Comparisons of Cloud Heights Derived from Satellite and Atmospheric Radiation Measurement Surface Lidar Data
Cloud heights derived from single-channel, satellite infrared data can be relatively uncertain under certain conditions such as overlapped or optically thin clouds. During the daytime, optical depths derived from 0.63 μm visible (VIS) reflectances are used to adjust the altitude of optically thin clouds. Without the adjustment, the cloud heights are significantly underestimated diminishing the ...
متن کاملGeometric Cloud Heights from Meteosat and Avhrr
Geometric cloud height estimation provides an alternative to cloud top temperature methods if two satellites view the same cloud. First we demonstrate the stereo cloud height derivation with a combination of Meteosat 7 and Meteosat 5 5 km resolution Infrared data. Comparison with the temperature technique shows consistency in the majority of the clouds, but some differences. This demonstrates t...
متن کاملAssigning Heights to Cloud Motion Vectors
Satellite derived cloud motion vector (CMV) production has been troubled by inaccurate height assignment of cloud tracers, especially in thin semi-transparent clouds. This paper presents the results of an intercomparison of operational height assignment techniques. Heights are assigned by one of three techniques when the appropriate spectral radiance measurements are available: the infrared win...
متن کاملDirect measurement of barrier heights in protein folding.
A serious limitation in the study of protein folding reactions resides in the lack of experimental methods to measure the absolute height of the free energy barrier. This is particularly unfortunate given that if folding barriers are small, as theory predicts, it might be possible to resolve folding mechanisms directly. Here we explore the performance of a recently developed method to extract f...
متن کاملRelationship between Topography and Daytime Cloud Activity around Tibetan Plateau
The relationship between topography and daytime cloud activity over the Tibetan Plateau and surrounding areas was examined by using Geostationary Meteorological Satellite (GMS) Visible (VIS) and Infrared (IR) images during the premonsoon, and monsoon periods in 1998. Previous studies using IR images have already confirmed the strong diurnal variation of convective activity over the Tibetan Plat...
