Doppler Radar KML. While the RIDGE radar display allows for the use of interactive toggles with the image, RIDGE images can be best utilized with GIS software. This page allows you to create "kmz" files which are compressed "kml" files compatible with several GIS software applications. A list of some of the software applications that support KML can be found here. Visit the NWS website Standards Description Website which explains KML in more detail.

With the kmz files below, you can display any of the the National Weather Service RIDGE radar images including polygons. Choose your overlay from any of the following possibilities... a single NWS radar image by individual radar by a statewide composite multiple images by individual radar, orchoose any combination of radars and images.Real-time NWS polygon warnings KML 2.1 and some earth viewing applications support animation of image overlays.

The National Weather Service Mission The National Weather Service provides weather, hydrologic, and climate forecasts and warnings for the United States, its territories, adjacent waters and ocean areas, for the protection of life and property and the enhancement of the national economy. NWS data and products form a national information database and infrastructure which can be used by other governmental agencies, the private sector, the public, and the global community. It is accomplished by providing warnings and forecasts of hazardous weather, including thunderstorms, flooding, hurricanes, tornadoes, winter weather, tsunamis, and climate events.

The NWS is the sole United States OFFICIAL voice for issuing warnings during life-threatening weather situations. NWS Gages Download. AHPS Downloads While the AHPS display allows for the use of interactive toggles with the image, AHPS data can also be utilized within GIS software.

Precip Frequency Data Server. The Precipitation Frequency Data Server (PFDS) is a point-and-click interface developed to deliver NOAA Atlas 14 precipitation frequency estimates and associated information.

Precip Frequency Data Server

Upon clicking a state on the map above or selecting a state name from the drop-down menu, an interactive map of that state will be displayed. From there, a user can identify a location for which precipitation frequency estimates are needed. Estimates and their confidence intervals can be displayed directly as tables or graphs via separate tabs. Links to supplementary information (such as ASCII grids of estimates, associated temporal distributions of heavy rainfall, time series data at observation sites, cartographic maps, etc.) can also be found. NOAA Atlas 14 documents provide additional information on the underlying data and functioning of the PFDS. NWS Cooperative Observer Program.
