Satellite Imagery

Unidata has a special set of data products prepared at the Space Science and Engineering Center (SSEC) at the University of Wisconsin, Madison. One special feature of this data stream is satellite imagery. For the most part, the images are from Geostationary Orbiting Environmental Satellites (GOES), but certain data from other satellite observing platforms can be injected on special request. Currently SSEC is the IDD injection point for all satellite imagery.

High Interest Images

Hurricane Andrew
 After Hitting Florida Hurricanes generate some of the highest interest in weather data on the Internet. The University of Michigan used its Unidata systems to capture this images of Hurricane Andrew and make it available on their WWW server.

Composite Weather Maps

 with Station Reports and Satellite Image In this map generated at Purdue , an infrared satellite image provides the background for the conventional data from the Domesitic Data Service. The satellite image is delivered via the IDD from the University of Wisconsin Space Science and Engineering Center (SSEC). To generate the map, the Unidata Local Data Manager (LDM) software (which is the heart of the IDD at each site) is constantly capturing data both from the Domestic Data Service stream and satellite imagery stream from SSEC. The LDM can be configured to spawn an applications program upon the receipt of certain data products. The application program, Purdue's WXP in this case, is used to generate the composite map.

Global Information

 Montage of Satellite and Surface Data Data from a number of different observing platforms can be combined to provide a global coverage of the planet. The SSEC Global Montage displays these data in a striking image. Data from several satellites show the cloud cover and sea surface temperatures, while conventional surface observations (referred to as "Synoptic Obs" in the legend) are shown as color contours on the land masses. This dramatic display of the state of the globe is generated every six hours at the University of Wisconsin. Note that not all the satellite data in this image is currently being distributed via the IDD, but the IDD is capable of carrying it. The data from the international ground observing stations are delivered from the International Data Service (IDS) which is available on a regular basis via the IDD.
