NCAR/EOL R/V Investigator 915 MHz Radar Wind Profiler Products



Quality-controlled 915 MHz profiler winds and vertical beam moments data operated by the NCAR/EOL Integrated Sounding System (ISS) for the SOCRATES / CAPRICORN field campaign. ISS operated a radar wind profiler on board the CSIRO RV Investigator.  The primary voyage (CSIRO designation: IN2018_V01) for this deployment set sail from Hobart, TAS, Australia on 11 Jan 2018 into the Southern Ocean and concluded back in Hobart on 22 Feb 2018.  A shakedown, test and training cruise (IN2017_E04) took place off the east coast of Tasmania Dec 7 - 11, 2017.

The LapXM moment data were processed by EOL software (IDL to generate wind estimates corrected for ship motion, course and heading, partly based on the methods of Johnston (2014). These data were then quality-controlled through the NCAR Improved Moments Algorithm (NIMA). Some gaps in the NIMA-processed data have been filled in with the original LapXM-processed data. 

This dataset currently includes a Preliminary Data Report that does not reference the NIMA quality-control.
