NCAR Integrated Sounding System deployment to the M2HATS field campaign

NCAR / EOL deployed the Integrated Sounding System (ISS) to the M2HATS field campaign. M2HATS (Multi-point Monin-Obukhov similarity Horizontal Array Turbulence Study) was a campaign led by Chenning Tong of Clemson University and Shane Mayor of Chico State University to examine turbulence in the convective boundary layer. The campaign was conducted near Tonopah, NV, from July to September, 2023. A range of instruments were deployed, including the ISS, ISFS (Integrated Surface Flux System), and MPD (MicroPulse DIAL lidar) from NCAR, the REAL lidar from Chico State University, UAS from the University of Oklahoma, and UAS and a Doppler wind lidar from the University of Virginia. The ISS included radar wind profilers (including the 449 MHz Modular Wind Profiler), RASS, radiosonde soundings, scanning Doppler wind lidars, CL61 depolarisation ceilometer, web cameras and surface meteorological sensors. This presentation will focus on some highlights of measurements from the ISS, as well as instrumentation, data processing and quality control issues from the deployment. The main focus of the study was boundary layer turbulence and winds, however tropical storm Hilary also passed very close to the site and observations from that unusual event will also be presented.
