Climate and Land Use Change
This science includes the long-term alteration in the characteristic weather conditions of a region, such as changes in precipitation and temperature.
Data - Removing roads from the National Land Cover Database to create improved urban maps for the United States, 1992-2011
To better map the urban class and understand how urban lands change over time, we removed rural roads and small patches of rural development from the NLCD developed class and created four wall-to-wall maps (1992, 2001, 2006, and 2011) of urban land.
To investigate the rates, causes, and spatial and temporal patterns of forest harvest on private tracts throughout the Cascade Mountains, we relied on a new generation of annual land-use/land-cover (LULC) products created from the application of the Continuous Change Detection and Classification (CCDC) algorithm to Landsat satellite imagery collected from 1985 to 2014.
Table containing raw and normalized scores used to calculate vulnerability of 60 American Midwestern national parks to projected climate and land use changes for 2080-2099
Raw and relative (normalized) data for metrics measuring exposure (yellow columns), sensitivity (green columns), constraints on adaptive capacity (blue columns), and vulnerability for units in the US National Park Service Midwest administrative region. Stippled columns contain relative (normalized) data used to calculate the corresponding component.
USGS Southwest Repeat Photography Collection: Kanab Creek, southern Utah and northern Arizona, 1872-2010
This data release contains data, repeat images, and field notes collected from 80 repeat photography stakes along Kanab Creek 1872 and 2010. The Kanab Creek repeat photography collection is part of the USGS Southwest Repeat Photography Collection assembled over decades by USGS scientists Drs. Robert H. Webb and Raymond M. Turner and curated by the Southwest Biological Science Center.
This dataset provides information on the current status and various other habitat and descriptive attributes of the native coastal vegetation for seven of the main Hawaiian Islands (i.e., does not include Ni`ihau). Report available.
The data archive contains the aerial photographs and channel delineations used in our analysis. The images have been geo-referenced to the 1995 digital orthophoto quarter quadrangles as described by Miller and Friedman (2009). The channel delineations for all photo years (including 2003) and the delineation of the outer flood-plain boundary are stored as shapefiles.
LPJ biomes (30-year mean) simulated using monthly historical (1901-2000) CRU TS 2.1 climate data and projected future (2001-2099) CMIP3 A2 and A1B simulated climate data on a 30-second grid of the northwest United States and southwest Canada
LPJ simulated biomes for the northwest United States and southwest Canada in netCDF files.
Bioclimatic variables calculated from statistically-downscaled historical (1901-2000) CRU TS 2.1 climate data and projected future (2001-2099) CMIP3 A2 and A1B simulated climate data on a 30-second grid of the northwest United States and southwest Canada

The Borehole Temperature Logs provide temperature measurements acquired in permafrost regions of arctic Alaska between 1950 and 1988 by the USGS at 87 sites deep enough to penetrate the base of permafrost.
Meteorological data and repeat photography captured at Climate Impact Meteorological (CLIM-MET) stations located in the Canyonlands National Park and Mojave National Preserve. Data from ecologically sensitive sites in the Southwest help determine the distribution and types of surficial deposits and the processes responsible for the deposits, and contribute to understanding vegetation distribution.
A catalog of dust events in the southwestern United States since 2009. Dust emission from sources in the southwestern United States is important on local and regional scales because of its effects on air quality, human health and safety, snow melt timing and water management, and on ecosystem function through the depletion and (or) addition of soil nutrients.
