Atmospheric Conditions Preceeding Very Rapid Sea Ice Loss Events
(2019)
Even though the observed amplified warming trend in the Arctic region is well-established in theory through climate feedbacks and reproduced in global climate model projections, the same global climate models underestimate ...
A Tale of Two Mesovortices: Analysis of a Simulated Severe MCS Observed By PECAN on 5-6 July 2015
(2017-07)
Understanding and forecasting nocturnal thunderstorms and their hazards remain elusive goals. To this end, an expansive array of fixed and mobile observing systems were deployed in the summer of 2015 for the Plains Elevated ...
Spatiotemporal gap-filling of NASA Deep Blue aerosol optical depth over CONUS using the UNet 3+ architecture
(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 ...
Explainable Frontal Boundary Predictions for Applications in Operational Environments
(2024-05-10)
Frontal boundaries drive many high-impact weather events around the globe. Identifying fronts through various thermodynamic fields increases predictability of hazardous weather phenomena. Frontal analysis is still primarily ...
Impacts of Multiscale Predictors on Random Forest Based Probabilistic Forecasts of Severe Weather Hazards
(2024-05-10)
Machine learning (ML) algorithms utilized for post-processing of convection-allowing model/ensemble (CAM/CAE) output has been a major area of research to handle limitations with CAM/CAE forecasts. ML has been used to correct ...
Subgrid Scale Modeling of Turbulence and Cloud Microphysics Interactions
(2024-08-01)
Clouds have a significant but uncertain impact on Earth's climatological and hydrological cycles. In particular, the warm rain process has considerable inconsistencies between current theories and observations. One hypothesis ...
Examining the Characteristics and Evolution of Temperature Whiplash Events in the US Southern Plains
(2024-08-01)
Rapid extreme temperature swings, termed “temperature whiplashes”, can lead to significant and intense socioeconomic impacts. Few studies have considered tem- perature whiplashes over global, continental, or other large ...
OPTIMIZATION AND VALIDATION OF MAIA AEROSOL RETRIEVAL USING POLDER OBSERVATIONS
(2024-08-01)
NASA’s Multi-Angle Imager for Aerosols (MAIA) is a satellite-borne multi-angle polarimeter (MAP) instrument that aims to investigate the human health effects caused by exposures to various types of particulate matter (PM) ...
