CAREER/ROCS QC Radiosonde Dataset


The purpose of the Research on Convective Snows (ROCS) project is to determine the characteristics of clouds that produce weather events where snow is accompanied by lightening and thunder. During the project, 47 radiosondes were launched from various locations throughout the Central United States between February 8, 2005 and March 18, 2005. The final radiosonde data set consists of 44 quality controlled ascending soundings and 4 descending soundings. Three soundings were removed from the final archive because the radiosondes never left the ground. Two of the soundings experienced a loss of the radiosonde signal at some point during the flight. For each, the signal was eventually recaptured and the data were stored in new sounding files. During post-processing we identified these “extra files” and merged them with the data collected before the signal loss.
