Jessica Sutton (617/UMBC) is the Principal Investigator on the proposal "Identification of Virga Precipitation Events," which was among the proposals selected in 2025 for UMBC CIDER funding. Her Co-Investigators are
Thomas Stanley (617/UMBC) and
Tejas Gokhale (Computer Science and Electrical Engineering/UMBC).
UMBC's
Center and Institute Departmentally-Engaged Research (CIDER) program's goal "includes supporting and promoting collaborative research between scholars based in one of UMBC’s affiliate centers and institutes and the university’s faculty researchers. Selected proposals are awarded up to $50,000 in seed funding for 18 months."
Dr. Sutton shared their project summary:
"Determining the causes of false detections from satellite-derived precipitation is of utmost importance due to the development and dependence of precipitation estimates in global water cycle modeling, weather forecasting, flood modeling, landslide hazard assessment, drought monitoring, watershed modeling, and climate modeling. One kind of false detection that needs to be addressed is virga or “dry precipitation events”. They are described as “dry precipitation events” because they are considered precipitation events that occur higher in the atmosphere but evaporate before reaching the surface. This means that every satellite-based precipitation product is affected by virga because of the way in which precipitation is derived from satellite remote sensors. Satellite-based precipitation estimates are derived from cloud temperatures, emission-based retrievals, and/or scattering-based retrievals. Regardless of whether satellite-based precipitation estimates are derived from VIS/IR, passive microwave, or both, they are derived from measurements within the atmosphere and not at the surface. As a result, any analysis or model that uses satellite-based precipitation as inputs is problematic.
The purpose of this collaboration is to (1) complete a proof-of-concept project to identify virga events using vertical profiles from ground radar and (2) apply for a National Science Foundation (NSF) grant to support future work. The proof of concept will include collection of a database of virga events at one radar ground station and building a machine learning tool for flagging virga events. The NSF grant will seek to determine the influence that virga precipitation has on global precipitation datasets and climate modeling."

GESTAR II Seminar Series, Thursday, May 8th, 11:00am
Join us for a virtual seminar by
Dr. Skylar Bayer, NOAA Fisheries Alaska Regional Office. Her talk is titled "Alaska Regional Office Habitat Conservation Division: Essential Fish Habitat Science and Management."
Date and Time: Thursday, May 8, 2025 at 11:00am EST
Abstract:
"NOAA Fisheries Alaska Regional Office (AKRO) Habitat Conservation Division (HCD) is responsible for identifying and conserving essential fish habitat (EFH) as mandated by the Magnuson-Stevens Fishery Conservation and Management Act. Our habitat conservation activities include protecting EFH, mitigating damage to and enhancing habitat affected by hydropower project construction and operations, removing invasive species, and restoring habitat that has been affected by development, oil spills, and other human activities. We focus on habitats used by federally-managed fish species located offshore, nearshore, in estuaries, and in freshwater areas important to migratory salmon. This presentation will primarily highlight our EFH databases and their applied use in the fishery management council process and consultations."

Spotlight on Landslide and Glacier Research by both Stanley and Ultee
While one may not think about greenhouse gases and landslides in the same context, the
2024 paper “Landslide Hazard Is Projected to Increase Across High Mountain Asia” led by
Thomas Stanley (617/UMBC) explored the link. Published in
Earth’s Future, this study was the focus of the National Snow and Ice Data Center
(NSIDC) Spotlight “Rising risks of sliding slopes in High Mountain Asia” in early 2025.
One key question in the Spotlight article was “As climate shifts, likely weather patterns change, but by how much?” In turn, “The answer depends largely on human actions.” They discuss which factors Stanley’s team used to create “the landslide hazard indicator (LHI),” and one of the factors is SSPs (Shared Socioeconomic Pathways), “which group projections about emissions [which increase in relation to levels of fossil fuels] and mitigation efforts.” Given High Mountain Asia's (HMA) varied terrain and elevation, “Stanley and coauthors emphasized “the need for continued vigilance by engineers, planners, and emergency responders across High Mountain Asia.”” Consider the catastrophic effects of “the late-monsoon rainfall in late September 2024, which resulted in 100+ landslides across Nepal and overall 200+ deaths.” For further supplemental information, the research team released a
data set, available through the NSIDC DAAC.

The article “Inter-model differences in 21st century glacier runoff for the world's major river basins,” of which
Lizz Ultee (615/MSU) is second author, was selected as an
Editor’s Highlight in The Cryosphere. The first author, Finn Wimberly, was working with her as an undergraduate research assistant. Dr. Ultee stated, “This study is the first comparison of glacier runoff to the world’s 75 major river basins, as simulated by three global glacier models.” These models are “the Global Glacier Evolution Model (GloGEM), Open Global Glacier Model (OGGM), and Python Glacier Evolution Model (PyGEM).” In discussing their challenge, methods, and goals, “uncertainties in projected glacier runoff from a multi-glacier-model ensemble have yet to be quantified. Here, we analyze the first estimate of glacier runoff projections for the three most advanced, globally capable glacier models, forced by an ensemble of CMIP6 GCMs and Shared Socioeconomic Pathways (SSPs), for 75 glaciated major river basins. For each basin, we analyze annual glacier runoff, the year of peak water, and seasonal runoff cycle projected by each glacier evolution model until the year 2100. [...] Ultimately, the study aims to summarize inter-model similarities and differences in runoff projections, discern general reasons for observed differences, and provide guidance for [those] seeking to incorporate readily available glacier model projections into future planning.”

Join us for a virtual seminar by
Dr. Lyatt Jaeglé, Dept. of Atmospheric and Climate Science (University of Washington). Her talk is titled "Blowing snow over Arctic sea ice: Integrating modeling, field measurements, and satellite observations."
Date and Time: Thursday, April 10, 2025 at 11:00am EST
Abstract:
"Blowing snow sublimation over Arctic sea ice is an important but under-constrained source of wintertime sea salt aerosol (SSA) and reactive halogens, with implications for polar tropospheric chemistry, cloud microphysics, and radiative forcing. In addition to influencing atmospheric composition, blowing snow sublimation removes snow from the surface, reducing snow accumulation on sea ice and modifying the surface energy budget. I will summarize our past work using chemical transport modeling to quantify blowing snow sublimation and its role as a source of SSA. I will then highlight on-going work using observations from the ICESat-2 satellite to provide new constraints on the frequency, extent, and sublimation fluxes of blowing snow over Arctic sea ice. Comparisons with MOSAiC in situ observations and SnowModel-LG simulations demonstrate the capability of ICESat-2 to map the spatial and temporal variability of blowing snow sublimation. These findings help bridge observational gaps and refine our understanding of the Arctic snow and atmospheric moisture budgets in a rapidly changing environment."
