Jülich DATA 2020 This dataset is based on the 2016 field campaign BEST-ONE (Beijing winter fine particulate Study - Oxidation, Nucleation, and light Extinctions) and is a product of the International Joint Laboratory for Regional Pollution Control, Jülich, Germany, and Beijing, China. More specifically, this dataset is provided in order for users to replicate the results from the Gkatzelis et al. publication. It includes time-series of species in the gas- and particle-phase during measurements performed in Huairou, Northeast of Beijing, in the winter of 2016. Also, provided is the output of the Positive Matrix Factorization model analysis.
