Radiation and turbulence parameterizations at Ny-Alesund, Svalbard Islands (scientific note)

概要

論文の詳細を見る
Two experimental campaigns were carried out at Ny-Ålesund during the spring of 1998 and the spring-summer of 1999 with the aim to study the daily evolution of surface turbulence and the influence of clouds on the surface radiation balance. Parameterizations of the surface roughness were derived from turbulence measurements performed with a sonic anemometer. The value of the roughness length was calculated. It was highly variable because of snow drift and changing surface conditions. The applicability of two long-wave incoming radiation parameterizations reported in literature was tested with data collected during the experiments.
