: Larry, I have looked at these links and have spent the last few hours wandering about the web. What I cannot find out is whether I can receive these photos south of the equator. Seems like a great system at a reasonable cost. Can you advise please. cheers Peter N.Z. yacht Herodotus Peter, the Satellite Services Division of NOAA, our weather bureaucrats, is on : http://www.ssd.noaa.gov/ with full access to all weather products that come down from the birds. The birds do an extensive tropical zone picture set every few hours that come down on 137 Mhz. They also take a "full disk" picture of the whole hemisphere you may find useful. However, their sector scans appear to be limited to the northern edge of South America up to Canada...the Caribbean and USA. If there is some particular weather of interest to the US Military or commercial interests, they make special arrangements to photograph it in IR/Visible/Water Vapor if it's over the bird's horizon, including South America. Of course, Geostationary Equatorial satellites, even so high up, cannot see the very high latitudes in either direction. The website also contains MITSAT pictures from the Antarctic, south of NZ to Siberia. These satellites are over your horizon for direct contact, making it impossible. Full disk images from Meteosat: http://www.goes.noaa.gov/FULLDISK/GMIR.JPG are also from this website, which covers the whole South Atlantic in its full disk pictures. I'm not sure what frequency Meteosat operates on for direct download of its pictures. Search Google for Meteosat schedules and you should be able to find them with the transmission times. South America is on the western edge of Meteosat's view from over Africa. This bird's pictures are fantastic as they show the spawning grounds of the hurricanes headed for me. A massive gallery of GOES pictures from the two 137 Mhz birds is stored, forever I think, on: http://cimss.ssec.wisc.edu/goes/misc...ng_images.html which will show you what kind of pictures it takes, including the Southern region. Here's a tropical cyclone off the Brazilian Coast: http://cimss.ssec.wisc.edu/goes/misc/040326/040326.html Those pictures would be available on the 137 Mhz receiver from Hamtronics. However, I do not see a "regular schedule" of South Atlantic pictures, probably as it would require too much precious fuel to spin the bird around all the while to take them. Larry -- |
