Dear Mr. Ward: GTE is proud to be a part of the National Weather Service (NWS), Advanced Weather Interactive Processing System (AWIPS) program. AWIPS is the cornerstone program of the NWS to improve the timeliness and accuracy of the weather forecasts and warnings that are essential to public safety. An AWIPS system is planned to be installed at your local Weather Office site and be part of a nationwide network of nearly 150 National Weather Service sites that will enable meteorologists and hydrologists around the country to prepare increasingly accurate forecasts and respond quickly to developing weather conditions. GTE provides the satellite broadcast network for the distribution of a variety of nationally and locally -needed weather information products. The NWS satellite antenna used in this network is owned by the Federal Government and installed by GTE, is a parabolic shaped, 12.5 feet (3.8 meter) in diameter, receive -only dish. It is similar in concept to a commercial TV receive -only satellite dish. No information can be transmitted from this antenna. The location selected for this antenna affords the ideal reception of the satellite data for uninterrupted NWS operations supporting your local Weather office at: National Weather Service 1200 Airport Drive (Burlington International Airport) South Burlington, VT 05403 (Primary point of contact: Luc Gosselin, Electronics Systems Analyst) (802) 658-5684 x228 ) JV'JL The antenna will be mounted on a non -penetrating load frame on the 2 d floor roof of the Burlington International Airport tenninal building as shown on the Site Map. The antenna will survive in winds up to 120 mph. The maximum height of the antenna will be 13 feet (374.59 feet above mean sea level) above the roof as depicted in Figure 3 Antenna Elevation View. Page 2 October 16, 1998 The enclosed drawings and information are for your review and approval. Your assistance in expediting the permit approval process for this application is greatly appreciated, and will benefit not only your community but also your neighboring communities through improved weather predictions that could save lives and property. Please provide feedback by December 15, 1998, that you received this letter and that your office and point of contact are still current.
