  Mobile Laboratory

      We operate a mobile laboratory to: (1) quantify emissions from various anthropogenic sources, (2) study tropospheric photochemistry, (3) quantify local to regional contributions to O3 production, and (4) provide a comparison to regional photochemical modeling results. The laboratory houses the following instrumentation:

  • Thermo O3
  • Thermo NO & NO2 (Blue Light Converter)
  • Thermo NOy
  • Thermo SO2
  • Los Gatos CO
  • Metcon JNO2
  • Tekran 2537B Hgo + Gaseous Oxidized Hg
  • Picarro G2232i CH4, CO2, H2O, 13δC in CH4
  • Picarro G2201i CH4, CO2, H2O, 13δC in CH4 and CO2
  • PTR-MS (IONICON Analytik Austria)) oxygenated VOCs (OVOCs: methyl vinyl ketone (MVK) plus methacrolein (MACR), methanol, acetone, methyl ethyl ketone (MEK), acetaldehyde, and acetic acid), and the aromatic compounds benzene, toluene, and C8 and C9 aromatics
  • Aerodyne TOM-AMS (R. Griffin - Rice University)
  • Video Cameras 5 directions (horizontal and vertical)
  • RM Young Meteorological Sensors
  • GPS


      We participated with funding from AQRP/TCEQ in the NASA DISCOVER-AQ campaign in Houston during the month of September 2013. The mobile laboratory operated 24/7 from August 29 to September 30. Preliminary results for gaseous elemental Hg are shown in the figure below:

      We also studied CH4 emissions from a large landfill in northeast Houston. This is depicted in the figure below:
