The Laser Induced Fluorescence (LIF) system developed by CETEMPS measures the concentrations of nitrogen dioxide (NO₂), directly and the concentrations of peroxy nitrates (RO2NO₂), alkyl nitrates (RONO₂) and nitric acid (HNO₃), after thermal dissociation into NO₂. The LIF uses a Yag laser at emits at 532 nm with a frequency of 10 kHz. The detection limit of the LIF is 3.6 pptv. The high frequency (10 Hz) of the system allows to calculated the flux of the species above using the Eddy Covariance technique. The LIF was used during summer 2007 intercomparison campaign in L’Aquila with an instrument of the Tokyo Metropolitan University and in the summer 2008 in the OP3 campaign in the Borneo forest in Malaysia. The instrument is recently certificated by the British Aerospace and installed onboard the FAAM BAe-146 aircraft. The LIF will be used during July 2010 and Jannuary 2011 in the RONOCO campaign in UK and in summer 2011 in Canada during the BORTAS campaign. Go to LIF website (under construction)...

Meteorological Radio Detection And Ranging (RADAR) it is an instrument that through the emission of short impulses of electromagnetic signals of elevated power measures the quantity of hydrometeors (rain, snow, ice) suspended in the atmosphere. The main advantage is the possibility of acquiring 3-D data over a wide area.

On 29 November 2005 CETEMPS installed in L'Aquila a unit of DAVIS Vantage Pro2™ Plus Wireless Weather Stations. It consists of two components: the Integrated Sensor Suite (ISS) which houses and manages the external sensor array; and the console which provides the user interface, data display, A/D conversion, and calculations. The ISS and Vantage Pro2 console communicate via an FCCcertified, license-free frequency hopping transmitter and receiver. User-selectable transmitter ID codes allow up to eight stations to coexist in the same geographic area. The frequency hopping spread spectrum technology provides greater communication strength over longer distances and areas or weaker reception. The Wireless Vantage Pro2™ Plus weather station includes two additional sensors that are optional on the Vantage Pro2: the UV sensor and the solar radiation sensor. The console may be powered by batteries or by the included AC-power adapter. The wireless ISS is solar powered with a battery backup. Use WeatherLink™ for Vantage Pro2 to let your weather station interface with a computer, to log weather data, and to upload weather information to the internet.
