Improved Cirrus Simulations in a General Circulation Model Using CARMA Sectional Microphysics
Contributor:Bardeen, C. G.; Gettelman, A.; Jensen, E.J.; Heymsfield, A.; Conley, A. J.; Delanoë, J.; Deng, Min; Toon, O. B.
We have developed a new cirrus model incorporating sectional ice microphysics from the Community Aerosol and Radiation Model for Atmospheres (CARMA) in the latest version of NCAR's Community Atmosphere Model (CAM5). ...
Relationships Between Ice Water Content and Volume Extinction Coefficient from in Situ Observations for Temperatures from 0° to -86°C : Implications for Spaceborne Iidar Retrievals
Contributor:Heymsfield, A.; Winker, D.; Avery, M.; Vaughan, M.; Diskin, G.; Deng, Min; Mitev, V.; Matthey, R.
An examination of 2 yr of Cloud-Aerosol Lidar Infrared Pathfinder Satellite Observations (CALIPSO) lidar observations and CloudSat cloud radar observations shows that ice clouds at temperatures below about -45°C frequently ...
Seasonal Variations of Antarctic Clouds Observed by CloudSat and CALIPSO Satellites
Contributor:Adhikari, L.; Wang, Z.; Deng, Min
The multiyear lidar and radar measurements obtained from the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) and CloudSat between June 2006 and May 2010 were used to investigate the seasonal and ...
Toward Understanding of Differences in Current Cloud Retrievals of ARM Ground-Based Measurements
Contributor:Zhao, C.; Xie, S.; Klein, S. A.; Protat, A.; Shupe, M. D.; McFarlane, S. A.; Comstock, J. M.; Delano, J.; Deng, Min; Dunn, M.; Hogan, R. J.; Huang, D.; Jensen, M. P.; Mace, G. G.; McCoy, R.; O'Connor, E. J.; Turner, D. D.; Wang, Z.
Accurate observations of cloud microphysical properties are needed for evaluating and improving the representation of cloud processes in climate models and better estimate of the Earth radiative budget. However, large ...
Evaluation of Several A-Train Ice Cloud Retrieval Products with in Situ Measurements Collected During the SPARTICUS Campaign
Contributor:Deng, Min; Mace, G. G.; Wang, Z.; Lawson, R. Paul
In this study several ice cloud retrieval products that utilize active and passive A-Train measurements are evaluated using in situ data collected during the Small Particles in Cirrus (SPARTICUS) field campaign. The retrieval ...
Observationally Based Evaluation of Cloud Ice Water in CMIP3 and CMIP5 GCMs and Contemporary Reanalyses using Contemporary Satellite Data, An
Contributor:Li, J.-L. F.; Waliser, D. E.; Chen, W.-T.; Guan, B.; Kubar, T.; Stephens, G.; Ma, H.-Y.; Deng, Min; Donner, L.; Seman, C.; Horowitz, L.
We perform an observationally based evaluation of the cloud ice water content (CIWC) and path (CIWP) of present-day GCMs, notably 20th century CMIP5 simulations, and compare these results to CMIP3 and two recent reanalyses. ...
Tropical Composition, Cloud and Climate Coupling Experiment Validation for Cirrus Cloud Profiling Retrieval Using Cloudsat Radar and CALIPSO LiDAR
Contributor:Deng, Min; Mace, G. G.; Wang, Z.; Okamoto, H.
A profiling retrieval algorithm for ice cloud properties, such as effective radius (re), ice water content (IWC), and an extinction coefficient, has been developed to use combined CloudSat radar reflectivity factor (Ze) ...
Single Aircraft Integration of Remote Sensing and In Situ Sampling for the Study of Cloud Microphysics and Dynamics
Contributor:Wang, Zhien; French, Jeffrey; Vali, Gabor; Wechsler, Perry; Haimov, Samuel; Rodi, Alfred; Deng, Min; Leon, Dave; Snider, Jeff; Peng, Liran; Pazmany, Andrew L.
Clouds are a critical component of the Earth's coupled water and energy cycles. Poor understanding of cloud–radiation–dynamics feedbacks results in large uncertainties in forecasting human-induced climate changes. Better ...
