Carbon-Based Pollutant Analysis and Remote Sensor Validation Using Column-Observing Fourier Transform Infrared (FTIR) Spectrometers During the TRACER Campaign
Spicer, Elizabeth (2023-08-04)Greenhouse gases methane (CH4), and carbon dioxide (CO2), along with carbon monoxide (CO), while produced by both anthropogenic and natural sources, all contribute to atmospheric warming. Additionally, CO poses health risks ... -
A correlation-based Inversion Method for Aerosol Property (CIMAP) Retrieval from AERONET Measurements
Huang, Taozhong (2021-08-05)We developed a principal-component based inversion approach – A correlation-based Inversion Method for Aerosol Property (CIMAP), to retrieve aerosol properties from AERONET measurements of aerosol optical depths (AODs) and ... -
Drop Size Distribution Retrieval from Radar Data to Enhance the Spectral Bin Classification in Detecting Icing Conditions
Lis, Nathan (2020-07-31)The emerging Federal Aviation Administration (FAA) restrictions on flight into and out of terminal airspaces (TASs) require discrimination between freezing rain, freezing drizzle, and other forms of winter precipitation ... -
Examining CERES Downward Shortwave Surface Radiative Flux Measurements in the Context of Oklahoma Mesonet Measurements in 2019-2021
Lamkin, Bradley (2023-08-04)The surface radiation budget affects different components of Earth’s climate system. Accurate assessments of the surface radiation budget help improve climate forecasts, such as drought prediction. In addition, short-term ... -
Improving Drop Size Distribution Retrieval and Rain Estimation from Polarimetric Radar Data using the Deep Neural Network
Ho, Junho (2022-08)Drop size distribution (DSD) and rain rate (R) have been estimated from polarimetric radar data are now available nationwide. DSD and R are essential in understanding rain microphysics. Past studies utilized parametrized ... -
Information content analysis of combined lidar-polarimeter retrievals to improve aerosol remote sensing accuracy
Nowicki, David (2021)Aerosols are small particles suspended in the atmosphere which affect global climate change via scattering and absorbing sunlight and serving as cloud condensation nuclei. Moreover, the prevalence of some anthropogenic and ... -
Non-Terminal Hydrometeor Fall Speed Effects on Modeled Rain Processes
Roy, Logan (2023-08-04)Recent observational studies have shown hydrometeors exhibit non-terminal fall speeds. The goal of this study is to understand how these non-terminal fall speeds affect the collision, coalescence and breakup of raindrops ... -
Relationships Between Lidar Aerosol Extinction and Backscatter Coefficients with CCN Number Concentrations in the Southeast Atlantic
Lenhardt, Emily (2021-08-05)Due to seasonal biomass burning and the presence of a semi-permanent stratocumulus deck off the western coast of Africa, the Southeast Atlantic (SEA) region is particularly important in terms of characterizing aerosol and ... -
Spatiotemporal gap-filling of NASA Deep Blue aerosol optical depth over CONUS using the UNet 3+ architecture
Lee, Jeffrey (2024-05-10)Due to sensor and algorithmic constraints, satellite aerosol optical depth (AOD) retrievals are spatially incomplete over clouds, deserts, and other bright surfaces. These gaps in satellite AOD datasets represent a significant ... -
Subseasonal Variability of Biomass Burning Aerosol Radiative Properties Retrieved by 4STAR during the ORACLES 2016-2018 Campaigns
Mitchell, Logan (2022-05)Absorbing aerosols play a role in cloud and radiation processes, but these interactions are complex and have a high degree of uncertainty. The interactions of Biomass Burning (BB) aerosols with the semipermanent subtropical ...
