Identification and Quantification of Regional Aerosol Trends and Impact on Clouds over the North Atlantic Ocean
(2017)
Aerosols and clouds contribute to atmospheric variability and Earth’s radiative balance across local, regional, and global scales. Originating from both natural and anthropogenic sources, aerosols can cause adverse health ...
Satellite Retrieval of Updrafts and Cloud Condensation Nuclei Concentrations at Cloud Bases
(2017)
Aerosol-cloud-climate interactions are the largest uncertainty in climate forcing. Narrowing down the uncertainties of the aerosol impact on Earth’s climate ultimately requires concurrent global measurements of aerosol, ...
IMPROVED SATELLITE MICROWAVE RETRIEVALS AND THEIR INCORPORATION INTO A SIMPLIFIED 4D-VAR VORTEX INITIALIZATION USING ADJOINT TECHNIQUES
(2017)
Microwave instruments provide unique radiance measurements for observing surface properties and vertical atmosphere profiles in almost all weather conditions except for heavy precipitation. The Advanced Microwave Scanning ...
Multi-instrument approach for measuring spectral aerosol absorption properties in UV and VIS wavelengths
(2017)
The spectral dependence of light absorption by atmospheric particulate matter (PM) has major implications for air quality, surface ultraviolet (UV) radiation, and tropospheric oxidation capacity, but remains highly uncertain. ...
IMPACT OF AEROSOL DIRECT AND INDIRECT EFFECTS ON EAST ASIAN AIR QUALITY DURING EAST-AIRE CAMPAIGN PERIOD
(2017)
WRF-Chem simulations were performed for the March 2005 East Asian Studies of Tropospheric Aerosols: an International Regional Experiment (EAST-AIRE) Intensive Observation Campaign (IOC) to investigate the effects of aerosols ...
An Investigation of the Parameterized Prediction of Lightning in Cloud-Resolved Convection and the Resulting Chemistry
(2017)
The Deep Convective Clouds and Chemistry (DC3) field campaign provided a unique set of observations to further investigate the role lightning and lightning-generated nitrogen oxides (LNOx) have on the composition of the ...
Multivariate Correlations: Balance Operators and Variable Localization in Ensemble Data Assimilation
(2017)
Localization is performed in ensemble data assimilation schemes to eliminate correlations that are contaminated by sampling error. This method is frequently necessary within numerical weather prediction (NWP) applications ...
ESTIMATING SURFACE ELEVATION BIASES FROM SUBSURFACE SCATTERED PHOTONS FOR LASER ALTIMETERS
(2017)
Three decades of satellite observations have revealed rapid changes in Earth’s cryosphere associated with anthropogenic climate change, including decreased extent and volume of Arctic sea ice, mass loss from the Greenland ...
