Abstract
This letter reports a statistical method to estimate
detector-dependent systematic error in Moderate Resolution
Imaging Spectroradiometer (MODIS) thermal infrared (TIR)
Bands 20–25 and 27–36. There exist scan-to-scan overlapped
pixels in MODIS data. By analyzing a sufficiently large amount of
those most overlapped pixels, the systematic error of each detector
in the TIR bands can be estimated. The results show that the Aqua
MODIS data are generally better than the Terra MODIS data
in 160 MODIS TIR detectors. There are no detector-dependent
systematic errors in Bands 31 and 32 for both Terra and Aqua
MODIS data. The maximum detector errors are 3.00 K in Band 21
of Terra and −8.15 K in that of Aqua for brightness temperatures
of more than 250 K.
