We derive an analytical expression for the deposition velocity of H2 on soil, vd, which explicitly describes the dependence of vd on the average soil moisture, and temperature, T. It is based on the solution of the equation for vertical diffusion in

This paper presents an overview of the global large-scale aspects of tropospheric ozone. It describes and quantifies the major sources of tropospheric ozone, namely stratospheric influx and tropospheric photochemistry, which today contribute on the o

OH and the major parameters determining its concentration were measured during a field campaign in August 1994 at Mankmoos, a rural, relatively unpolluted site in northeastern Germany. The measured OH concentrations were previously shown to depend ma

The Southern Hemisphere commands an increasing interest among atmospheric chemists. It has smaller and less industrialized continents than the Northern Hemisphere and thus enjoys lower emissions of anthropogenic and biogenic pollu tants. As a conse

This paper explores a new approach to estimating atmospheric hydroxyl radical concentrations from regional measurements of a suite of hydrocarbons. The approach is guided by the study of a suite of synthetic tracers, i, with uniform continental sourc

Absolutely calibrated in-situ measurements of tropospheric hydroxyl radicals, formaldehyde, sulfur dioxide, and naphthalene (C10H8) were performed by long-path laser absorption spectroscopy during the field campaign POPCORN. The absorption light path

Ambient mixing ratios of NO, NO2, and O3 were determined together with the photolysis frequency of NO2, \({J_{N{O_2}}}\), at a rural, agricultural site in Germany. The data were collected during the POPCORN-campaign from August 1 to August 24, 1994,
