Met I 
3. Grassl 
Registration of meteorological data; 
measurements of the input and output 
mechanisms at the boundary layer of 
atmosphere and sea surface. 
Valuation of balance and transport/ 
deposition models. Quantitative determination 
of the input of aerial pollutants into 
the North Sea and the Baltic Sea. 
Installation of a measurement 
unit and implementation of 
investigations for the de 
termination of the pollutant 
deposition from the atmosphere 
into the North Sea and the 
Baltic Sea 
8.86 - 6.90 
1. BMU 
2. Uni Kiel, 
IfM 
3. Duinker 
Investigations on wet deposition (input). 
Components to be measured are diverse ions, 
heavy metals according to the PARCOM 
"grey list", and organic micro compounds. 
Study of an evaluation of the 
pollutant input via the atmosphere 
within the framework of PARCOM 
(North Sea) and HELCOM (Baltic Sea) 
3.87 - 2.90 
1. BMU 
2. GKSS 
3. Grassl 
Investigation about, and the testing of 
procedures, and the realization of studies 
on input via different pathways. 
Application, test, and improvement of model 
calculations; enquiry into input data to de 
termine regionally based fractions. 
Atmospheric deposition of 
trace elements into the 
North Sea 
until 1990 
2. GKSS 
3. Michaelis 
Calculation of backward trajectories; 
hindcasting of deposition measurements on 
Pellworm Island; estimate of atmospheric input 
into the North Sea; coastal meso-scale model. 
Deposition measurements on 
Pellworm Island 
starting 
in 1990 
2. GKSS 
The aim is to reveal trends by comparison 
with measurements carried out in 1984/85.
