The ALVICE mobile laboratory contains a suite of instruments with major focus on water vapor measurements. The 40' trailer contains a Raman-Rayleigh-Mie lidar that measures water vapor, aerosol, depolarization, cloud liquid and ice water, rotational-Raman temperature. The trailer contains ground station equipment for launching Vaisla and Intermet radiosondes as well as the Cryogenic Frostpoint Hygrometer. The ground station equipment for receiving the NOAA Frostpoint Hygrometer also exists in the trailer. A SuoimiNet GPS station travels with the trailer to provide total column water measurements. There is also a ventiled surface reference station for continuous NIST traceable T, P, RH measurements and also for performing pre-launch radiosonde accuracy studies. The laser used is a Continuum 9050 laser with nominal output of 17.5W at 355 nm. Daytime water vapor profiles are available every 3 minutes to an altitude of 4-5 km. Nighttime water vapor profiles extending to the lower stratosphere are possible under clear viewing conditions with several hours of data acquisition. Measurement campaigns in which the ALVICE system has participated include MOHAVE-II (2007), N_WAVES-2009, MOHAVE-2009, WAVES-2011, UWO_2012. The WAVES campaigns are based at Beltsville.
