Chemical Characterization of Aerosols on the East Coast of the United States Using Aircraft and Ground-Based Stations during the CLAMS Experiment
(American Meteorological Society, 2005)The Chesapeake Lighthouse and Aircraft Measurements for Satellites (CLAMS) experiment was carried out off the central East Coast of the United States in July 2001. During CLAMS, aerosol particle mass was measured at two ... -
Two MODIS Aerosol Products over Ocean on the Terra and Aqua CERES SSF Datasets
(American Meteorological Society, 2005)Understanding the impact of aerosols on the earth?s radiation budget and the long-term climate record requires consistent measurements of aerosol properties and radiative fluxes. The Clouds and the Earth?s Radiant Energy ... -
A Parameterization of the Effective Layer Emission for Infrared Radiation Calculations
(American Meteorological Society, 2005)The impact of the vertical integration of radiative transfer on cooling rate calculations is studied for different numerical schemes. One involves the effective emitting temperature of a layer (scheme A), and the other ... -
Effects of Moist Froude Number and CAPE on a Conditionally Unstable Flow over a Mesoscale Mountain Ridge
