CLIMODE QC Radiosonde Data


The CLIvar MOde Water Dynamic Experiment (CLIMODE) was a project designed to study the dynamics of ‘Eighteen Degree Water’ (EDW); the subtropical mode water of the North Atlantic. For this study NCAR/EOL deployed one Integrated Sounding System (ISS) on board the ship R/V Knorr. CLIMODE was conducted in the Atlantic Ocean, off the East coast of the United States during February and March, 2007. EOL deployed an Integrated Sounding System (ISS), including a UHF boundry layer wind profiler, a Radio Acoustic Sounding System (RASS) and a GPS Advanced Upper-air Sounding System (GAUS). There were a total of 150 radiosonde launches made, 148 of which are included in the final data archive. Two soundings were removed for lack of data.
