Wildfire building destruction and exposure in the conterminous United States, 2002-2022 Wildfire building destruction and exposure in the conterminous United States, 2002-2022
Wildfires pose a major threat to human life and property, but there is limited information for assessing numbers or precise locations of building losses at a national scale. This geospatial dataset was developed to identify point locations of all buildings destroyed by or exposed to major wildfire disasters from 2002-2022. The data include all wildfire events in the conterminous United...
Land use and socioeconomic time-series reveal legacy of redlining on present-day gentrification within a growing United States city. Land use and socioeconomic time-series reveal legacy of redlining on present-day gentrification within a growing United States city.
Home Owners’ Loan Corporation (HOLC) maps illustrated patterns of segregation in United States cites in the 1930s. As the causes and drivers of demographic and land use segregation vary over years, these maps provide an important spatial lens in determining how patterns of segregation spatially and temporally developed during the course of the past century. Using a high-resolution land...
Integrating land use land cover change into future scenarios of electricity systems - Data Release Integrating land use land cover change into future scenarios of electricity systems - Data Release
Modeled projections for deep decarbonization require large amounts of solar energy, which may compete with other land uses such as agriculture, urbanization, and conservation of natural lands. Existing capacity expansion models do not integrate land use land cover change (LULC) dynamics into projections. We explored the interaction between projected LULC and solar photovoltaic (PV)...
Digital Data for Land and climate change in Mexico and Texas reveals small effects on migratory habitat of monarch butterflies (Danaus plexippus). Digital Data for Land and climate change in Mexico and Texas reveals small effects on migratory habitat of monarch butterflies (Danaus plexippus).
The decline of the iconic monarch butterfly in North America has motivated research on the impacts of land use and land cover (LULC) change and climate variability on monarch habitat and population dynamics. We investigated spring and fall trends in LULC, milkweed and nectar resources over a 20-year period, and ~30 years of climate variables in Mexico and Texas, a key region supporting...
United States Large-Scale Solar Photovoltaic Database (ver. 3.0, April 2025) United States Large-Scale Solar Photovoltaic Database (ver. 3.0, April 2025)
The United States Large-Scale Solar Photovoltaic Database (USPVDB) provides the locations and array boundaries of U.S. ground-mounted photovoltaic (PV) facilities with capacity of 1 megawatt or more. It includes corresponding PV facility information, including panel type, site type, and initial year of operation. The creation of this database was jointly funded by the U.S. Department of...
Wind turbine wakes can impact down-wind vegetation greenness Wind turbine wakes can impact down-wind vegetation greenness
Global wind energy has expanded 5-fold since 2010 and is predicted to expand another 8�10-fold over the next 30 years. Wakes generated by wind turbines can alter downwind microclimates and potentially downwind vegetation. However, the design of past studies has made it difficult to isolate the impact of wake effects on vegetation from land cover change. We used hourly wind data to model...

The rise of U.S. photovoltaics: An exploration of land use density trends in large-scale solar facility attributes, 2012-2021 The rise of U.S. photovoltaics: An exploration of land use density trends in large-scale solar facility attributes, 2012-2021
An energy transition is underway in the United States; renewable energy generation is now on par with coal and nuclear generation. The number of large-scale solar photovoltaic facilities increased approximately tenfold between 2012 and 2021, with an associated 25-fold increase in cumulative installed capacity. With ambitious decarbonization and renewable energy deployment goals at both...

Georectified polygon database of ground-mounted large-scale solar photovoltaic sites in the United States Georectified polygon database of ground-mounted large-scale solar photovoltaic sites in the United States
Over 4,400 large-scale solar photovoltaic (LSPV) facilities operate in the United States as of December 2021, representing more than 60 gigawatts of electric energy capacity. Of these, over 3,900 are ground-mounted LSPV facilities with capacities of 1 MWdc or more. Ground mounted LSPV installations continue increasing, with more than 400 projects appearing online in 2021 alone; however...
