AMOLITE  

Definition

  • Climate Change Canada (ECCC) has recently developed a fully autonomous, mobile LIDAR17 system called AMOLITE (Autonomous Mobile Ozone LIDAR Instrument for Tropospheric18 Experiments) to simultaneously measure the vertical profile of tropospheric ozone, aerosol19 and water vapor (night time only) from near ground to altitudes reaching ten to fifteen20 kilometers. This current system uses a dual laser, dual LIDAR design housed in a single21 climate-controlled trailer. Ozone profiles are measured by the DIfferential Absorption22 LIDAR (DIAL) technique using a single 1 m Raman cell filled with CO2. The DIAL23 wavelengths of 287 nm and 299 nm are generated as the second and third Stokes lines24 resulting from stimulated Raman scattering of the cell pumped using the fourth harmonic of a25 Nd:YAG laser (266nm). The aerosol LIDAR transmits three wavelengths simultaneously26 (355 nm, 532 nm and 1064 nm) employing a detector designed to measure the three27 backscatter channels, two nitrogen Raman channels (387 nm and 607 nm), and one cross-28 polarization channel at 355 nm. In addition, we have added a water vapor channel arising29 from the Raman-shifted 355nm output (407nm) to provide nighttime water vapor profiles. (en)
