Figure 6.3 Validation of dust image with OMI UVAI on October 23, 2007 at UTC time 04:55. (a) RGB image; (b)Dust image; (c) OMI UVAI image; (d) The difference between UVAI and dust image. Table 6.2 The error analysis in the comparisons between MODIS smoke image and OMI UVAI images with different UVAI values.
