Creating Wildfire-Resilient Communities in Utah: Fuel Treatments in the Wildland-Urban Interface
No full textIn the western United States, decades of wildfire suppression and grazing have led to changes in the amount and type of wildland fuels. In many lower montane forests, fuels such as logs, dead trees, and fallen leaves have accumulated. In many sagebrush-dominated rangelands, annual grasses have invaded, and pinyon pine and juniper woodlands have encroached. These areas now threaten to burn at uncharacteristically high fire severity, a metric based on how much vegetation is killed. Climate change and rapid population growth have exacerbated this issue in Utah, increasing the threat wildfire poses to the state’s communities, infrastructure, and ecosystems. Fuel treatments have been shown to effectively lower fire severity and can reduce wildfire risk in Utah’s wildland-urban interface (WUI), where flammable wildlands border homes and buildings. Here, we review common impacts and risks of wildfire, the current state of fuel treatments in Utah, and how homeowners can protect their property
Libera Radiometric Ground Calibration in the Earth Radiance Facility (ERF)
No full textLibera is a next generation Earth-viewing scanning radiometer that will fly on the Joint Polar Satellite System-4 (JPSS-4), which is set to launch in 2027. Libera will provide continuity of Earth radiation budget measurements from the Clouds and Earth’s Radiant Energy System (CERES), enhance observing capabilities to support Earth radiation budget science goals and advance the development of self-contained observing systems. Libera measurements will be collected in four spectral channels: the shortwave channel [SW; (0.3 to 5) µm] to measure solar radiation reflected by the Earth, the longwave channel [LW; (5 to 50) µm] to measure the Earth thermal emission, split short-wave channel [SSW; (0.7 to 5) µm] to further quantify the shortwave energy deposition in the Earth system, and the total channel [TOT; (0.3 to 100+) µm] to measure the total radiation reflected and emitted by the Earth system.
Libera has undergone primary radiometric ground calibration at laser tie points from 0.260 µm to 15.5 µm in the Earth Radiance Facility (ERF) at LASP. Over 600 calibration data sets have been collected with the flight telescopes and detectors in ERF. ERF utilizes a tunable optical parametric amplifier (OPA) laser source to generate in-vacuum narrow band uniform radiance levels ≥ 100 W/m^2/sr for a large portion of the laser spectrum and ≥ 500 W/m^2/sr for much of the visible/NIR range. The absolute spectral response of the Libera science radiometers is set by comparison to the Planar Bolometric Radiometer for Radiance (PBR-R) standard reference detector.
This presentation will include a description of ERF, PBR-R, and the calibration methodology along with preliminary calibration results for the Libera science radiometers from the UV to MIR
Stainless-Steel Piano Key Weir
No full textThe spillway of the Oule dam (Pyrénées, France) was successfully modified and uprated in 2018. Its discharge capacity has been increased in accordance with the updated hydrological analysis and French regulations. In order to achieve a significant increase of the total discharge capacity, the dam operator (Société Hydroélectrique du Midi - ENGIE) has re-designed the whole spillway. A 1 m high type-A piano key weir solution was selected and implemented to replace the existing ogee crest. This solution is unique since it is made of stainless steel, precast, transported by helicopter on site and assembled by bolting. This paper focuses on the design and the building method which required to be adapted to the complex geometry of the structure and the site constraints. Information about the design assumptions and the installation are also presented (on-site works procedure and duration, costs)

Cloud Seeding: Enhancing Winter Snowpack to Bolster Utah\u27s Water Supply
No full textAs Utah’s climate warms, the state is working to combat the decline in winter snowpack caused by rising temperatures. Cloud seeding is a safe technology that, under the right conditions, can boost snowfall. In this fact sheet, we describe what cloud seeding is, where it is currently used in Utah, and the safety measures and management practices that ensure its responsible use

A Preliminary, Photography-Based Assessment of Bee Diversity at the Finca Botánica Organic Farm in the Central Pacific Coast of Ecuador
No full textUnderstanding wild bee diversity is critical for pollinator conservation, particularly in understudied tropical regions like coastal Ecuador. This preliminary study provides a photography-based assessment of bee diversity at Finca Botánica, an organic and regenerative farm on Ecuador’s central Pacific coast. Over a 10-day survey in December 2024, researchers documented 51 bee species across four families, with Apidae being the most represented. The study highlights a predominance of solitary, ground-nesting bees and a lower-than-expected diversity of Meliponini (stingless bees) and Euglossini (orchid bees) compared to other regions of Ecuador. Many species were found in forest patches, ecological corridors, and cover-cropped maize fields, underscoring the role of sustainable farming practices in supporting pollinator diversity. While photographic methods provided valuable preliminary data, they also revealed limitations in species-level identification, reinforcing the need for future specimen-based surveys. These findings suggest that Ecuador’s dry coastal forests may harbor a richer bee community than previously recognized and that organic farms can serve as important refuges for native pollinators
An Empirical Investigation of the Effects of Gunshot Detection Technology in Detroit
No full textThis paper evaluates the impact of acoustic gunshot detection technology (GDT) on crime and policing outcomes in Detroit, Michigan. Leveraging the implementation of ShotSpotter across high-crime neighborhoods, I analyze outcomes including crime rates, emergency calls, police response times, and case clearance. My findings indicate that ShotSpotter installation is associated with a 6% reduction in violent crime but a modest increase in nonviolent crime. The technology also produces a large increase in the reporting of gunfire incidents—over 300% more gunshot-related calls for service—yet police respond 7% slower to ShotSpotter alerts than to citizen-reported gunshots. Consistent with prior research, I find no significant change in case clearance rates. Taken together, the results highlight both the benefits and limitations of GDT: it appears to reduce violent crime and improve detection but imposes significant operational costs in terms of call volume and response efficiency. These findings underscore the need for careful cost-benefit analysis when municipalities consider adopting such technologies, as the net impact depends on both public safety gains and resource trade-offs in already stretched police departments
