From Oct. 25-28, 2010, scientists from around the world gathered in New Orleans for the second-ever symposium on science born of NASA's "A-Train."

The Afternoon Train, or "A-Train," for short, is a constellation of satellites that travel along the same track as they orbit Earth. Four satellites currently fly in the A-Train - Aqua, CloudSat, CALIPSO, and Aura. Three more satellites -- Glory, GCOM-W1, and OCO-2 -- are scheduled to join the configuration in 2011, 2012, and 2013, respectively.

This page features a selection of some of the A-Train's "greatest hits" gathered into two sections. The first contains overview materials giving a big-picture look of the A-Train and NASA satellites. The second section contains mostly visualizations featuring a single instrument or instruments on A-Train satellites. (For the purposes of this page, each visual has been labeled with the A-Train data set it was produced from, but keep in mind, visuals are often the product of many data sets from many different satellites.)
