History Satellite Services DirecTV and Dish Network Services Thank you for watching PBS. We are pleased to note that the majority of satellite customers are now able to receive local channels. As satellite providers continue to expand the locations where they offer local channels, more and more viewers will be able to receive their local PBS station(s) instead of the PBS national feed. To find out more information about PBS service through your satellite provider, please click one of the choices below: DirecTV or Pegasus DISH Network Change to the National PBS Feed Starting November 16, 2007 As you are aware, PBS has provided a one-day delayed primetime schedule that distinguished the satellite service from local PBS stations' primetime listings. Due to satellite capacity constraints as PBS expands digital programming, PBS has made the decision to consolidate some of its satellite feeds. This process means that the PBS service available on DIRECTV and DISH Network will no longer delay the primetime schedule, but will align all programming for DBS customers alongside those on PBS member stations throughout the country. This change is to take place on Friday, November 16, 2007 with the evenings's primetime schedule.

CIMSS Satellite Blog A weblog of meteorological satellite imagery relevant to current weather events Cold night-time temperatures in the Upper Midwest January 24th, 2008 AWIPS images of the 4-km resolution GOES-12 10.7µm IR channel (above) showed that the land surfaces across the Upper Midwest region exhibited very cold brightness temperature values (darker blue enhancement) during the pre-dawn hours on 24 January 2008 -36ºC in northern Wisconsin, and -38ºC in northern Minnesota. Most of the area seen in the images above was cloud-free (except for the lake-effect cloud bands downwind of Lake Superior and Lake Michigan); the cloud-free surfaces could then be seen warming very quickly after sunrise. Much of the northcentral US had a deep snow cover of at least 5-10 inches, with snow depths of 15-30 inches common in northern Minnesota, Wisconsin, and Michigan; this deep snow cover (along with cloud-free skies and light winds) allowed for very strong radiational cooling of the air near the surface.

83. The Image Satellite Weather People Need. When you see a forecast video image satellite weather photos and animations offer us larger pictures. http://www.stuffintheair.com/image-satellite-weather.html

An image satellite weather folks check. How do we interpret satellite imagery? To use the pictures from the image satellite weather specialists need to process and customize the information. See the sample photos in this book, for instance. Now Available: Only $45.14 Seriously want to be a weather forecaster? Essential training manual in Satellite Meteorology. The image satellite weather technology has been around a while, but it has become vital to the great advances in weather forecasts we have seen over the last 50 years or so. For example, see a sample satellite image for Calgary, Alberta Canada. We can derive planet temperatures, humidity pictures, cloud pics and wind data from the satellite depictions. Both for identifying long-term trends and providing the greater precision needed for short-term weather predictions, sometimes called nowcasting . Satellite pix offer us enhanced perspective for use in air pollution studies as well. Large scale image satellite weather photography has become important to pilots flying into areas with a sparse surface weather data. We can extract the information they need from a series of photographs. Weather satellite history The first weather satellite: Tiros-1 (1 tiros) in 1960, USA.
