<title>Spectroscopic measurements of spatiotemporal variability of water vapor, methane, and carbon oxide contents in the atmosphere</title>

Abstract

The results are given of the parallel measurements of water vapor, methane and carbon oxide in the atmosphere of St.Petersburg (Petrodvorets), Zvenigorod and Obninsk in July-August 1999. The measurement data obtained at the three sites made it possible to represent the spatiotemporal variability of the contents of each of the atmospheric gases studied for the European territory of Russia (ETR) in the form of the chart "latitude-day-content" with the use of the splines of mean daily contents. The dependence of the gases variability on synoptic conditions over the ETR was determined.
