ultrafine aerosol size distribution collected at Gruvebadet, Ny Alesund, Svalbard

At Gruvebadet aerosol size distribution are measured with a scanning mobility particle sizer spectrometer TSI SMSP 3034, in the range 10-487 nm), and with a Aerodynamic particle sizer TSI APS 3321 i the range 500-20000 nm) since 2010. Data are collected with a frequency of 10 minutes.

SMPS 3034 collect data in 54 size channels centred at

Dsmps=(micron) (54 channels)

For each channel of SMPS and APS the quantity DN/DlogD is provided

Data are stored in monthly files, separately for SMPS, that contains columns of collected measurements in the following order:

column 1 Date time (YYYY-MM-DD HH:MM:SS) in UTC

column 2 DN/DlogD 1st channel

......

column XX DN/DlogD last channel

where XX is

55 for SMPS 3034 (fine particles)

52 for APS 3321 (coarse particles)

We have holes in the data due to instrument failures. In particular we have few months without measurements (empty files).

For SMPS they are: 01/2016, 02/2016, 06-12/2016, 01/2017, 11/2017, 12/2017, 01/2018
