Cirrus Microphysical Properties and Air Motion Statistics Using Cloud Radar Doppler Moments. Part I: Algorithm Description
The first three moments of the millimeter-wavelength radar Doppler spectrum provide valuable information regarding both cloud properties and air motion. An algorithm using these Doppler radar moments is developed to retrieve cirrus microphysical properties and the mean air vertical motion and their errors. The observed Doppler spectrum results from the convolution of a quiet-air radar reflectiv...
متن کاملImpact of Cloud Model Microphysics on Passive Microwave Retrievals of Cloud Properties. Part I: Model Comparison Using EOF Analyses
The impact of model microphysics on the relationships among hydrometeor profiles, latent heating, and derived satellite microwave brightness temperatures TB have been examined using a nonhydrostatic, adaptive-grid cloud model to simulate a mesoscale convective system over water. Two microphysical schemes (each employing three-ice bulk parameterizations) were tested for two different assumptions...
متن کاملCirrus Cloud Microphysical Property Retrieval Using Lidar and Radar Measurements. Part I: Algorithm Description and Comparison with In Situ Data
A retrieval algorithm is described to estimate vertical profiles of cirrus-cloud ice water content (IWC) and general effective size Dge from combined lidar and radar measurements. In the algorithm, the lidar extinction coefficient s is parameterized as s 5 IWC[a0 1 (a1/Dge)] and water equivalent radar reflectivity factor Ze is parameterized as Ze 5 C9(IWC/ri) , where a0, a1, C9, and b are const...
متن کاملGround-Based Cirrus Observation in the Japanese Cloud and Climate Study: A Sonde System for Radiation and Cloud Microphysics Measurement
Clouds play a crucial role in radiative energy budget and water cycle in the earth-atmosphere system. In order to understand processes such as global warming and to improve assessment of climate change, it is necessary to develop climate models which properly take into account radiation and cloud processes. In addition, it is also important to improve satellite monitoring systems for measuring ...
متن کاملSimulating aerosol microphysics with the ECHAM/MADE GCM – Part I: Model description and comparison with observations
The aerosol dynamics module MADE has been coupled to the general circulation model ECHAM4 to simulate the chemical composition, number concentration, and size distribution of the global submicrometer aerosol. The present publication describes the new model system ECHAM4/MADE and presents model results in comparison with observations. The new model is able to simulate the full life cycle of part...
