NCAR/EOL Quality Controlled Radiosonde Data (Upper Orange Grove)



This dataset contains the quality controlled radiosonde data collected by the NCAR/EOL Integrated Sounding System (ISS) that was located at the upper orange grove site in the center of the Vale do Cobrao during the Perdigao field project in 2017. This dataset includes sounding data from daily launches occurring at 00, 06, 12, and 18 local time, as well as select periods with 3-hourly launches, in EOL format. These data have been quality controlled and include a data quality report that include information on the project, the quality control techniques applied, and subsequent corrections.
