In the Nano-resolution mode, the MET4 and MET4A have a pressure resolution of parts-part-per billion (nano-bars). Overall accuracy is better than \u00b10.08 hPa even under harsh environmental conditions. The high pressure resolution and accuracy permit measurements of infrasound signals over an extended frequency spectrum including signals from microbaroms, tornadoes, severe weather, tsunamis, volcanic eruptions, avalanches, explosions, and sonic booms. Excellent stability permits long-term measurements used for weather and climate studies as well as GPS-MET sensing of precipitable water used in flash flood warning networks.<\/p>\n<p>These fully-integrated systems are housed in environmental enclosures allowing indoor or outdoor mounting. The MET4 solar radiation shield protects the temperature and humidity sensors from precipitation and solar radiation. Both the MET4 and fan-aspirated MET4A utilize a high performance pressure port to reduce the dynamic pressure errors caused by wind.<br \/>\nTemperature resolution is better than 0.01 degrees C. Installation hardware and software are included and optional interface cabling is available.<\/p>\n<p>Microprocessor-based electronics provide fully temperature compensated and linearized outputs via a bi-directional RS-232\/485 interface. This serial interface allows complete remote configuration and control of all operating parameters including resolution, sample rates, choice of engineering units, integration time, and sampling commands. The airport barometric functions include field pressure, station pressure, altimeter setting, sea-level pressure, density altitude, pressure altitude, Q Codes - QNH &amp; QFE and WMO pressure tendency codes. The internal data logger can store over 200,000 high resolution data points.<\/p>\n<p>Documentation available for download from the Download area.<\/p>","protected":false},"excerpt":{"rendered":"<p>MET4 \u2013 MET4A Broadband Meteorological Measurement Systems<\/p>\n<p>The MET4 and fan-aspirated MET4A Meteorological Measurement Systems provide high accuracy data from barometric\npressure, temperature, and relative humidity sensors.
