Abstract

The field campaign of DYNAMO/CINDY2011 took place in the central equatorial Indian Ocean between September 1, 2011 and January 5, 2012. The experiment was primarily designed to improve understanding of the Madden-Julian oscillation (MJO) in the region. Observations of vertical moisture profiles, cloud structure, precipitation processes and the planetary boundary layer are necessary to improve understanding of MJO initiation. A number of remote sensing instruments, including NCAR's S-PolKa (dual-wavelength S-and Ka-band) radar and the University of Miami's microwave radiometer, were deployed to estimate water vapor and cloud structure. These instruments were collocated and scanned a common volume of the troposphere at various azimuth and elevation angles. The University of Miami's microwave radiometer performed brightness temperature measurements at 23.8 GHz, affected mostly by water vapor, and at 30.0 GHz, primarily sensitive to cloud liquid water. These measurements were performed continuously to estimate slant water path and liquid water path during various weather conditions, including clear and cloudy skies, as well as precipitation of various intensities.
