![]() ![]() ![]() Careful analysis of Storm Relative Motion (SRM) and Base Reflectivity products within the lower elevation slices for distinct indicators of tornadic activity isĮssential to setting the appropriate warnings for areas at, and south of, Will not vary significantly enough to detect tornadic activity that has This altitude may lower slightly during super-refractive and trapping conditions but Under standard atmospheric conditions, the lowest altitude that phenomena may be detected over NAS Pensacola is approximately 4,900 feet. NAS Pensacola is located 52 nm east-southeast (113ĭeg) from the Mobile NEXRAD radar site. Radar, make it difficult for the radar site to detect tornadic activity Radar horizon problems combined with complicated calculations used by the NEXRAD Watchstanders have the ability to access selected other NEXRAD radar sites by using dial-up capabilities. Weather data is received from a dedicated line connected to the actual radar site in Mobile, Alabama. NAVTRAMETOCFAC operates and maintains a WSR-88D Next Generation Radar (NEXRAD) Principal User Processor (PUP) terminal that is part of the national, multi-departmental NEXRAD system. A standard 4 inch plastic rain gauge is located on the roof of Building 1852.Ħ. The hand-held anemometer (PMQ-3) is maintained in its case and stored in theĥ. ThereĪre four additional indicators located in the tower and seven additionalĮ. System, is located on the east bulkhead in the observer spaces. The Digital Remote Wind Speed Indicator (ID-2447/U), a component of the DASI Four wind indicators, calibrated to Magnetic North, are mounted in the controlĭ. Is mounted in the forecast spaces on the north bulkhead.Ĭ. An ID-586/UMQ-5 wind speed and direction display, calibrated to True North, The AN/UMQ-5 Aerovane is located on the roof of the tower at the southwestī. DASI indicators are located in the Facility, the control tower, and in the Radar Air Traffic Control Center (RATCC).Ī. This system, known as the DASI, is located at the observer desk and is utilized to transmit and display a digital altimeter setting to remote indicators. Digital Altimeter Sensor/Translator (ML-6661/F). A Belfort Marine Microbarograph is located in observer spaces.ī. WGBT is passed to NASC for determination of physical training flag conditionsĪ. ![]() The Questemp Area Heat Stress Monitor, which is on loan from NASP Branch MedicalĬlinic but maintained in the observer spaces, is used to compute wet-bulb global temperature (WBGT). Electric (ML-450A/UM) and sling psychrometers are maintained in the observer spaces.ī. Other observing equipment serves as backup to the ASOS.Ī. ASOS became the primary sensor group for NAVTRAMETOCFAC on 26 April 1995. Observers can also manually enter data into this system. Sensor groups are located 1235’ north of the centerline of Runway 07L-25R. In addition to the monitor at the Facility, a second ASOS monitor is located in the control tower. ASOS is capable of monitoring sky condition, visibility, present weather and intensity, obstructions to visibility, pressure, temperature, dewpoint, wind speedĪnd direction, and precipitation amount. It is designated to automatically collect, process, and archive weather sensor ASOS is the primary weather recording system at KNPA. Automated Surface Observation System (ASOS). ![]()
