Puijo SMEAR IV Kuopio - Nephelometer, aerosol light-scattering coefficients, 2006-2011 (IDA)

Abstract

Nephelometer and aerosol light-scattering coefficients data measured through total (tot) and interstitial (int) inlets at Puijo SMEAR IV station in Kuopio, Finland. Data for years 2006-2011. See detailed description: https://avaa.tdata.fi/web/smart/smear-iv.

Data contains files for both inlets (tot and int):

* PUI_neph_int_2006_data.csv * PUI_neph_int_2007_data.csv * PUI_neph_int_2008_data.csv * PUI_neph_int_2009_data.csv * PUI_neph_int_2010_data.csv * PUI_neph_int_2011_data.csv * PUI_neph_tot_2010_data.csv * PUI_neph_tot_2011_data.csv

The files have the following columns (column_name: description; [unit]):

* Year, Month, Day, Hour, Minute, Second: Sample time (UTC +2), [] * quality: Quality parameter; [] * coeff_scat_blue: Aerosol scattering coefficient in blue; [1/Mm] * coeff_scat_green: Aerosol scattering coefficient in green; [1/Mm] * coeff_scat_red: Aerosol scattering coefficient in red; [1/Mm] * coeff_scat_blue_backscat: Aerosol back scattering coefficient in blue (backscatter); [1/Mm] * coeff_scat_green_backscat: Aerosol back scattering coefficient in green (backscatter); [1/Mm] * coeff_scat_red_backscat: Aerosol back scattering coefficient in red (backscatter); [1/Mm] * scattering_from_last_zero_blue: Aerosol scattering value from last zero (blue); [1/Mm] * scattering_from_last_zero_green: Aerosol scattering value from last zero (green); [1/Mm] * scattering_from_last_zero_red: Aerosol scattering value from last zero (red); [1/Mm] * scattering_from_last_zero_blue_backs: Aerosol back scattering value from last zero (blue backscatter); [1/Mm] * scattering_from_last_zero_green_backs: Aerosol back scattering value from last zero (green backscatter); [1/Mm] * scattering_from_last_zero_red_backs: Aerosol back scattering value from last zero (red backscatter); [1/Mm] * rayleigh_scattering_from_last_zero_blue: Rayleigh scattering value from last zero (blue); [1/Mm] * rayleigh_scattering_from_last_zero_green: Rayleigh scattering value from last zero (green); [1/Mm] * rayleigh_scattering_from_last_zero_red: Rayleigh scattering value from last zero (red); [1/Mm] * pressure_baro: Barometric pressure (mbar); [mbar] * temperature_sample: Sample temperature (degrees K); [K] * temperature_inlet: Inlet temperature (degrees K); [K] * RH: Relative humidity (%); [%] * pressure_blue: Pressure in millibar (blue); [mbar] * temperature_blue: Sample temperature in degrees K (blue); [K] * pressure_green: Pressure in millibar (green); [mbar] * temperature_green: Sample temperature in degrees K (green); [K] * pressure_red: Pressure in millibar (red); [mbar] * temperature_red: Sample temperature in degrees K (red); [K]

Interstitial (int) and total (tot) inlets:

Sample air for the instruments is drawn through two parallel sampling lines: interstitial (int) and total (tot) inlets:

* interstitial inlet (int) is equipped with an impactor with a 10-µm cut-off size followed by a cyclone with a 1.0-µm cut-off size (2.5 µm before 20 November 2009) * total air inlet (total) with heated sampling lines and snow-hood to dry the cloud droplets (cut-off size 40 µm when the wind speed is below 20 m/s)

This two-inlet setup enables simultaneous interstitial and total air (interstitial + cloud drop residual) measurements when the tower is covered by clouds.

The size of data: ca. 14 MB.
