Aerosol Optical Property Dataset of Tibetan Plateau by ground-based observation (2021)

Aerosol Optical Property Dataset of Tibetan Plateau by ground-based observation (2021)

The ground-based observation dataset of aerosol optical properties over the Tibetan Plateau was obtained by continuous observation with a Cimel 318 sunphotometer, involving two stations: Qomolangma Station and Nam Co Station. These products have taken the process of cloud detection. The data cover the period from January 1, 2021 to December 31, 2021, and the time resolution is daily. The sunphotometer has eight observation channels from visible light to near infrared, and the central wavelengths are 340, 380, 440, 500, 670, 870, 940 and 1120 nm, respectively. The field of view angle of the instrument is 1.2°, and the sun tracking accuracy is 0.1°. Six bands of aerosol optical thickness can be obtained from direct solar radiation, and the accuracy is estimated to be 0.01-0.02. Finally, AERONET unified inversion algorithm was used to obtain the aerosol optical thickness, Ångström index, aerosol particle size distribution, single scattering albedo, phase function, complex refraction index and asymmetry factor.

File naming and required software

The AOD dataset is stored in text format, and the file name is "yymmdd.txt", where yy stands for year, mm stands for month, dd stands for date. For example, 210101.txt represents this ASCII file describing the AOD information on the Tibetan Plateau on the first day of January 2021.
