Cloud condensation nuclei measured at the Southern Great Plains observatory in autumn 2019

The enclosed dataset is the time series of the 6-hour time-averaged cloud condensation nuclei (CCN) concentrations, measured with 0.1%SS (supersaturation) and 0.2%SS at Southern Great Plains (SGP, 2019). The CCN-activated fraction (CAF) time series data for each %SS measured at SGP is also provided. The accuracy of CCN measurement is ±3%. The uncertainty in CAF is estimated as ± 6%.
