Calibrates POES (TIROS) areas.
TIRCAL area [keyword]
The FULL option calibrates each group of five image lines throughout the entire area. The QUICK calibration uses the average calibration for the first five good lines and applies that calibration to the entire area; thus, it runs more quickly.
The quick calibrated data shows only slight differences visually. Do not rely on the quick calibration for scientific purposes. Temperature differences of 2° to 3° Kelvin with radiance differences have been observed at the end of GAC areas.
This entry applies a complete calibration to area 4200.
