Presentation Transcript

  1. Continuous 222Radon measurements within the CE-Atmosphere network M. Schmidt, I. Levin, H. Sartorius, R. Neubert, J. Hatakka L.Tositti, M. Zimnoch, V. Kazan,

  2. Radon measurementsUHEI-IUP ( ) / LSCE ( ) / BfS ( )/ FMI ( ) UoB ( ) / ANSTO ( )

  3. CARBOEUROPE-IP WP 2.1222Rn Intercomparison • 222Rn ICP between UHEI and LSCE was performed 3 times (Mace Head, Gif-sur-Yvette, PUY) • 222Rn ICP between UHEI and BfS at Schauinsland several times. • 222Rn ICP between UHEI and FMI • 222Rn ICP between UHEI and ANSTO at Lutjewad within the next weeks.

  4. 222Rn Intercomparison at PUYUHEI/LSCE

  5. 222Rn Intercomparison at PUYUHEI/LSCE

  6. 222Rn Intercomparison at SCHUHEI/BfS

  7. 222Rn Intercomparaison at PallasUHEI/FMI

  8. 222Rn measurements at Mt Cimone(Bq/m3)

  9. Schauinsland - Mt Cimone

  10. We should include all labs and put together all results. • How to correct for disequilibrium between Radon and Radon daughters ? • We should have a short Radon workshop to discuss measurement / calculation /disequilibrium issue ?

  11. terrestrial -dose rate is as proxy for 222Rn flux Szegvary, Thomas

  12. Seasonal variation of estimated average 222Rn flux values for (a) 5° latitudinal bands and (b) 5° longitudinal bands

  13. Observed and simulated 222Rn concentrations (with TM5 atmospheric transport model) for the same period based on a standard 222Rn source term (STD) and the source term presented in this study (EU).
