Phenology pattern data indicating recovery trajectories of ponderosa pine forests after high-severity fires Phenology pattern data indicating recovery trajectories of ponderosa pine forests after high-severity fires
This tabular, machine-readable CSV file contains annual phenometrics at locations in ponderosa pine ecosystems across Arizona and New Mexico that experienced stand-clearing, high-severity fire. The locations represent areas of vegetative recovery towards pre-fire (coniferous/pine) vegetation communities or towards novel grassland, shrubland, or deciduous replacements. Each sampled area...
Mapped fire perimeters from the Sky Island Mountains of US and Mexico: 1985-2011 Mapped fire perimeters from the Sky Island Mountains of US and Mexico: 1985-2011
Polygon locations of fire perimeters in the Sky Island mountain ranges in the Madrean Archipelago Ecoregion of the southwestern United States and northern Mexico. These fires occurred from 1985 to 2011 and were mapped using Landsat satellite imagery.
Datasets for analyzing stream gage discharge and Landsat imagery integration in the greater Central Valley, California from 1984 to 2015 Datasets for analyzing stream gage discharge and Landsat imagery integration in the greater Central Valley, California from 1984 to 2015
This data release comprises the data files and code necessary to perform all analyses presented in the associated publication. The *.csv data files are aggregations of water extent on the basis of the European Commission's Joint Research Centre (JRC) Monthly Water History database (v1.0) and the Dynamic Surface Water Extent (DSWE) algorithm. The shapefile dataset contains the study area...
Prism Engine software source code v2.0.0 Prism Engine software source code v2.0.0
A continually increasing number of high-quality digital strong-motion records from stations of the National Strong Motion Project (NSMP) of the U.S. Geological Survey (USGS), as well as data from regional seismic networks within the U.S., called for automated processing of strong-motion records with human review limited to selected significant or flagged records. This PRISM (Processing...
Projections of Future Water Demand for the Western USA Projections of Future Water Demand for the Western USA
This data release contains projections of future water demand for the Western USA at the county level. This data is part of the project "Changes to Watershed Vulnerability under Future Climates, Fire Regimes, and Population Pressures" (https://www.sciencebase.gov/catalog/item/531dc54de4b04cb293ee7806), and is the product of an analysis that determined where populations are changing, and...
Vegetation Survey of the San Carlos Apache Reservation, Arizona and Surrounding Area (September to November 2017). Vegetation Survey of the San Carlos Apache Reservation, Arizona and Surrounding Area (September to November 2017).
This zip file contains spatial, descriptive and digital camera image data for a vegetation field dataset collected on the San Carlos Apache Reservation and surrounding area in Arizona, and used for analysis in the associated publication. Data consists of vector point data, vegetation community type, field observations, and digital camera images that correspond with the images in the...
Wetland Moist Soil Seed Maps for the Central Valley of California 2007-2017 Wetland Moist Soil Seed Maps for the Central Valley of California 2007-2017
We produced a series of maps of moist soil seed plants within managed wetlands in the Central Valley of California from 2007-2011 & 2013-2017. Moist soil seed plants, such as swamp timothy (Crypsis schoenoides) and watergrass (Echinochloa crusgallim), are a critical food source for migratory birds. Vegetation maps were created by classifying Landsat imagery from 2007-2011 and 2013-2017...
Pedestrian tsunami evacuation results for two tsunami-inundation zones (2009 and probable maximum tsunami (PMT)) and four travel speeds (slow walk, fast walk, slow run, and fast run) for American Samoa Pedestrian tsunami evacuation results for two tsunami-inundation zones (2009 and probable maximum tsunami (PMT)) and four travel speeds (slow walk, fast walk, slow run, and fast run) for American Samoa
This data release is comprised of a set of eight time travel map shapefiles (two tsunami inundation zones and four travel times) for use in GIS software applications and two population exposure by travel time tables (residents and nonresidences) for use in GIS software applications and other standalone spreadsheet applications. The travel time map was generated using the Pedestrian...
Simulated 1km resolution 1971-2015 ecosystem carbon variables from the IBIS model (2017/09/12) Simulated 1km resolution 1971-2015 ecosystem carbon variables from the IBIS model (2017/09/12)
This simulated ecosystem carbon dataset is derived from simulations of the parallel Integrated Biosphere simulator (pIBIS). Annual carbon variables cover 1971-2015 at 1-km (960m) spatial resolution with 3052 rows and 4823 columns. Carbon stock and flux units are in kgC/m2 and kgC/m2/yr, respectively. Data are in NetCDF format and Albers equal area projection. Overall data creation steps...
5-year Relative Fractional Vegetation Cover at Abandoned Energy Development Sites on the Colorado Plateau 5-year Relative Fractional Vegetation Cover at Abandoned Energy Development Sites on the Colorado Plateau
This data release contains a single vector shapefile and two text documents with code used to generate the data product. This vector shapefile contains the locations of 365 "plugged and abandoned" well sites from across the Colorado Plateau with their respective relative fractional vegetation cover (RFVC) values. Oil and gas pads are often developed for production, and then capped...
Grassland State and Transition Map of Canyonlands National Park Needles District and Indian Creek Grazing Allotment Grassland State and Transition Map of Canyonlands National Park Needles District and Indian Creek Grazing Allotment
This raster data depicts the modeled distribution of three grassland states: Biocrust, Grass-bare, and Annualized-bare. We developed models of bare ground, total vegetation, exotic grasses and biological soil crust using spectral data from three year composites of growing season (March-October) Landsat data in Google Earth Engine and field data that were collected over the same period at
A National Land Use And Land Cover Projection For Threat Assessment And Conservation Planning A National Land Use And Land Cover Projection For Threat Assessment And Conservation Planning
This dataset contains a projection of land use and land cover for the conterminous United States for the period 2001 - 2061. This projection used the USGS's LUCAS (Land Use and Carbon Scenario Simulator) model to project a business as usual scenario of land cover and land use change. By running the LUCAS model on the USGS's YETI high performance computer and parallelizing the computation...
