VORTEX2: Automated Surface Observing Systems (ASOS) 1-minute Data

Summary

This data set contains 1-minute resolution surface meteorological data from the Automated Surface Observing System (ASOS) stations located across the United States, including Guam. These data were retrieved from the National Climatic Data Center (NCDC) for the VORTEX2 2009 and 2010 field seasons (May 2009 through June 2009 and May 2010 through June 2010). Each of the two types of files, om1 and om2, consists of a compressed tar file containing one month of data, with individual files for each station in the United States. The data are in ASCII format.
