Data set of aerosol number concentration and particle size spectrum at Shiquanhe station in Ali area (2019)

The data set contains the number concentration and size distribution spectrum of particles in the atmosphere of Shiquanhe national climate station (32 ° 30'n, 80 ° 05'e, elevation 4278.6 m) in Ali Region. The instrument is tsi-3321 aerodynamic particle size spectrometer (APS), with 52 particle size channels. The observation period is from July 7, 2019 to August 2, 2019, and the time resolution is 5 minutes. The size distribution spectra of aerosol volume concentration and mass concentration can be obtained by using the data, aerosol spherical hypothesis and aerosol density, and then the characteristics of aerosol particle size distribution in the northwest of Qinghai Tibet Plateau can be studied.

Data file naming and use method

File name: the data file is stored in A21 file format. The file name is "2019-7-7. N.a21", and 2019-7-7. N represents the time when the first data file is generated, and the first day n is 0. After that, each day, a new data file is generated, and the n of the newly generated file will be increased by 1. For example, the file generated on July 9, 2019 is named 2019-7-7.2.a21.
Data reading method: the data file cannot be used directly. You need to open the aerosol instrument manager software to import the file. After selecting all the files, click file → export → select number and dwdlogdp in the units and weights tab → select row in the orientation tab, and click OK to output the number concentration particle size spectrum data in TXT format.
