M2HATS: ISS Radar Wind Profiler and RASS Data Products

Summary

449 MHz, 915 MHz Profiler winds and moments, and RASS virtual temperature collected by the EOL/Integrated Sounding System team during the M2HATS (Multi-point Monin-Obukhov similarity horizontal array turbulence study) field campaign in Tonopa, Nevada. All data files are in netCDF format.

915 MHz data are availlable through both standard and NIMA (NCAR Improved Moments Algorithm) processing. Moments are separate files provided by NIMA processing. Curtain plots of daily winds from the standard processing have been included.

RASS virtual temperature are 5-minute averages run every half hour (in between times the profiler was in winds mode). The moment files are for each spectral averaging period (dwell), and are at about 20 second time steps.
