Abstract
Cloud water content and solid precipitation over the arctic cryosphere affects the radiation characteristic on the land surface. Ground-based quantitative observation of the solid precipitation over the arctic cryosphere has however a significant problem in terms of capture rate for solid precipitation. In addition, the visible and infrared remote sensing is not useful since the scattering property of sun shine can not be used and the ground surface temperature falls significantly over the arctic cryosphere. Development study of observation system for solid precipitation over the arctic cryosphere is therefore needed. In this study, the microwave satellite retrieval algorithm for the cloud water content and snow physical quantity over the arctic cryosphere was constructed. Estimated snow grain size, snow depth and cloud water content by using this algorithm was in comparatively good agreement with the in situ data in Yakutsk, Russia. This conclusion suggests that this algorithm is useful for the quantitative observation method for cloud water content and solid precipitation over the arctic cryosphere.
