VERSION 1.0 (30 June 2017)
This dataset was constructed from the raw station SMPS/DMPS data for the work presented in Freud et al. (2017, doi:10.5194/acp-17-8101-2017). Detailed information about the individual sites, instrumental setup, filtration, quality control, homogenisation and harmonisation can be found there. For further inquiries, reports on errors, and if you like to use all or parts of these datasets in a new publication please let me know (Eyal Freud, eyal.freud@aces.su.se).
If you would like to use the raw data, please check the following sites first and contact the original data provider. If you can't find the data there, please contact me and I will connect you with the right person.
