NOAA's National Climatic Data Center (NCDC) has developed a number of products and services over the past several years to provide data and information related to US and global climate and weather extremes. These products and services are intended to serve a variety of constituents: government, educational, research, private sector, news media, individual, etc. By working with various user groups to determine requirements, NCDC has made use of existing data in its digital archives to convert large holdings of data into more useful information. Examples include a service to provide long-term extremes of various parameters by location, county, or state; GIS Services to easily locate stations with available data; climate monitoring products to track extremes such as for snowfall; a monitoring system to display trends in 12 indicators of climate extremes across North America; monthly global hazards summaries with narrative and impact information; and numerous other products. In each case, the intent of the product or service is to address requirements both within and outside of NOAA, and to better inform the public about climate and weather extremes.
