%X Synchronous snow parameter observation can provide a basic data set for snow temperature inversion and verification of airborne satellite remote sensing data. Observation contents include: 1) Snow parameters were observed at the time of satellite transit, Beijing time (BJT) on March 19, 2008 (12:40-13:00). The observation is carried out in bg-b sample plot, which is divided into 4 observation groups, with 16 points in each group, a total of 64 observation points. Observation variables include: snow depth (ruler measurement, 5 snow depth data are randomly observed at each point); Snow surface temperature (measured by hand-held infrared thermometer and observed at random for many times); Layered snow depth temperature (measured by needle thermometer, observed in layers according to 10cm, and observed twice at each measuring point); Snow particle size (measured by hand-held microscope, observed in layers of 10cm, and repeated observation for 3 times at each measuring point). 2) The observed variables include snow density, snow complex dielectric constant, snow volume water content, snow weight water content, etc. The measurement is carried out in bg-a sample plot, with an automatic observation point to cooperate with spectrometer observation. 3) Snow spectral observation (ASD spectrometer), see GPS record file for the location of observation points. 4) Snow albedo observation (measured by portable albedo meter) was carried out in bg-a sample plot. This data set includes two folders: original data and preprocessed data.
