Access NOx and NOy measurements on-line

Authors


Abstract

An archive of previously published, but not publicly archived, in situ measurements of NO1, NO2 and NOy (total reactive nitrogen) in the atmosphere is now accessible by anonymous ftp at the University of Michigan. Measurements from the nonurban surface, boundary layer, free troposphere and lower stratosphere, for all seasons over the past 10 years have been included in the archive. Any coincident measurements of other species or parameters, such as temperature or winds, have also been included. These data sets and the climatologies compiled from them will be used in conjunction with model results to assess our level of understanding of tropospheric photochemistry.
