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.

Impervious Surface Analysis Tool

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.


CanVis is a visualization program used to see potential impacts from coastal development or sea level rise. Users can download background pictures and insert the objects (hotel, house, marina, or other objects) of their choosing. The free PC-based software is used by municipalities to brainstorm new ideas and policies, undertake project planning, and make presentations.

Climate Normals

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.

Blended Seawinds

This data product provides high-resolution six-hourly, daily, and monthly wind speeds over the world’s oceans at 10-meter height.  Data are available from 1987 to the present. 

Residential Energy Demand Temperature Index (REDTI)

This index is based on population-weighted heating- and cooling-degree days. The REDTI tool is valuable for explaining year-to-year fluctuations in energy demand for residential heating and cooling.

Sustainable Energy and Atmospheric Sciences Seminars

A monthly seminar series designed to enhance communication and collaboration among scientists at the National Renewable Energy Laboratory, NOAA's Earth System Research Laboratory, and others in the community working on issues related to renewable energy. This seminar series brings together those who can combine their knowledge and expertise to solve the problems that have slowed the integration of renewable energy sources into the U.S. electric grid.

Local Government Climate and Energy Strategy Series

The Local Government Climate and Energy Strategy Series, published by the U.S. Environmental Protection Agency, gives a straightforward overview of greenhouse gas (GHG) emissions reduction strategies that local governments can use to achieve economic, environmental, social, and human health benefits. The series covers energy efficiency, transportation, community planning and design, solid waste and materials management, and renewable energy.

This short, animated video describes what is meant by climate, its characteristics, and the range of impacts due to climate change. The difference between mitigation and adaptation is also discussed.

Global Sea Level Rise Scenarios for the United States National Climate Assessment

Global sea level has been steadily rising for decades and is expected to continue. Scientists have very high confidence that global sea level will rise at least another 8 inches and as much as 6.6 feet by 2100, causing significant impacts in U.S. coastal regions.  This report lays out the science and describes possible scenarios to help planners and policy leaders assess the risks.
