The timescale is EDC2, and the accumulation rates used to calculate flux also derive from EDC2. Non-sea-salt concentrations were calculated. We calculated ssNa and nssCa assuming a Ca/Na weight ratio of 0.038 for marine aerosols and 1.78 for the average crust. nssSO42- was derived assuming a SO42-/N...

Summary: | The timescale is EDC2, and the accumulation rates used to calculate flux also derive from EDC2. Non-sea-salt concentrations were calculated. We calculated ssNa and nssCa assuming a Ca/Na weight ratio of 0.038 for marine aerosols and 1.78 for the average crust. nssSO42- was derived assuming a SO42-/Na ratio in marine aerosol of 0.1 (appropriate for a sea ice surface, but note that the use of a traditional sea water ratio of 0.25 would not affect the results significantly).Data presented in Wolff et al. (2006) were all too high by 8.3% because of an error with the accumulation rates: these are the corrected values. ... |
