Macrophysical properties of specific cloud types from radiosonde and surface active remote sensing measurements over the ARM Southern Great Plains site

Atmospheric and Oceanic Science Letters 2017年第1期10卷 29-35页

作者： ZHANG Jin-Qiang CHEN Hong-Bin Key Laboratory of Middle Atmosphere and Global Environment Observation Center of Technical Support and Service IAPCA

Accurate observation of clouds is challenging because of the high variability and complexity of cloud types and *** using the long-term cloud data collected during the ARM program at the Southern Great Plains central facility during 2001-2010,the consistencies and differences in the macrophysical properties of clouds between radiosonde and ground-based active remote sensing are quantitatively evaluated according to six cloud types：low;mid-low（ML）;high-midlow;mid;high-mid（HM）;and high.A similar variability trend is exhibited by the radiosonde and surface observations for the cloud fractions of the six cloud ***,the magnitudes of the differences between the two methods are different among the six cloud types,with the largest difference seen in the high *** distribution of the cloud-base height of the ML,mid,and HM clouds agrees in both methods,whereas large differences are seen in the cloud-top height for the ML and high *** cloud thickness variations generally agree between the two datasets for the six cloud types.
