- •
Firn core decontamination is proved to be efficient for all the ions except ammonium.
- •
Post-depositional storage effects are found for MSA, NO3−, NH4+.
- •
Relatively high accumulation rate allows preservation of nitrate and MSA.
- •
Undisturbed deposition allows annual snow layer counting by NO3−, nssSO42 − and MSA.
- •
Spatial variability is lower than temporal variability at 5% significance level.
