CE318 solar spectrophotometer atmospheric parameter data: the atmospheric parameters measured by the solar spectrophotometer produced by cimel company in France. The survey site is the roof of the resort activity room. Main coverage types of underlying surface: crops and forests, height = 1526m, specific coordinate positions in the document. CE318 solar spectrophotometer can inverse the optical thickness, Rayleigh scattering and aerosol optical thickness of non water vapor channel through direct solar radiation measurement data. The water vapor content of atmospheric column can be obtained from 936nm measurement data of water vapor channel, and the horizontal visibility can also be derived from CE318 data. CE318 of Beijing Normal University is used in this measurement, which can provide the optical thickness of five bands: 1020nm, 936nm, 870nm, 670nm and 440nm, and the water vapor content of the atmospheric column can be retrieved from the 936nm measurement data.\n

Specific emissivity data: the W-type specific emissivity observer was used to measure the specific emissivity data of bare soil and vegetation in huazhaizi desert sample plot 1 on that day. Assuming that the environment is stable in the measurement time period, the instrument calculates the specific emissivity of ground objects by changing the four measurements of \"cold and hot\" radiation environment. Therefore, in order to obtain the specific emissivity data of ground objects, it is necessary to measure in sequence: cover with gold plate; No capping and gold plate; Stamped without gold plate; No cover, no gold plate.
