Remote Automatic Weather Station for Resource and Fire Management Agencies (Classic Reprint) by John R Warren Pdf
Excerpt from Remote Automatic Weather Station for Resource and Fire Management Agencies Meteor-burst communications systems utilize the ionized trails of meteors to effectively bounce radio frequency transmissions over great distances (up to 500 miles [804 km] or so). The usable time of an ionized trail is short, but it is often sufficient to establish a two-way path with a duration adequate for data bursts that could contain weather data. Experimentation has arrived at the statistical probabilities of success, number of inter rogations, etc., for various parts of the western United States and Alaska at different times of the year. A meteor burst system is in use for snow measurements. At the time of selection of the raws-goes, the meteor-burst system was not operational; planned snow measurement sites were not compatible with fire weather sites; the remote stations were larger (some requiring commercial power); and there were no cost or performance advantages. Opera tion was also limited to the western United States and Alaska. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
