. Examination of the intersatellite biases shows that the biases are scene brightness temperature dependent. These HIRS channel 12 measurements from the NOAA POES and MetOp-A are calibrated to a baseline satellite based on intersatellite bias correction data. The differences from the last version include that the dataset is now provided as monthly mean 2.5x2.5 degree latitude/longitude in netcdf format. This CDR is key to understanding water vapor feedback climatology and has been used to study long-term water vapor variability, to evaluate climate models, and to study large-scale atmospheric circulations.

Purpose This dataset provides advanced scientific researchers a high quality Climate Data Record (CDR) of upper tropospheric water vapor along with HIRS brightness temperatures that are suitable for long-term global studies and climate monitoring of upper tropospheric water vapor. These global observations play an important role in better modeling and understanding of tropical convection and its role in weather-climate connections from intraseasonal to interannual time scales.
Use Limitations
  • The data are limited to clear-sky observations.
