Bryant Figure 2: Maps of contoured AI values for Etosha Pan region

The first map, to the right, shows absorbing aerosol index (AI) values from N7-TOMS data (that is, data collected by the Total ozone mapping spectrometer aboard the Nimbus-7 satellite). these values are comparable to AI index values for other major southern Hemisphere dust sources.

This second map shows AI values derived from EP-TOMS data (that is, data collected by the Total ozone mapping spectrometer aboard the Earth Probe satellite. These values are lower than those derived from the N7-TOMS data but are still consistent with indications of a major regional dust source.
