  3. Table of J31/satellite coincidences during ITCT 2004

  4. ICARTT 2004 AATS-14/MODIS Coincidences • Eight cases w/MODIS data • July 12, 16, 17, 21,22,23; August 2, 8 ICARTT 2004 AATS-14/MISR Coincidences • Four events • July 20,22, 29; August 7

  5. MISR 20 July • Moderate AODs • Limited MISR data

  6. J31 descent J31 ascent

  7. Terra overpass: 1543 UT

  8. MISR V16 Note: V16 MISR AODs > 0 are available only within blue box shown in earlier slide. These AATS-14 data are means for all AATS data points shown in previous slide.

  9. MISR V16 Note: These AATS-14 means only include those data points within the MISR blue box, as shown in earlier slide.
