A basic concept for a cross calibration between EOS-AM1/ASTER and MODIS is proposed together with the method for assessment of cross calibration accuracy. The results from preliminary assessment on atmospheric transparency differences between two wavelength regions of ASTER/TIR and MODIS by using LOWTRAN-7 show a possibility of the proposed cross calibration. The differences between atmospheric transparency for ASTER/TIR band 11 and MODIS band 29 and ASTER/TIR band 14 and MODIS band 31, respectively were assessed with LOWTRAN-7 under the assumption of 1976 US standard and subarctic winter atmosphere and the ground cover of 0% albedo. The transparency of the atmosphere in these wavelength regions are not so different that it is possible to calibrate each other if a homogeneous target is used and the pixels of both sensor are collocated. In addition, the database which is required for cross calibration is also discussed in this paper.
