[. . . ] www. vaisala. com Vaisala Wind Profiler LAP®-3000 Benefits Continuous wind data up to 3 km Continuous virtual temperature data up to 1. 5 km Unattended operation Minimal periodic maintenance New vertical profile every 3-60 minutes © 1999 S. [. . . ] LAP-XM® allows user defined configuration of the sampling parameters, signal processing and quality control algorithms, and multiple configurable data output formats, to provide customers location and application specific profiler operation. Up to one-year of wind and/or virtual temperature data may be stored on the radar processor. The Vaisala LAP® -3000 was jointly developed under a Cooperative Research and Development Agreement (CRADA) with the National Oceanic and Atmospheric Administration (NOAA). Over 130 LAP® -3000 systems have been deployed worldwide. Applications · Air quality · Atmospheric boundary layer research · Aviation operations · Defense · Emergency response · Global change research · Mesoscale meteorological forecasting · Offshore, shipboard observations · Vertical wind shear & turbulence · Weather modification Technical data Specification Operating frequency Minimum height 1 Maximum height 2 Range resolution (typical) Typically 915 or 1290 MHz 120 m up to 3 km 60, 100, 200, 400 m Factory configurable 45 ­ 500 m <1 m/s Wind speed accuracy 3 Wind direction accuracy <10 ° 3 - 60 minutes Wind averaging time 3 RF power output 600 W peak 0. 1 ­ 100 W average Occupied bandwidth @1290 MHz Less than 12. 5 MHz @ 400 ns pulse (99% ITU) Antenna Type Electrically steerable micropatch phased-array panels Gain ~26 dBi ~29 dBi with the extended antenna aperture RF beam width ~9 ° ~6 ° with the extended antenna aperture Aperture 2. 7 m2 @ 1290 MHz, 3. 0 m2 @ 915 MHz 6. 0 m2 @ 1290 MHz, 6. 2 m2 @ 915 MHz (extended antenna aperture) Power requirements 115 VAC/60 Hz; 15 A 230 VAC/50 Hz; 10 A Options Hardware Monitor System monitoring and status reporting Vaisala Graph-XMTM Graphical display software Moments display software Graphical moments data display software RASS 120 m Minimum height 1 up to 1. 5 km Maximum height 2 Range resolution 60, 100, 200, 400 m Factory configurable 45 ­ 500 m Temperature accuracy 1 °C Averaging time 1 - 60 minutes RASS aperture 1. 2 m2 x 4 sources Audio frequency 1. 8 - 4 kHz, Audio frequency range chosen to assure a Bragg match for the meteorological conditions and profiler operating frequency Antenna support stand For easier access to antenna components Extended antenna aperture For improved performance Extended length cables For increasing the distance from shelter to antenna GPS timing receiver For accurate timekeeping Hub computer For remote access and monitoring Services Site survey, FAT, SAT, training, installation, extended warranty, service contract. Other operating frequencies 924, 1280, 1290, 1294. xxx, 1357. 5 MHz 1 Dependent on transmit pulse duration and surrounding clutter environment. 2 Dependent on transmit pulse duration, atmospheric scattering conditions, profiler configuration, installation location, and surrounding environment. 3 Validity of data dependent on an averaging period duration sufficient to provide spacial homogeneity between sampled volumes.
