%X In order to cooperate with the dual polarization Doppler radar for observation, multiple rain cones are arranged in the hydrological test area of the upstream cold region and the hydrological test area of the Middle Arid Region to strengthen the observation. The upstream data is not listed as a separate data set due to poor quality. The observation of the middle reaches is composed of 29 rg3-m automatic collection tipping bucket rain gauges, of which the northernmost rain gauge is 100.36 ° E; 39.16 ° n, and the position of the rainfall tube at the southernmost end is 100.34 ° E; 38.61 ° n, the position of the easternmost rain tube is 100.62 ° E; 38.87 ° n, and the position of the rain gauge at the westernmost end is 100.26 ° E; 38.82°N。 Observation time: r02-r09 rain gauge starts from May 18, 2008 to October 9, 2008, and r10-r30 rain gauge starts from May 26, 2008 to October 9, 2008. The main technical indicators are as follows:(1) Water bearing diameter: 165mm × 254mm(2) Temperature measurement range: 0 ° C - + 70 ° C(3) Resolution: 0.2mm(4) Measuring range: 0-320cm(5) Measurement accuracy: 1%
