Abstract :
Several channels in the near-IR spectral region were implemented on the Moderate Resolution Imaging Spectroradiometer (MODIS) for remote sensing of water vapor and cirrus clouds from the Terra spacecraft platform. Daily and seasonal variations of column atmospheric water vapor amounts have been observed reliably from MODIS channels located within and around the 0.94-micron water vapor band. Daily and seasonal variations of high clouds have also been observed from the 1.375-micron cirrus-detecting channel. This channel has an additional advantage-it allows significant improvement in detecting polar clouds during the daytime in comparison with channels on traditional meteorological satellites
