Increasing model spatial resolution fails to reduce simulated storm biases
21 January 2025
Fast, Jerome D
Supported by:
Research area: Cloud-Aerosol-Precipitation Interactions
Accurately predicting impacts from storms depends on accurately simulating their growth as a function of atmospheric conditions. Using a model setup like those used for operational forecasting, results show that total storm rainfall over a large area is reasonably predicted. However, heavy rain rates were too frequent and light rain [...]
New methods for extracting more detail from existing data sets
21 January 2025
Isaacman-VanWertz, Gabriel
Supported by:
Research area: Aerosol Properties
Detailed data of what is in the atmosphere is often very complex, containing thousands of chemicals without known identities or properties. By developing new automated tools for analyzing certain types of data, this research will substantially improve the ability to make sense of these data and extract new details about the composition of [...]
Bridging the data gap in Southern Hemisphere aerosol research
17 January 2025
Fast, Jerome D
Supported by:
Research area: Aerosol Processes
Aerosols are known to affect cloud properties, including their formation, growth, and precipitation, which in turn influences climate over long time scales. Aerosol-cloud-interactions (ACI) depend on how their properties change together, yet few measurements capture this variability, especially in the presence of convective cloud populations that can be observed routinely [...]
Revealing atmospheric secrets with advanced airborne data
16 January 2025
Mei, Fan
Supported by:
Research area: Cloud-Aerosol-Precipitation Interactions
This research addressed the challenge of using extensive, complex airborne field campaign data from the Atmospheric Radiation Measurement (ARM) user facility's Data Center to study the Earth's atmosphere more effectively. By standardizing these data into a single, easily accessible format, it simplifies data management and enables more detailed atmospheric studies. [...]
Storm width dictates which atmospheric properties control storm depth
16 January 2025
Fast, Jerome D
Supported by:
Research area: Cloud Distributions/Characterizations
Storms are a primary mechanism for transporting atmospheric properties, such as trace gases, aerosols, moisture, heat, and momentum, that significantly impact weather and climate. Where these constituents are transported is modulated by storm depth; therefore, accurate prediction of this parameter affects the subsequent ability to accurately predict weather and climate. [...]
