Horizon2020 [FORCeS] Puijo SMEAR-IV campaign data

<p>A 3 month long ambient measurement campaign at SMEAR-IV station (station code FI0063R; Kuopio, Finland; https://www.atm.helsinki.fi/smear/?page_id=85) with complimenting ground station measurements. Semi-urban environment. SMEAR-IV station measurement height is at 80m above ground.</p> <p>Measured quantities at SMEAR-IV: meteorological parameters, atmosheric gasses (O3, NOx, SO2), black carbon (MAAP-5012 Thermo Fischer Scientific), particle number concentration and size distribution data (DMPS). SMEAR-IV station has a switching double inlet set-up: whole air (ambient aerosol smaller than 50 um at ambient conditions), and interstitial (ambient aerosol smaller than 1 um at ambient conditions) which was utilised in black carbon measurements.&nbsp;</p> <p>Measured quantities at ground station: meteorological parameters, atmosheric gases (O3, NOx, SO2), particle number concentration and size distribution data (SMPS, TSI Inc.), and aerosol bulk proprties (AMS, Aerodyne Reserach Inc.).&nbsp;</p> <p>&nbsp;</p> <p>Additional data measured at the SMEAR-IV station: cloud condesation nuclei activation diameter (CCN counter, Droplet Measurement Technologies), aerosol particle bulk composition and properties (ACSM, Aerodyne Reserach Inc.), more detailed particle composition (FIGAERO-CIMS, Aerodyne Reserach Inc.), cloud droplet concentration, and visibility.&nbsp;</p> <p>Additional data measured at the ground station: cloud condesation nuclei activation diameter (CCN counter, Droplet Measurement Technologies), more detailed particle composition (FIGAERO-CIMS, Aerodyne Reserach Inc.), small oxygenated compounds, polar molecules, BTEX, PAHs, other aromatics (VOCUS, Aerodyne Reserach Inc.).&nbsp;</p> <p>Please contact creators for these data.&nbsp;</p> <p>&nbsp;</p> <p>This work was supported by the European Union&rsquo;s Horizon 2020 research and innovation program under grant agreement No. 821205 (FORCeS).</p>
