Deposition on high altitudes

Updated 2017-10-12

The aim of this project is to measure the airborne deposition of acidifying and eutrophicating compounds (gaseous and particulate reduced and oxidised nitrogen and sulphur compounds) in air and precipitation over Sweden at high altitude. The results from this programme is used to calculate and model basic processes governing sources, atmospheric transport and sinks of atmospheric trace constituents. The observations are made at three stations. The measurements include particulate reduced and oxidised nitrogen and sulphur compounds in gaseous and particulate form in air and precipitation.

This is not a National Implementation Plan (NIP) project
Comments and additional information:

From 2002 project is a part of the Swedish generational goal "Natural Acidification Only and zero eutrophication". The measurements are database for for Multiscale Atmospheric Transport and Chemistry(MATCH) Model driven by Swedish Meteorological and Hydrological Institute (SMHI). The observation stations in the AMAP area are: Katterjåkk, Ropparudden, and Skorvfjället. The observations made at these stations are: (i) particles in the air (So4-S, NO3-N, NH4-N, Cl, Na, Ca, Mg, K; (ii) Gases (NH3-N, HNO3-N, SO2-S); (iii) deposition in open field (precipitation, H+, SO4-S, Cl, NO3-N, NH4-N, Ca, Mg, Na, K); (iv) deposition in forest (throughfall, H+, SO4-S, Cl, NO3-N, NH4-N, Ca, Mg, Na, K).

Methods & Procedures

Procedures and methodology used for, e.g., sampling and sample storage, sample pretreatment, extraction and analysis, including which laboratories are involved, references to methods employed, etc.

Concentrations of acidifying and eutrophicating compounds in the air are measured with a filterpack method. All analyses are performed at the accredited laboratory at IVL according to EMEPs recommendation.;
