| Title: | Surface radiation, cloud forcing and greenhouse effect in the Alps / Christoph Marty. |

| Abstract: | Studies surface radiation fluxes, cloud forcing and greenhouse effect in Swiss Alps, concentrating on measurement method and analysis of longwave radiation. Alpine Surface Radiation Budget (ASRB) network began in 1994 and 11 stations at different heights measure short- and longwave downward radiation, air temperature and humidity, with reflected shortwave and emitted longwave radiation measured at four larger stations, and then used to estimate upward fluxes at other stations. Develops new correction method permitting accurate measurements of short- and longwave radiation fluxes in alpine conditions. Use of ASRB network gave regional differences and altitude gradients of surface fluxes and quantified surface fluxes. Algorithm developed allowed investigation and determination of cloud forcing in alpine region, positive above 2000 m a.s.l. Employing radiative transfer model Modtran allowed determination of yearly and seasonal means of greenhouse flux at all ASRB stations. Lower greenhouse fluxes were found at higher stations. Demonstrates that decrease of longwave downward radiation and greenhouse effect with altitude is driven by decreasing water vapour content. Greenhouse effect amplifies longwave downward radiation by factor of 2.5. |
