Wind profiler observations from the DYNAMO Field Campaign

NCAR / EOL deployed two wind profilers to the Indian Ocean for the DYNAMO (Dynamics of the Madden-Julian Oscillation) field campaign in 2011/2012. The wind profilers were deployed with Integrated Sounding Systems (ISS) as part of an NSF facility request lead by PIs from the University of Miami, Colorado State University and other institutions . One system was deployed on the island of Diego Garcia and the other on-board the R/V Revelle, along with a wide variety of other instrumentation from many other groups. The wind profilers were 915 MHz boundary layer DBS wind profiler radars, and were deployed with ISS instruments such as radiosonde soundings, GPS integrated water vapor, basic met sensors and sky cameras. The Diego Garcia ISS also included RASS, a surface met station and a ceilometer. Both wind profilers observed MJO related activity along with more localized phenomena. The Diego Garcia wind profiler saw evidence of island heating effects. The Revelle wind profiler was susceptible to sea clutter in the lower range gates, and a correction routine is being devised.
