Calibrate AVHRR and TIMS Data
Use Calibrate AVHRR to calibrate AVHRR data from the NOAA-12 though -19 satellites. Bands 1 and 2 are calibrated to percent reflectance, and bands 3, 4, and 5 are calibrated to brightness temperature, in degrees Kelvin.
- From the Toolbox, select Radiometric Correction > Calibrate AVHRR.
- Select an input file and perform optional spatial and spectral subsetting, then click OK. The AVHRR Calibrate Parameters dialog appears.
- Select the satellite number from the Satellite drop-down button.
- Select output to File or Memory.
- Click OK.
Output bands 1 and 2 are in % reflectance, and output bands 3, 4, and 5 are in brightness temperature, in degrees Kelvin.
Use Calibrate TIMS to calibrate raw data from the NASA Thermal Infrared Multispectral Scanner (TIMS) to radiance in units of W/m2/μm/sr.
