Map Information

This nowCOAST™ geolinks map service provides maps depicting the locations of surface and upper-air in-situ observing stations along with hyperlinks to the web sites posting the latest data from these observing stations. The web sites are operated by NOAA, EPA, USGS or local or state governmental agencies. The surface observations include 1) weather observations, 2) ocean/estuary/lake observations, 3) river observations, 4) water quality observations, and 5) air quality observations. These five types of observations are described briefly below.

The hyperlinks to the web pages posting the observations can be accessed by performing an identify or query operation on the desired map layer, which will return the attributes of any matching feature(s). The hyperlink is stored in the "URL" attribute field.

Weather Observations:

The weather observations layer includes links to NOAA web pages posting the latest meteorological data from terrestrial and maritime surface observing sites. The terrestrial stations consist of the following networks: ASOS, AWOS, Remote Automated Weather Station (RAWS) network, non-automated weather stations, U.S. Climate Reference Network (CRN), several state DOT Road Weather Information Systems and U.S. Historical Climatology Network Modernization. The maritime sites include stations and platforms of the following networks: NOS/CO-OPS' National Water Level Observation Network (NWLON) and Physical Oceanographic Real-Time System (PORTS), NWS/NDBC's Coastal-Marine Automated Network (C-MAN) and Fixed Buoy network, and Regional Ocean Observing Associations' fixed buoys and stations.

Ocean/Estuary/Lake Observations:

The ocean/estuary/lake observations layer includes links to mainly NOAA and USGS web pages posting the latest physical oceanographic or limnological data (e.g. water temperature, salinity, wave heights, water level, water currents) from nation-wide observing networks including: NOS/CO-OPS NWLON and NOS/CO-OPS PORTS networks, USGS National Streamflow Information Program networks, NWS/NDBC and partners' fixed buoys, NWS/NDBC and partners' coastal stations, Canadian water level observing network, National Estuarine Research Reserve System network, and Environment Canada fixed buoys. It also includes regional, state, and local observing networks. Examples include the Great Bay (NH) Environmental Monitoring Network and offshore fixed drilling platforms in the Gulf of Mexico.

River Observations:

The river observations layer includes links to NWS and USGS web pages posting the latest river observations (e.g. stage or gage height, pool elevation, discharge, water temperature, specific conductivity) from the USGS National Streamflow Information Program networks and NWS-coordinated Automated Flood Warning Systems (AFWS), also referred to as the Integrated Flood Observing and Warning System (IFLOWS).

Water Quality Observations:

The water quality observations layer includes links to mainly USGS and NOAA web pages posting the latest water quality observations (e.g. pH, turbidity, dissolved oxygen, nitrate) from the USGS National Streamflow Information Program networks, National Estuarine Research Reserve System network, and some state environmental agencies (e.g. Maryland Dept. of Natural Resources).

Air Quality Observations:

The air quality observations layer includes links to U.S. EPA web pages posting the latest air quality observations (e.g. Air Quality Index, Ozone, Particulates) from from local, state, tribal, and federal observing sites via the centralized U.S. EPA AirNow web site.

Upper-Air Observations:

The upper air, in-situ observations layer includes links to NWS web pages posting the latest atmospheric sounding data from radiosondes released at upper-air observing stations around the U.S. The data are usually valid at 00 or 12 UTC. The web pages display the observed data using different types of plots (e.g. Skew-T, Hodograph) along with a variety of severe weather indices (e.g. CAPE, Supercell Composite Parameter). These pages were developed by NWS/NCEP/SPC to help weather forecasters with real-time sounding analysis and diagnosis. Help in interpreting the data, indices, and plots can be found at the two SPC web pages listed in the References section.

Background Information

The location information is obtaining by harvesting station inventories from different agencies such as NWS, NOS, USGS, EPA, etc. The inventories are updated at least once per year. Thus, the accuracy of the station location and what variables are recorded and posted on a provider's or data disseminator's web page depends on the accuracy of the inventories.

Time Information

This map service is not time-enabled.
