Description

Fog Monitoring in the Mongstad area in Fall 2012 Fog sampling and characterization in the Mongstad Area (Norway) A major unknown in the environmental impact evaluation of the Carbon Capture Plant (CCP) in Mongstad is the local fog and cloud chemistry. Amines have a high tendency to partition into atmospheric droplets and there is strong indication that a large fraction of the atmospheric processing of the amines emitted from the CCP will happen in the aqueous phase. While precipitation chemistry can be used as a first approximation, a number of studies with simultaneous precipitation and fog/cloud chemistry measurements showed substantial differences, including acidity and major ion concentration variations of 1-2 orders of magnitude. As a result the worst case scenario modeling has an inherent uncertainty as local fog chemistry is not well constrained in the area around Mongstad. Background levels of nitrosamines and amines in fog and cloud droplets have not been measured until now in the region of Mongstad. Measurement of the fog/cloud chemical composition (e.g. with respect to acidity and nitrite levels) is necessary for the impact evaluation of both the test centre Mongstad (TCM) and the full-scale CCP at Mongstad (CCM) and has been recommended in the Summary Report of the CCM project on aqueous phase chemistry by SINTEF. Here we propose that Arizona State University (ASU) contributes to the NILU air quality monitoring efforts by providing fog samplers and doing part of the field work to collect fog and ground based cloud samples and analyze them.
