NOAA CSL PUMAS
The NOAA CSL Pick-Up based Mobile Atmospheric Sounder (PUMAS) is a microjoule class, scanning micro-pulse Doppler lidar (MicroDop) installed in the bed of a pickup truck that measures vertical profiles of horizontal and vertical winds, turbulence and aerosol backscatter intensity while driving at highway speeds. These variables can be used to infer boundary layer height. PUMAS will complement the airborne Doppler lidar system installed on the NOAA Twin Otter to provide additional constraints on transport processes during research flight days in support of airborne mass balance measurements.
NOAA CSL TOPAZ
The NOAA CSL Tunable Optical Profiler for Aerosol and oZone (TOPAZ) lidar utilizes Differential Absorption Lidar (DIAL) to measure vertical profiles of ozone and aerosol backscatter. TOPAZ is part of the NASA Tropospheric Ozone Lidar Network (TOLNet) for ground-based profiling of tropospheric ozone, validation of satellite ozone measurements, and a long-term data record for ozone vertical profiles. TOPAZ has a 2-axis zenith and azimuth scanner to enable measurements from a few meters above ground level through its maximum range of 6–8 km. TOPAZ will make intensive measurement during daylight hours from the NOAA David Skaggs Research Center (DSRC) in Boulder on flight and drive days during the two-week measurement period. NOAA CSL will also continuously operate a stationary ground based Doppler lidar alongside TOPAZ at the DSRC site during the two-week measurement period to provide additional context and constraint to flight days.
NOAA CSL Mobile Laboratory
The NOAA CSL Mobile Laboratory is an instrumented Ford Transit van that has recently been acquired and upgraded to accommodate measurements of detailed chemical composition using a suite of instruments that include greenhouse gases, nitrogen oxides, speciated VOCs, speciated oxidized nitrogen, particulate matter size distributions and total mass, meteorological parameters and other data. The mobile lab will participate in the Utah Summer Ozone Study (USOS) in the summer of 2024 in Salt Lake City, Utah, which will begin immediately following AMMBEC. Integration of instrumentation will take place in spring 2024. Test drives of the mobile lab may contribute to the data set for AMMBEC during the first two weeks of July 2024, but this contribution will depend on the availability of this platform for the Colorado measurements.
