This dataset contains vehicular dual polarization Doppler radar observation data from the Eighth Management Protection Area of Minle County Forestry Bureau in the middle reaches of the Heihe River in 2008 (with complex underlying surface and transitional zone characteristics)
The observation content is 250m × High quality continuous estimation data of bilinear polarization Doppler radar every 10 minutes on a 250m horizontal grid
Observation location: Liuba (38.73 ° N, 100.45 ° E, altitude 1668 meters), Ganzhou District, Zhangye City, Gansu Province. The observation time began on May 20, 2008 and ended on July 5, 2008
The purpose of the observation experiment is to explore the method of using radar joint observation and inversion of surface precipitation types and intensities in high cold regions using simultaneous precipitation particle drop spectrometer observations and surface precipitation encryption observations, and to establish a systematic and continuous radar observation dataset
The obtained echo parameter intensities include velocity V, spectral width W, intensity reflectance difference, differential transmission phase shift, ratio difference, correlation coefficient, and linear depolarization ratio Ldr
Autonomous production (instrument observation)
