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 ...
On the Role of Sloping Terrain in the Forcing of the Great Plains Low-Level Jet
Contributor:Parish, Thomas R.; Oolman, Larry D.
The summertime Great Plains low-level jet (LLJ) has been the subject of numerous investigations during the past several decades. Characteristics of the LLJ include nighttime development of a pronounced wind maximum of ...
Assessing the CAM5 Physics Suite in the WRF-Chem Model : Implementation, Evaluation, and Resolution Sensitivity
Contributor:Ma, P.-L.; Rasch, P. J.; Fast, J. D.; Easter, R. C.; Gustafson, W. I., Jr.; Liu, Xiaohong; Ghan, S. J.; Singh, B.
A suite of physical parameterizations (deep and shallow convection, turbulent boundary layer, aerosols, cloud microphysics, and cloud fraction) from the global climate model Community Atmosphere Model version 5.1 (CAM5) ...
Evaluation of Collocated Measurements of Radar Reflectivity and Particle Sizes in Ice Clouds
Contributor:Pokharel, Binod; Vali, Gabor
Measured 94-GHz reflectivity in midlevel, stratiform ice clouds was compared with reflectivity calculated from size distributions determined with a particle imaging probe. The radar and the particle probe were carried on ...
Observation of Polar Stratospheric Clouds Over McMurdo (77.85°S, 166.67°E) (2006-2010)
Contributor:Di Liberto, L.; Cairo, F.; Fierli, F.; Di Donfrancesco, G.; Viterbini, M.; Deshler, Terry; Snels, M.
Polar stratospheric clouds (PSCs) have been observed in the Antarctic winter from 2006 to 2010 at the Antarctic base of McMurdo Station using a newly developed Rayleigh lidar. Total backscatter ratio and volume depolarization ...
Airborne Measurements of Coastal Jet Transition around Point Conception, California
Contributor:Rahn, David A.; Parish, Thomas R.; Leon, Dave
Low-level winds along the Californian coast during spring and early summer are typically strong and contained within the cool, well-mixed marine boundary layer (MBL). A temperature inversion separates the MBL from the ...
Ice Initiation by Aerosol Particles : Measured and Predicted Ice Nuclei Concentrations Versus Measured Ice Crystal Concentrations in an Orographic Wave Cloud
Contributor:Eidhammer, T.; DeMott, P. J.; Prenni, A. J.; Petters, M. D.; Twohy, C. H.; Rogers, D. C.; Stith, J.; Heymsfield, A.; Wang, Z.; Pratt, K. A.; Prather, K. A.; Murphy, Shane; Seinfeld, J. H.; Subramanian, R.; Kreidenweis, S. M.
The initiation of ice in an isolated orographic wave cloud was compared with expectations based on ice nucleating aerosol concentrations and with predictions from new ice nucleation parameterizations applied in a cloud ...
Aerosol Property Variations Over Global Oceans as Observed by the A-train Satellites
Contributor:Luo, Tao; Yuan, Renmin; Wang, Zhien; Zhanga, Damao
Satellite observations show large marine aerosol property variations over global oceans. With new A-train satellite measurements, this study explores processes controlling these aerosol variations. Results show that marine ...
Airborne Observations of a Catalina Eddy
Contributor:Parish, T. R.; Rahn, David A.; Leon, Dave
Summertime low-level winds over the ocean adjacent to the California coast are typically from the north, roughly parallel to the coastline. Past Point Conception the flow often turns eastward, thereby generating cyclonic ...
Calibration of the Passive Cavity Aerosol Spectrometer Probe for Airborne Determination of the Size Distribution
Contributor:Cai, Y.; Snider, Jefferson Robert; Wechsler, P.
This work describes calibration methods for the particle sizing and particle concentration systems of the passive cavity aerosol spectrometer probe (PCASP). Laboratory calibrations conducted over six years, in support of ...
