This data set contains rawinsonde profiles from the GPS Advanced Upper-air Sounding system (GAUS) archived during the Rain in Cumulus Over the Ocean (RICO) project. During the Rain In Cumulus Over the Ocean (RICO) project 183 radiosondes were launched from various locations in Barbuda between December 7, 2004 and January 24, 2005. The final radiosonde dataset consists of 144 quality controlled ascending soundings and 92 descending soundings. Twenty-three soundings were removed from the final archive because the radiosondes never left the ground. Twenty of the soundings experienced a loss of the radiosonde signal at some point during the flight. For sixteen of these, the signal was eventually recaptured and the data were stored in new files. During post-processing we identified these ?extra files? and merged them with the data collected before the signal loss. These data are provided as is without any Quality Control performed by NCAR/EOL.
