Embodiment 1
[0047] like figure 1 as shown, figure 1 A flow chart of a method for identifying the quality of rainfall observation values in real time provided by an embodiment of the present invention, the method includes:
[0048] S101: Obtain historical rainfall observations and corresponding historical radar quantitative precipitation estimates within a preset time period;
[0049] S102: Divide the historical rainfall observations into a plurality of rainfall grade intervals according to the rainfall value, and determine the error distribution range of the historical rainfall observations and the corresponding historical radar quantitative precipitation estimates in each rainfall grade interval ;
[0050] S103: Acquire real-time rainfall observations and corresponding real-time radar quantitative precipitation estimates, and determine the error distribution range corresponding to the rainfall grade interval to which the real-time rainfall observations belong;
[0051] S104: Determi...
Embodiment 2
[0099] For ease of understanding, such as figure 2 As shown, this embodiment also provides a system for identifying the quality of rainfall observations, including an acquisition unit, a distribution range determination unit, and an identification judgment unit;
[0100] The acquisition unit is used to obtain historical rainfall observations and corresponding historical radar quantitative precipitation estimates within a preset time period, and obtain real-time rainfall observations and corresponding real-time radar quantitative precipitation estimates;
[0101] Distribution range determination unit: used to divide the historical rainfall observations into a plurality of rainfall grade intervals according to the rainfall value, and determine the historical rainfall observations and corresponding historical radar quantitative precipitation estimates in each rainfall grade interval The error distribution range of the value; determine the error distribution range corresponding t...
