The data are geographic and atmospheric measures on a very coarse 24 by 24 grid covering Central America. This data was provided by the NASA Langley Research Center Atmospheric Sciences Data Center as part of the ASA Data Expo in 2006. Monthly averages of a set of atmospheric measurements are provided for Jan 1995 to Dec 2000. A subset of this data is available from the GGally package.
