 Lab Tours
The LACO laboratory facilities are
still under development and is currently composed of 5 main components:
_________________________________________________________________________________________________________
1-
The Optical Calibration Facility (304B –
back room):
Include
a semi-clean room with continuous HEPA and hydrocarbon air filtration,
containing a 20” integrating sphere with 4 discrete light levels, and a
variable attenuator for continuous intermediate radiances. The facility
will soon have a polarization calibrator (currently under construction in
the rapid prototype lab) which will accurately generate partially polarized
light. This lab also supports the development of sensitive optical
instrumentation that requires special care and relatively clean
environment.

1-
The Rapid Prototype Lab (304B – front
room)
This lab
supports the development of in situ instrumentation for the measurement of
aerosol and cloud particles, as well as the development of cameras and
remote sensing sensors.
_________________________________________________________________________________________________________
2-
The Wet Chemistry and Aerosol Lab (room
006 in the basement)
Support
the generation, conditioning and analysis of in situ aerosols, water and
ice cloud particles. This facility is composed of several in situ aerosol
generation and analysis tools, supporting the real time measurement of
chemical and physical properties of aerosol particles. Here we can
manipulate dry and wet aerosols and measure their properties as a function
of relative humidity.
   
 
________________________________________________________________________________________________________
3-
The Aerosol Filter Handling and Sampling
Lab (room 405)
Support
the handling, preparation, analysis, and storage of aerosol filters. This
lab includes a 0.1ug micro-balance for aerosol gravimetric analysis and
supports the deployment aerosol samplers and filters for field campaigns
and permanent stations.
_________________________________________________________________________________________________________
4-
The Filter sampling Station (roof of the
Physics Building)
In
addition to the Improve Sampling station (by Dr. Hoff’s Group), LACO has a
PM10/PM2.5 sampling system for collecting Nuclepore Filters. The inlet
system was implemented as part of the Phys650 – Experimental Atmospheric
Physics Course and managed by the students. The collected samples were
submitted to gravimetric analysis, electron microscopy imaging, and X-ray
microanalysis.
