On Factors Controlling Marine Boundary Layer Aerosol Optical Depth
Author(s):Luo, Tao; Yuan, Renmin; Wang, Zhien
Sea spray aerosol is one of the largest natural contributors to the global aerosol loading and thus plays an important role in the global radiative budget through both direct and indirect effects. Previous studies have ...
Implementation of the Chemistry Module MECCA (v2.5) in the Modal Aerosol Version of the Community Atmosphere Model component (v3.6.33) of the Community Earth System Model
Author(s):Long, M. S.; Keene, W. C.; Easter, R.; Sander, R.; Kerkweg, A.; Erickson, D.; Liu, Xiaohong; Ghan, S.
A coupled atmospheric chemistry and climate system model was developed using the modal aerosol version of the National Center for Atmospheric Research Community Atmosphere Model (modal-CAM; v3.6.33) and the Max Planck ...
Aerosol First Indirect Effects on Non-Precipitating Low-Level Liquid Cloud Properties as Simulated by CAM5 at ARM Sites
Author(s):Zhao, C.; Klein, S. A.; Xie, S.; Liu, Xiaohong; Boyle, J. S.; Zhang, Y.
We quantitatively examine the aerosol first indirect effects (FIE) for non-precipitating low-level single-layer liquid phase clouds simulated by the Community Atmospheric Model version 5 (CAM5) running in the weather ...
Evaluating WRF-Chem Aerosol Indirect Effects in Southeast Pacific Marine Stratocumulus during VOCALS-REx
Author(s):Saide, P. E.; Spak, S. N.; Carmichael, G. R.; Mena-Carrasco, M. A.; Yang, Q.; Howell, S.; Leon, D. C.; Snider, Jefferson Robert; Bandy, A. R.; Collett, J. L.; Benedict, K. B.; de Szoeke, S. P.; Hawkins, L. N.; Allen, G.; Crawford, I.; Crosier, J.; Springston, S. R.
We evaluate a regional-scale simulation with the WRF-Chem model for the VAMOS (Variability of the American Monsoon Systems) Ocean-Cloud-Atmosphere-Land Study Regional Experiment (VOCALS-REx), which sampled the Southeast ...
Evaluating Winter Orographic Cloud Seeding : Design of the Wyoming Weather Modification Pilot Project (WWMPP)
Author(s):Breed, D.; Rasmussen, R.; Weeks, C.; Boe, B.; Deshler, Terry
An overview of the Wyoming Weather Modification Pilot Project (WWMPP) is presented. This project, funded by the State of Wyoming, is designed to evaluate the effectiveness of cloud seeding with silver iodide in the Medicine ...
Dryline in Southeast Wyoming. Part II : Airborne In Situ and Raman LiDAR Observations, A
Author(s):Bergmaier, Philip T.; Geerts, Bart; Wang, Zhien; Liu, Bo; Campbell, Patrick C.
Part I of this study describes the mesoscale structure of a dryline over southeastern Wyoming. This dryline formed just east of the western rim of the high plains on 22 June 2010 and became more defined as it progressed ...
Condensation Nuclei Measurements in the Midlatitude (1982-2012) and Antarctic (1986-2010) Stratosphere between 20 and 35 km
Author(s):Campbell, P.; Deshler, Terry
Balloon-borne stratospheric condensation nuclei (CN) measurements have been made from McMurdo Station, Antarctica (78°S), 1986-2010, and from Laramie, Wyoming (41°N), 1982 to the present. In the Antarctic region, the ...
Radiative Impact of Mineral Dust on Monsoon Precipitation Variability Over West Africa
Author(s):Zhao, C.; Liu, Xiaohong; Leung, L. R.; Hagos, S.
The radiative forcing of dust and its impact on precipitation over the West Africa monsoon (WAM) region is simulated using a coupled meteorology and aerosol/chemistry model (WRF-Chem). During the monsoon season, dust is a ...
Comparison of measured and calculated scattering from surface aerosols with an average, a size-dependent, and a time-dependent refractive index
Author(s):Cai, Yong; Montague, Derek C.; Deshler, Terry
Mid-continental surface aerosols have been measured at a small, minimally polluted city in summer and winter and on a nearby remote mountain in summer. Aerosol scattering, absorption, size distribution, and composition ...
Seasonal Variations of Antarctic Clouds Observed by CloudSat and CALIPSO Satellites
Author(s):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 ...
