This geospatial rendering of weather radar sites gives access to an historical archive of Terminal Doppler Weather Radar data and is used primarily for research purposes. The archived data includes base data and derived products of the National Weather Service (NWS) Weather Surveillance Radar 88 Doppler (WSR-88D) next generation (NEXRAD) weather radar. Weather radar detects the three meteorological base data quantities: reflectivity, mean radial velocity, and spectrum width. From these quantities, computer processing generates numerous meteorological analysis products for forecasts, archiving and dissemination. There are 159 operational NEXRAD radar systems deployed throughout the United States and at selected overseas locations. At the Radar Operations Center (ROC) in Norman OK, personnel from the NWS, Air Force, Navy, and FAA use this distributed weather radar system to collect the data needed to warn of impending severe weather and possible flash floods; support air traffic safety and assist in the management of air traffic flow control; facilitate resource protection at military bases; and optimize the management of water, agriculture, forest, and snow removal. This data set is jointly owned by the National Oceanic and Atmospheric Administration, Federal Aviation Administration, and Department of Defense.

The National Weather Service (NWS) maintains historical Atlantic Ocean hurricane weather data in a format that can be exploited by Graphic Information System (GIS) software. Using KML/KMZ formats, it takes the numbers and words from the rows and columns in databases and spreadsheets and puts them on a map. This data file contains information about named and unnamed Altantic tropical storms and hurricanes from 1851 to 2006. Once downloaded, the file can be decompiled by decade and by year in a a KML/KMZ GIS viewer.

The National Weather Service (NWS) National Operational Hydrologic Remote Sensing Center (NOHRSC) provides comprehensive snow observations, analyses, data sets and map products. Available to all, these products specifically support a wide variety of government and private-sector applications in water resource management, disaster and emergency preparedness, weather and flood forecasting, agriculture, transportation, and commerce.

The National Weather Service (NWS) Storm Prediction Center (SPC) routinely collects reports of severe weather and compiles them with public access from the database called SeverePlot (Hart and Janish 1999) with a Graphic Information System (GIS). The composite SVRGIS information is made available to the public primarily in .zip files of approximately 50MB size. The files located at the access point have organized severe weather data by County Warning Area (CWA). A CWA is a grouping of counties for which severe weather information is distributed. Although available to all, the data provided may be of particular value to weather professionals and students of meteorological sciences. An instructional manual is provided on how to build and develop a basic severe weather report GIS database in ArcGis and is located at the technical documentation site contained in this metadata catalog.

The composite SVRGIS information is made available to the public primarily in .zip files of approximately 50MB size. The files located at the access point contain composite track information regarding tornados, large hail, and damaging winds for the period 1950-2006. Although available to all, the data provided may be of particular value to weather professionals and students of meteorological sciences. An instructional manual is provided on how to build and develop a basic severe weather report GIS database in ArcGis and is located at the technical documentation site contained in this metadata catalog.

This study was based on the sediment quality triad (SQT) approach. The purpose was to define the extent and magnitude of contamination and biological effects associated with contaminants in the Massachusetts/Cape Cod Bays, Stellwagen Bank, and Boston Harbor. A stratified probabilistic sampling design was utilized to characterize the systems in terms of chemical contamination and benthic infaunal community structure. In addition, samples were taken in the vicinity of the new Boston sewage outfall in Massachusetts Bay and in Boston Harbor where the sewage outfall used to discharge. Toxicity bioassays were not done. A secondary objective was to coordinate with the NOAA NMFS to collect sediment and fish tissue samples at previously sampled Benthic Surveillance Program sites. This file contains sediment and water data measured in all areas sampled in 2004.

The composite SVRGIS information is made available to the public primarily in .zip files of approximately 50MB size. The files located at the access point contain track information regarding known tornados during the period 1950 to 2006.

The National Weather Service (NWS) maintains historical Eastern Pacific Ocean hurricane weather data in a format that can be exploited by Graphic Information System (GIS) software. Using KML/KMZ formats, it takes the numbers and words from the rows and columns in databases and spreadsheets and puts them on a map. This data file contains information about named and unnamed Eastern Pacific Ocean tropical storms and hurricanes from 1949 to 2006. Once downloaded, the file can be decompiled by decade and by year in a a KML/KMZ GIS viewer.
