An online data viewer from NOAA's Coastal Services Center providing user-friendly access to regional land cover and land cover change information. The Land Cover Atlas eliminates the need for desktop geographic information system software, or advanced technical expertise, by processing Coastal Change Analysis Program data for the user and providing easy access. The tool summarizes general change trends (such as forest losses or new development) and can highlight specific changes of interest (salt marsh losses to open water, or evergreen forest losses to development, for instance).
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.
This free PC-based tool from NOAA's Coastal Service Center aids in decisions about conservation, restoration, and planning. The Habitat Priority Planner takes away much of the subjective nature of the process by providing critical habitat analyses that are consistent, repeatable, and transparent. The program allows users to easily test various ideas and "what if" scenarios on the fly, making it the perfect tool to use in a group setting.
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.
