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.

"The RAWS network and RAWS data-use systems are closely reviewed and summarized in this report. RAWS is an active program created by the many land-management agencies that share a common need for accurate and timely weather data from remote locations for vital operational and program decisions specific to wildland and prescribed fires. A RAWS measures basic observable weather parameters such as temperature, relative humidity, wind speed, wind direction, and precipitation as well as "fuel stick" temperature. Data from almost 1,900 stations deployed across the conterminous United States, Alaska, and Hawaii are now routinely used to calculate and forecast daily fire danger indices, components, and adjective ratings. Fire business applications include the National Fire Danger Rating System (NFDRS), fire behavior, and fire use. Findings point to the fact that although the RAWS program works and provides needed weather data in support of fire operations, there are inefficiencies and significant problem areas that require leadership attention at the National level."
