Abstract

Field data collected during the GDF 93 project indicated that during polluted conditions (SO2(g) > 2 ppbv, NH3(g) > 0.5 ppbv), sulphate and ammonium concentrations in air increased through cloud chemistry by as much as 25%. Similarly, ammonia was seen to be consumed by cloud processing and decreased by up to 20%. In comparatively clean conditions (SO2(g) < 0.5 ppbv, NH3(g) < 0.5 ppbv), the sulphate loading of the aerosol was seen to remain constant, and ammonium was lost from the aerosol and outgassed as ammonia, increasing ambient ammonia concentrations by as much as 0.5 ppbv. An ideal cloud chemistry model predicted up to 20% more sulphate production than is implied by the bulk aerosol data set. A non-ideal cloud chemistry model was used to estimate the final ammonium loading of the aerosol, which is determined by the transformation from wet cloud droplet to dry aerosol particles below their deliquescence point. The non-ideal model showed that in three of the four cases ammonia outgassed from evaporating cloud droplets, consistent with field observations, but at variance with the ideal chemistry model. The results indicate that in low pollution conditions clouds act to re-equilibrate reduced nitrogen in the aerosol phase with gaseous ammonia. The outgassed ammonia will then be rapidly deposited to semi-natural ecosystems downwind of such clouds.

Abstract

The 1993 Ground-based Cloud Experiment on Great Dun Fell used a wide range of measurements of trace gases, aerosol particles and cloud droplets at five sites to study their sources and sinks especially those in cloud. These measurements have been interpreted using a variety of models. The conclusions add to our knowledge of air pollution, acidification of the atmosphere and the ground, eutrophication and climate change. The experiment is designed to use the hill cap cloud as a flow-through reactor, and was conducted in varying levels of pollution typical of much of the rural temperate continental northern hemisphere in spring-time.

84. Differential cross section and analyzing power for elastic scattering of protons on 6Li below 2.2 MeV

Author

Skill, M., Baumann, R., Keil, G., Kniest, N., Pfaff, E., Preiss, M., Reiter, G., Clausnitzer, G., Haller, M., and Kretschmer, W.

Abstract

Differential cross section dσdΩand analyzing power Ayof elastic 6Li(p,p)6Li scattering have been measured in the energy range 0.4 MeV ⩽ Ep⩽ 2.2 MeV. The angular distributions were obtained at thirteen different angles between θlab= 40° and 160° with statistical uncertainties of less than 2 × 10−3. The data show a resonance-like behaviour in the excitation functions for dσdΩand Aynear Ep= 1.8 MeV (i.e. Ec.m.= 1.56 MeV). An energy-dependent phase-shift analysis has been performed from which resonance parameters have been deduced. The analysed data are well described in the whole energy range and support the predictions of recent refined resonating-group calculations.
