Uncertainty estimation method:
AMS is calibrated against measurements of particle volume by an SMPS. Total uncertainty is influenced by errors in calibration, uncertainty in relative ionization efficiency values, and uncertainty in particle collection efficiency. Error is described further here: http://www.nature.com/articles/s41557-018-0002-2
