Data Release for The sensitivity of ecosystem service models to choices of input data and spatial resolution

Although ecosystem service (ES) modeling has progressed rapidly in the last 10-15 years, comparative studies on data and model selection effects have become more common only recently. Such studies have drawn mixed conclusions about whether different data and model choices yield divergent results. In this study we apply inter- and intra-model comparisons to address these questions at national and p

Landsat Burned Area Essential Climate Variable products for the conterminous United States (1984 -2015)

The U.S. Geological Survey (USGS) has developed and implemented an automated algorithm that identifies burned areas in temporally-dense time series of Landsat image stacks to produce the Landsat Burned Area Essential Climate Variable (BAECV) products. The algorithm makes use of predictors derived from individual Landsat scenes, lagged reference conditions, and change metrics between the scene and

Data Release of OSL, 14C, and U-series age data supporting geologic mapping along the South Platte River corridor in northeastern Colorado

In conjunction with geologic mapping of four 7.5′ quadrangles along the South Platte River corridor in northeastern Colorado (Masters, Orchard, Weldona, and Fort Morgan), geochronology samples were collected and analyzed using optically stimulated luminescence (OSL), radiocarbon (14C), or U-series methods to provide age control for mapping units. This section of river corridor is largely covered b

Data release of Geologic Map of the Upper Arkansas River Valley Region, North-Central, Colorado

This 1:50,000-scale geologic map represents a compilation of the most recent geologic studies of the upper Arkansas River valley, between Leadville and Salida, Colorado. The valley is structurally controlled by an extensional fault system that forms part of the prominent northern Rio Grande rift, an intra-continental region of crustal extension. This work also incorporates new detailed geologic ma

Colorado Landcarbon: Accounting for Wildfire

Disturbance disrupts the balance between gross primary productivity and respiration, resulting in a net C loss for some time after a stand-replacing fire. However, our understanding of this process is based on a limited number of studies. Ecosystem C recovery post-fire must be explicitly and carefully examined in order to generate accurate predictions of C cycle impacts of future wildfires and cha

Geologic map of the Strawberry Butte 7.5' quadrangle, Meagher County, Montana

The Strawberry Butte quadrangle, scale 1:24,000, is a legacy map of the U.S. Geological Survey, made as part of the Montana Investigations Project to provide information on the stratigraphy, structure, and geologic history of the area. The quadrangle encompasses an area of about 132 km2 (51 mi2) in the southwest part of the Little Belt Mountains and is about 26 km (17 mi) north of White Sulphur Sp

Data Release for the influence of data characteristics on detecting wetland/stream surface-water connections in the Delmarva Peninsula, Maryland and Delaware

The datasets were generated for the Upper Choptank River Watershed in Maryland and Delaware. Depressions and the total stream network were derived from a lidar DEM collected during AprilJune 2003 (vertical accuracy root mean square error (RMSE) = 14.3 cm) and MarchApril 2006 (vertical accuracy RMSE = 18.5 cm) for Maryland (1 m resolution) and April 2007 (vertical accuracy RMSE = 18.5 cm) for Delaw

Argon data for Poncha Pass Geologic Map

This dataset was collected by Leah E. Morgan and Michael A. Cosca in the Argon Geochronology Laboratory of the USGS in Denver, Colorado in 2015. The dataset contains full raw argon isotopic data for samples presented in: Geologic Map of the Poncha Map Area, Chaffee, Fremont, and Saguache Counties, Colorado.

OSL methods and field and laboratory data for Mesa Verde soils to support journal article

Thin loess deposits on the uplands of the southeastern Colorado Plateau have previously not been well studied. We sampled deposits and soils from trenches on Hatch Point mesa near Canyonlands National Park, Utah, and from two outcrops in Mesa Verde National Park, Colorado. At Hatch Point, the oldest buried unit yielded two OSL ages of 10,370 and 7,555 yr; the middle unit yielded 10 OSL ages from 6

Data Release of the bedrock geology and hydrostratigraphy of the Edwards and Trinity aquifers within the Driftwood and Wimberley 7.5-minute quadrangles, Hays and Comal Counties, Texas

The Edwards and Trinity aquifers are major sources of water in south-central Texas and are both classified as major aquifers by the State of Texas. The population in Hays and Comal Counties is rapidly growing, increasing demands on the area's water resources. To help effectively manage the water resources in the area, refined maps and descriptions of the geologic structures and hydrostratigraphic

Climate Impact Meteorological Stations (CLIM-MET) Data from The Mojave National Preserve, California and Canyonlands National Park, Utah 1998-2016.

The CLIM-MET stations are meteorological/geological stations that are designed to function in remote areas for long periods of time without human intervention. These stations measure meteorological and wind-erosion parameters under varying climatic and land-use conditions to detect and describe ongoing landscape changes. Combined with historic and other data, CLIM-MET data can provide inputs into

Review of articles pertaining to landscape perceptions

This data file contains a list of journal articles found in a recent search for research relevant to studying landscape perceptions. We collected all peer reviewed academic articles containing the keywords landscape and perception on the web of science resulting in 3497 records. To eliminate studies not directly addressing landscape perception we filtered out medical journal articles (n=1211). We
