VOCALS: IMARPE R/V Jose Olaya GAUS Radiosonde Data

Summary

During the VAMOS Ocean-Cloud Atmosphere-Land Study (VOCALS) campaign, an NCAR/EOL GPS Advanced Upper-Air Sounding (GAUS) system was deployed. This dataset is from the system located on board the Instituto del Mar del Peru (IMARPE) ship R/V Olaya, and was conducted from September 30 to October 17, 2008. A total of 133 high quality radiosonde soundings were collected from the R/V Olaya along the coast of Peru. The site used Vaisala RS92 radiosondes with GPS windfinding. These data were processed by NCAR/EOL and converted to the EOL sounding composite format.
