This survey was used in a study on the use of scientific information in public natural resource management planning and decision-making. This survey was intended to help staff at the Southwest Climate Science Center (SWCSC), and others in the research community, gain a more specific understanding of the kinds of decisions made by public natural resource officials and to identify how scientific information, and in particular climate information, is obtained and applied in National Environmental Policy Act (NEPA) natural resource decision-making processes. Aside from questions and associated information, the survey document contains page logic describing actions taken in a web-based environment.
The evaluation of historical water use in the Upper Rio Grande Basin (URGB), United States and Mexico, using Landsat-derived actual evapotranspiration (ETa) from 1986 to 2015 is presented here as the first study of its kind to apply satellite observations to quantify long-term, basin-wide crop consumptive use in a large basin. The rich archive of Landsat imagery combined with the Operational Simplified Surface Energy Balance (SSEBop) model was used to estimate and map ETa across the basin and over irrigated fields for historical characterization of water-use dynamics. Monthly ETa estimates were evaluated using six eddy-covariance (EC) flux towers showing strong correspondence (r2 > 0.80) with reasonable error rates...
Agenda for the Green River Basin - Landscape Conservation Design, Oversight Team meeting in Salt Lake City, Utah on April 22,2015.
When the Earth experiences changes in its climate, wildlife respond by moving – species adjust their ranges to track changes in climate, moving out of areas that become too hot or otherwise inhospitable, and moving into areas that become newly hospitable. However, climate change is now proceeding so quickly that it is becoming difficult for species to move fast enough to keep pace. In addition, today’s landscapes feature significant barriers to movement presented by human land uses (e.g., roads, cities, farms). Such is the case in the region around the border of Washington and British Columbia, where increasing development pressure and limited coordination of land and wildlife management across the border pose a...
The Operational Simplified Surface Energy Balance (SSEBop) model uses the principle of satellite psychrometry to produce spatially explicit actual evapotranspiration (ETa) with remotely sensed and weather data. The temperature difference (dT) in the model is a predefined parameter quantifying the difference between surface temperature at bare soil and air temperature at canopy level. Because dT is derived from the average-sky net radiation based primarily on climate data, validation of the dT estimation is critical for assuring a high-quality ETa product. We used the Moderate Resolution Imaging Spectroradiometer (MODIS) data to evaluate the SSEBop dT estimation for the conterminous United States. MODIS data (2008–2017)...
