Modelled long-term wildfire occurrence probabilities in sagebrush-dominated ecosystems in the western US (1985 to 2019) Modelled long-term wildfire occurrence probabilities in sagebrush-dominated ecosystems in the western US (1985 to 2019)
Exotic annual grasses are one of the most damaging biological stressors in western North America and increase the susceptibility of landscapes to wildfire occurrence. Here we couple estimates of long-term rangeland component fractions (e.g. exotic annual grasses) with remote sensing, climate data, and machine learning techniques to estimate the long-term (1985 to 2019) probability of...
Historic and future trends in exotic annual grass (%) cover in the western US (1985 to 2019 and 2025 to 2040) Historic and future trends in exotic annual grass (%) cover in the western US (1985 to 2019 and 2025 to 2040)
Exotic annual grasses [EAG] are one of the most damaging biological stressors in western North America. Despite numerous environmental and societal impacts associated with EAG there remains a need to enhance regional monitoring capabilities to better guide management and conservation efforts. Here we provide estimates of historic and potential future trends in EAG abundance that were...
Probabilistic estimates of landscape change in Alaska (1984 to 2015) Probabilistic estimates of landscape change in Alaska (1984 to 2015)
Contemporary climate change in Alaska has resulted in amplified rates of press and pulse disturbances that drive ecosystem change with significant consequences for socio-environmental systems. Despite the vulnerability of Arctic and boreal landscapes to change, little has been done to characterize landscape change and associated drivers across northern high-latitude ecosystems. Here we
Vertical land motion rates for the years 2015 to 2023 - Coastal Alaska Vertical land motion rates for the years 2015 to 2023 - Coastal Alaska
Datasets contain vertical land motion (VLM) rates (land uplift and subsidence) derived from Sentinel-1 A/B satellites between 2015 and 2023 for the Alaska coastline. Files are available as csv files.
CoSMoS-AK Modeled flood and erosion hazards at Unalakleet - Coastal Alaska CoSMoS-AK Modeled flood and erosion hazards at Unalakleet - Coastal Alaska
This data release consists of flood hazard maps from compound coastal hazards--specifically sea-level rise (SLR) and projected coastal storms. Products include projected flood depths, flood extents including uncertainties, water elevations, wave heights, velocity hazard, and erosion and sedimentation pattern. These are generated using a suite of numerical models driven by outputs from...
Generated Burn Severity Offset Correction Values for a Composite Burn Index Field Plot Dataset Generated Burn Severity Offset Correction Values for a Composite Burn Index Field Plot Dataset
Phenological correction of pre- and post-fire imagery is used to improve remotely-sensed burn severity predictions by standardizing vegetation greenness between image pairs. However, the efficacy of existing methods across diverse fire conditions and scenarios remains underexplored. In this study, we evaluated the impact of phenological offset corrections across various methodological...
