This National Oceanic and Atmospheric Administration (NOAA) map service displays data compiled from extreme statistics for U.S. stations using monthly summaries for three weather elements: temperature, precipitation, and snowfall. Integrated Surface Data (ISD) is digital data set DSI-3505, archived at the National Climatic Data Center (NCDC). The ISD database is composed of worldwide surface weather observations from over 20,000 stations. It has been collected and stored from sources such as the Automated Weather Network (AWN), the Global Telecommunications System (GTS), the Automated Surface Observing System (ASOS), and data keyed from paper forms.ISD refers to the digital database and format in which hourly and synoptic (3-hourly) weather observations are stored. The format conforms to Federal Information Processing Standards (FIPS). The database includes data originating from various codes such as synoptic, airways, METAR (Meteorological Routine Weather Report), and SMARS (Supplementary Marine Reporting Station), as well as observations from automatic weather stations. The data are sorted by station-year-month-day-hour-minute. Parameters included are: air quality, atmospheric pressure, atmospheric temperature/dew point, atmospheric winds, clouds, precipitation, ocean waves, tides and more.Data currency: Current NOAA map service.For additional information, please contact the National Climatic Data Center (NCDC) at ncdc.orders@noaa.gov.___________________________Other Health Datapalooza focused content that may interest you: Health Datapalooza Health Datapalooza
