OpenNSPECT, an open-source version of the Nonpoint-Source Pollution and Erosion Comparison Tool (N-SPECT), is a plugin to the free MapWindow GIS open-source platform. Enhancements in this version of N-SPECT include faster processing time, additional coefficients for common land cover data products, and a comparison function to evaluate differences in land use scenarios.
The Impervious Surface Analysis Tool (ISAT), which is available as a geographic information system extension, is used to calculate the percentage of impervious surface area within user-selected geographic areas (e.g, watersheds, municipalities, subdivisions). In small watersheds, the correlation between an increase in impervious surfaces and a decrease in water quality has been well established. People use the information derived from ISAT to predict how different management scenarios might impact local water quality.
Climate normals are the average values of meteorological parameters -- such as temperature, precipitation, frost/freeze data, and snowfall data -- over 30-year spans. The climate normals data help describe typical climate conditions for a given place and time of year, and are used as a baseline to which current conditions can be compared.
The National Solar Radiation Database contains 30 years (1961-1990) of solar radiation and supplementary meteorological data, and hourly solar radiation and meteorological data for 237 National Weather Service sites in the United States, Guam, and Puerto Rico. Also includes maps of the monthly amounts of solar power that could be generated with various solar collectors.
Seven stations continuously collecting solar, infrared, meteorology, and ultraviolet radiation data are located in climatologically diverse regions of the U.S.—including Colorado, Illinois, Mississippi, Montana, Nevada, Pennsylvania, and South Dakota.
Carbon Dioxide Information Analysis Center (CDIAC)
December 28, 2012
The CDIAC is the primary global-change data and information analysis center of the U.S. Department of Energy (DOE). It contains information on concentrations of carbon dioxide and other radioactively active gases in the atmosphere; the role of the terrestrial biosphere and the oceans in the biogeochemical cycles of greenhouse gases; emissions of carbon dioxide to the atmosphere; long-term climate trends; the effects of elevated carbon dioxide on vegetation; and the vulnerability of coastal areas to rising sea level.
Voluntary Reporting of Greenhouse Gases-Carbon Management Evaluation Tool
December 28, 2012
A decision support tool for agricultural producers, land managers, soil scientists and other agricultural interests, COMET-VR estimates soil carbon changes for management alternatives for a ten-year projection period within each Major Land Resource Area (MLRA) allowing users to estimate soil carbon sequestration on a parcel of land. The COMET-VR tool is provided by the U.S. Department of Agriculture.
Twice per day NOAA's National Weather Services publishes digital maps that show national forecasts for ozone, smoke, and dust. Ozone is shown as 1-hour and 8-hour concentrations. Official Air Quality point forecasts, issued by state and local air quality forecasters, along with additional information on air quality can be found under EPA's AIRNow site. Surface and column-averaged concentrations of predicted smoke for large fires are displayed as 1-hour averages, updated each day.
