10. Activity as a Regional Center

11. Activity as a Regional Center
1984 – Pyranometer comparison
Purpose: possible and expectable devations between the pyranometers operating in different countries
Norway, UK, Switzerland, Poland, Hungary, GDR, FRG, Turkey, Austria
Results published by the WMO (Instruments and observing methods report No 16)

12. Activity as a Regional Center
1997 – pyrheliometer comparison
participating countries:
Austria, Czech Republic, Slovakia, Poland, Hungary
Decreased interest for regional pyrheliometer comparison (it is solved in Davos)
New idea is welcome for extensing the activity as an RC

13. A possibility Comparison of pyranometers?
Field intercomparison was recently organised by Croatia for our region
Comparison of calibration methods?
A possible reality: comparison of pyrgeometers

14. Our standard pyrgeometers
EPPLEY PIR radiometer
Calibrated and modifyed in Davos
CGR 4 pyrgeometer
secondary standard
LW network – project-oriantated
