Note:

Two versions of the AMS non-refractory mass concentration data are included. They are identical with the exception of a few days in which the size distributions grew so large that the spilled past the upper end of the AMS transmission curve. The first version of the data has been corrected for this loss using data from a collocated UHSAS instrument. This correction is designed to account for larger particles, near 1 micron diameter, that are lost due to sub-optimal transmission through the AMS aerodynamic lens. The second version of the data is not corrected for such transmission loses. Please contact the data managers if further information is needed (patrick.hayes@umontreal.ca and jose.jimenez@colorado.edu), or see Hayes et al. J. Geophys Res.-Atmos. 2013, 118, 9233, supporting information Section B. Note that a corrected version of chloride data is not included due to sensitivity limitations
