%X The ground synchronous observation of K & Ka band airborne microwave radiometer in the intensive observation area of Binggou basin on March 30, 2008 provides a basic data set for the inversion of snow microwave radiation characteristics and parameters, especially the discrimination of dry and wet snow. Observation contents include: 1) The parameters observed by snow characteristic analyzer include snow density, snow complex dielectric constant, snow volume water content, snow weight water content, etc. the measurement is carried out in sample plot bg-a. 2) Snow parameter observation, including snow depth observation, synchronous snow surface temperature observation during aircraft transit, layered snow depth temperature observation, snow particle size observation and snow density observation. The observation was carried out in 5 sample plots bg-a, bg-b, bg-f, bg-h and bg-i. There are 10 points measured by bg-a, 6 points measured by bg-b, 12 points measured by bg-f, 21 points measured by bg-h and 20 points measured by bg-i. The specific measurement methods and instruments used are as follows: dig the snow section at each measurement point, and evenly layer every 10cm from top to bottom. If the last remaining depth is more than 10cm but less than 15cm, it shall be divided into one layer. Measure the thickness, snow particle size, density and temperature of each layer respectively. The thickness of each layer is measured with a plastic ruler; Manual reading of snow particle size with hand-held microscope; Three random measurements for each layer; The density is calculated from the snow sample taken by the ring knife of each layer; The temperature is measured by the needle thermometer, and the temperature of each layer of snow is determined by the average value of two needle thermometers measured at the same time. At the same time, the snow surface temperature is measured simultaneously in sample I and sample h when the aircraft passes through.The dataset includes two f
