1 US Army Redstone Test Center UNCLASSIFIED Redstone Met Team

2 US Army Redstone Test Center Met Team Functions 2 Daily Forecast for RTC –Present forecast at Test Range morning briefing. – to various individuals at RTC and Redstone Arsenal. –Provide forecasts to various test facilities at RTC. Weather Advisories –Lightning within 10 & 20 miles (or other special requirements). –Severe weather (Severe Thunderstorm/ Tornado watches/warnings). –WBGT advisories. (Wet Bulb Globe Temperature is the Army standard for heat stress) –Provide forecast and real-time conditions to forestry personnel for controlled burns. –Provide Demo & Burn site real-time data and forecast conditions. Climate Data to Customers –Maintain database accessible on the internet. –Data for planning tests. Web Site –Contains: Forecast Current weather conditions on the Test Range. (15 minute updates) Daily Upper-Air Sounding (When available – normally 12Z Mon-Fri) Archived Data –Can be accessed by anyone on or off post. –Maintained locally at this time.

3 US Army Redstone Test Center Meteorological Equipment 3 Doppler Radar DWSR-88S –S Band –Enterprise Electronics Corp (Upgraded to RVP8 and RCP8 by Baron Services March 2007) –Built 1987 Installed at RTC in 1991, new dome and pedestal in 2010 –14 ft Parabolic Dish –120 NM Range –1.85° Beam width –Linear Horizontal Polarization – MHz Frequency at 550 KW Output –Outputs: Mean Velocity, Spectral Width, Calibrated Reflectivity SAMS (Surface Automated Meteorological System) –Designed by Physical Sciences Laboratory, New Mexico State University. –Installed 1986, original computer was HP1000, upgraded to PC- based in –Campbell Scientifics CR 3000 –Currently 12 DCPs (Data Collection Platforms ) in operation, can be easily expanded. –Data remotes via Radio Frequency ( MHz) to CMO/ 900MHz SpreadSpectrum – 2 meter portable DCPs can be setup at any location. –Special measurements can be configured to customer needs. –DCPs can measure the following parameters: Temperature/Humidity (2Meters AGL) Wind Direction and Speed (2Meters AGL) (Russell Tower – 106 Meters AGL) Barometric Pressure Delta T Visibility Soil Temperature (Various Depths) Solar Radiation Precipitation Additional Measurements available
