Atmospheric  inputs  into  the
North  Sea  and  the  Baltic  Sea

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  determination ­
  of  the  pollutant
deposition  from  the  atmosphere
into  the  North  Sea  and  the
Baltic  Sea

8.86  -  6.90

1.  BMU

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  determine ­
  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.
