AVHRR Deep Blue papers published and featured in EOS

True-color and AOD maps for an example scene covering South America

Figure shows (a) MODIS Aqua true-color image, (b) MODIS AOD at 550 nm from Collection 6, and (c) the new AVHRR AOD at the same wavelength from NOAA18, for a smoke event over South America on 7 September 2006. This shows an example of the comparability of the two products.

We are pleased to report that papers describing our AVHRR Deep Blue data set (version 1) have been published in the Journal of Geophysical Research - Atmospheres. These two papers describe the algorithms used to create the data sets, and provide an evaluation of them through comparisons to ground-truth data and other satellite products. The references for these papers are as follows:

The importance of this work and the new data set's potential for long-term analysis of aerosol loading were recognized by AGU journal articles, and the papers were the subject of a joint Research Spotlight in EOS magazine. The highlight can be read here.
