title: Horizon2020 [FORCeS] Puijo SMEAR-IV campaign data

description: 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.

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. 

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.). 

 

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. 

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.).

description: Data from the FORCeS 2020 measurement campaign at Puijo SMEAR IV tower and ground station.

The FORCeS project received funding from the European Union’s Horizon2020 research and innovation programme under grant agreement No 821205.

Measurment Period:

Sep - Nov 2020

Location:

2 sampling locations in Kuopio, Finland

1) Puijo SMEAR-IV station inside the Puijo observation tower on top of Puijo hill (File identifier and EBAS station code: FI0063R)

2) SMEAR IV ground station located at the foot of Puijo hill (File identifier SMEAR_IV_ground_Station)

Data from Puijo SMEAR-IV:



         meteorological parameters,

          atmospheric gasses (O3, NOx, SO2),

          black carbon (MAAP-5012 Thermo Fischer Scientific).

          particle number concentration and size distribution (DMPS).


Data from Ground Station:



         meteorological parameters, atmospheric gasses (O3, NOx, SO2),

          aerosol bulk properties (AMS, Aerodyne Research Inc.),

          particle number concentration and size distribution (SMPS, TSI Inc.).


File format:

The files names and format follow the EBAS data format (https://ebas-submit.nilu.no/).

Additional Station Information:

Both stations are located in a semi-urban environment. The Puijo SMEAR-IV station is located ~80m above ground and ~200m above the surrounding lake level in a forested area at the edge of Kuopio. The ground station was situated at the foot of Puijo hill at the edge of this forest/park area.

The SMEAR-IV station is regularly inside low level clouds forming at the Puijo hill. The ground station is always below the cloud layer.

The SMEAR-IV station has a dual inlet setup: total air (aerosol particles < 50 um at ambient conditions) and interstitial (aerosol particles < 1 um at ambient conditions). Particles are dried and measuerd at ~20-25C. When the station is inside a cloud, the total inlet captures both interstitial aerosol particles and cloud droplets (measured as their dried residuals). The interstial inlet only samples the interstitial particles. Information about the occurance of cloud events are availabe upon request.
