Acidification problems in developing countries are expected to become more prevalent in the coming decades. Assessments of means of abatement strategies are likely to become of vital interest. This paper presents some preliminary results of modelling of acidic deposition due to anthropogenic …

Measurements of solar UV-racliation in a small Sweclish network are presented for 1996. this report can be regarded as a supplement to a previous report, Josefsson (l996) where the results of the previous five years were reported, and where details not presented in this small repor! can be found. …

The project was initiated by the Swedish Environmental Protection Agency in order to improve the basis for making standards for PM-10 concentrations in urban air. Model development has been made for Norrköping and Gothenburg. Modelling has been necessary of both long-range and local contributions.

We have been doing precipitation experiments with a numerical weather prediction model. The model has been run with three different horizontal resolutions, 22, 11 and 5 km respectively. The results show that the model is able to forecast reasonable precipitation amounts in a broad sence, but it has …

This report summarises the quality control, quality assurance and measurements of total ozone at Norrköping and Vindeln during the period 1994-1996. To ensure the quality and link the observations closely to the other ozone data participation in intercomparisons and intemational campaigns are …

General Circulation Models (GCMs) are used to study the change of climate due to increases in greenhouse gases in the atmosphere. As GCMs operate on !arge spatial scales, and, furthermore, as the GCM-simulated temporal resolution corresponds to monthly averages at best, the usefulness of GCM data …

Accurate measurements of incoming solar radiation at the Earth' s surface are made by present ground based networks. The data are of high quality and high  sampling frequency but there is a lack of spatial coverage. Areas of great interest may not have any observations at all. Since clouds are …

The first version of the Rossby Centre regional climate model (RCA) has now been developed. The RCA model is based on a parallel coding of the operational weather forecast model HIRLAM. Some modifications have been done on the model formulation, especially in its surface/snow/soil scheme, in an …

The performance of a global coupled atmosphere-ocean general circulation model, HadCM2, in simulating present-day climate in Sweden and Northern Europe is studied. The study is motivated by the use of HadCM2 within the SWEdish regional CLimate Modelling programme SWECLIM. In particular, HadCM2 …
