Development of small uncrewed aerial systems for multi-instrument geophysical data acquisition in active geothermal systems Development of small uncrewed aerial systems for multi-instrument geophysical data acquisition in active geothermal systems
Small Uncrewed Aerial Systems (sUAS) serve as critical platforms for geophysical data collection at an intermediate scale between lower resolution, regional datasets collected via crewed aerial surveys, and high resolution, but spatially sparse sampling of ground-based data collection methods. Advances in sensor design and sUAS capabilities have led to rapid advances in the amount and...

Opera Dynamic Surface Water extents for Harmonized Landsat Sentinel-2 (DSWX-HLS) validation activities Opera Dynamic Surface Water extents for Harmonized Landsat Sentinel-2 (DSWX-HLS) validation activities
We present the validation methodology and results of Dynamic Surface Water eXtent from Harmonized Landsat Sentinel-2 (DSWx-HLS). The DSWx-HLS product is the first of the DSWx suite, comprised of products each which map water from Earth Observation optical and SAR satellites. We detail the generation of high-resolution (3 m) validation datasets from a globally-stratified sample of dry...

Monitoring long-term changes of urban surface temperature using time-series land cover and remote sensing data across 50 major cities in the United States Monitoring long-term changes of urban surface temperature using time-series land cover and remote sensing data across 50 major cities in the United States
The increase of developed land changes the Earth’s ecosystems and, in doing so, impacts the natural environment and further affects the services it provides to humans. Urban growth and associated land cover transitions alter the thermal and physical properties of the land surface, resulting in surface temperature change in urban areas. In this study, we integrated both land cover and...

Mapping the Surface Urban Heat Island effect using the Landsat Surface Temperature Product Mapping the Surface Urban Heat Island effect using the Landsat Surface Temperature Product
Urban development and associated land cover and land use change alter the thermal, hydrological, and physical properties of the land surface. Urban areas usually exhibit relatively warmer air and surface temperatures than surrounding non-urban lands, a phenomenon recognized as Surface Urban Heat Island (SUHI). As urban areas continue to develop and the climate continues to warm, it has...

Assessing snowpack stratigraphy accuracy based on different input data: Insights for operations avalanche forecasting Assessing snowpack stratigraphy accuracy based on different input data: Insights for operations avalanche forecasting
Avalanche forecasters and snow scientists use physically based snow stratigraphy models to fill spatial and temporal gaps in field-based snow profile observations. These models generate stratigraphy predictions using meteorological input from automated weather stations (AWS) or numerical weather prediction (NWP) models. The choice of input data is often determined by data availability or

Comparing snowpack meteorological inputs to support regional wet snow avalanche forecasting Comparing snowpack meteorological inputs to support regional wet snow avalanche forecasting
Wet snow avalanches are predicted to increase in frequency with climate change and are often difficult to forecast. Improving our understanding of wet snow avalanche timing will help with current forecasting challenges. The onset of wet snow avalanching is closely tied to the temporal progression of liquid water flow through the seasonal snowpack. Measuring the flow of water through the...
