Objective
LOTOS (Lower Troposphere Observing System) 2021 is the first NCAR/EOL field experiment to test the proposed sensor network. Data collected from surface and towered measurements, radar wind profilers, wind lidars, and MicroPulse DIAL will be combined to develop and test algorithms that LOTOS will use to derive data products within the boundary layer. A proposed LOTOS component is the AERI (Atmospheric Emitted Radiance Interferometer) instrument that the University of Oklahoma operates as part of their CLAMPS (Collaborative Lower Atmospheric Mobile Profiling System) platform. In addition, the University of Colorado will use their UAS to execute fly-by’s over the multi-level flux tower for an intercomparison study.
