Near-real-time Herbaceous Annual Cover in the Sagebrush Ecosystem, USA, July 2018 Near-real-time Herbaceous Annual Cover in the Sagebrush Ecosystem, USA, July 2018
This dataset provides a near-real-time estimate of 2018 herbaceous annual cover with an emphasis on annual grass (Boyte and Wylie. 2016. Near-real-time cheatgrass percent cover in the Northern Great Basin, USA, 2015. Rangelands 38:278-284.) This estimate was based on remotely sensed enhanced Moderate Resolution Imaging Spectroradiometer (eMODIS) Normalized Difference Vegetation Index...
A Time Series of Herbaceous Annual Cover in the Sagebrush Ecosystem A Time Series of Herbaceous Annual Cover in the Sagebrush Ecosystem
We integrated 250-m enhanced Moderate Resolution Imaging Spectroradiometer (eMODIS) Normalized Difference Vegetation Index (NDVI) with land cover, biogeophysical (e.g., soils, topography) and climate data into regression-tree software (Cubist). We integrated this data to create a time series of spatially explicit predictions of herbaceous annual vegetation cover in sagebrush ecosystems...
Estimating carbon fluxes using satellite data integrated into regression-tree models in the conterminous United States Estimating carbon fluxes using satellite data integrated into regression-tree models in the conterminous United States
Integrating spatially explicit biogeophysical and remotely sensed data into regression-tree models enables the spatial extrapolation of training data over large geographic spaces, enhancing a more complete understanding of broad-scale ecosystem processes. This data release presents maps of estimates of annual gross primary production (GPP) and annual ecosystem respiration (RE) that were...
Near-real-time Estimates of Herbaceous Annual Cover in the Sagebrush Ecosystem (June 19, 2017) Near-real-time Estimates of Herbaceous Annual Cover in the Sagebrush Ecosystem (June 19, 2017)
This dataset provides a near-real-time estimate of 2017 herbaceous annual cover with an emphasis on annual grass (Boyte and Wylie. 2016. Near-real-time cheatrass percent cover in the Northern Great Basin, USA, 2015. Rangelands 38:278-284.)

Downscaled 30 m weekly MODIS NDVI for the Central Great Basin Downscaled 30 m weekly MODIS NDVI for the Central Great Basin
To help characterize the groundwater system at Homestake Mining Company Superfund Site near Milan, New Mexico, the U.S. Geological Survey collected borehole geophysical and groundwater-quality data in cooperation with the U.S. Environmental Protection Agency during JulyOctober 2016. The following borehole geophysical data were collected from wells at or near the Homestake Mining Company...
Landsat 8 six spectral band data and MODIS NDVI data for assessing the optimal regression tree models Landsat 8 six spectral band data and MODIS NDVI data for assessing the optimal regression tree models
In this study, we developed a method that identifies an optimal sample data usage strategy and rule numbers that minimize over- and underfitting effects in regression tree mapping models. A LANDFIRE tile (r04c03, located mainly in northeastern Nevada), which is a composite of multiple Landsat 8 scenes for a target date, was selected for the study. To minimize any cloud and bad detection...
