Black carbon measurements

Aerosol black carbon (BC) concentration levels in the atmosphere are measured at five different background stations in Finland, with the longest data set from Hyytiälä. The continuous measurements are used to validate the climate model data.

Measurement details

Black carbon measurements in Finland are conducted with two different instruments: the AE 31 aethalometer (Magee Scientific) and the multi-angle absorption photometer (MAAP) (Thermo Scientific).

Measurement details from each station are shown in the table below.
