An evaluation of a severe smog episode in the Eastern U.S. using regional modeling and satellite measurements
(2011)
An ensemble of regional chemical modeling (WRF/Chem with RADM2) simulations, satellite, ozonesonde, and surface observations during July 7-11, 2007 was used to examine the horizontal and vertical signature of one of the ...
RADIATIVE FLUXES AND ALBEDO FEEDBACK IN POLAR REGIONS
(2011)
The Arctic is experiencing an unprecedented increase in surface temperature and decrease in sea ice extent. Discussion as to the causes that contribute to the Arctic warming is still ongoing. The ice-albedo feedback has ...
IMPACTS OF FAIR-WEATHER CUMULUS CLOUDS, BAY BREEZES, AND LAND USE ON URBAN AIR QUALITY AND CLIMATE
(2011)
Fair-weather cumulus clouds, bay breezes, and land use influence air quality and climate. The impacts of urban land surface changes and model resolution on fair-weather cumulus clouds, bay breezes, air quality, and climate ...
Investigating Aerosol Effects on Clouds, Precipitation and Regional Climate in US and China by Means of Ground-based and Satellite Observations and a Global Climate Model
(2011)
Aerosols affect climate by scattering/absorbing radiation and by acting as cloud condensation nuclei (CCN) or ice nuclei (IN). One of the least understood but most significant aspects of climate change is the aerosol effect ...
Simulated Dust Aerosol Lifecycle in the NASA GEOS-5 Atmospheric Transport Model and Sensitivity to Source and Sink Mechanisms
(2011)
Understanding interactions of mineral dust aerosols with the Earth system remains a key uncertainty in assessing global climate change. A significant portion of this uncertainty arises due to an incomplete understanding ...
Mars Weather and Predictability: Modeling and Ensemble Data Assimilation of Spacecraft Observations
(2011)
Combining the perspectives of spacecraft observations and the GFDL Mars General Circulation Model (MGCM) in the framework of ensemble data assimilation leads to an improved understanding of the weather and climate of Mars ...
Strategies for Coupling Global and Limited-Area Ensemble Kalman Filter Assimilation
(2011)
This thesis compares the forecast performance of four strategies for coupling
global and limited area data assimilation: three strategies propagate information
from the global to the limited area process, while the fourth ...
Towards Understanding Key Processes Affecting Heat and Salinity Balance in the Global Ocean
(2011)
Ocean heat content is compared among nine analyses of global ocean temperature during 1960-2002. Two are independent of numerical modeling, and the rest rely on data assimilation, which utilizes an ocean general circulation ...
