Background
Raindrops are one of the results of the micro physical process and the comprehensive effect of a plurality of factors in the cloud, and cloud nuclei form raindrops and descend to the ground through the physical processes of condensation combination, collision crushing, upward airflow clamping, evaporation and the like. The raindrop has abundant micro-physical information in size, speed, spectral distribution, axial ratio, particle orientation and the like.

If the abnormal data are substituted for subsequent rainfall observation and analysis, the obtained rainfall physical parameters have errors.
Second, the quality of the raindrops can be directly judged by the size of the raindrops. However, the size of raindrops is affected by the problems of water drop aggregation on the surface of a sampling instrument and the like, abnormal data cannot be accurately removed, and even normal raindrop spectrum data can be misjudged as abnormal data, so that the problem that the abnormal data removal accuracy rate in the raindrop spectrum data is low in the radar quantitative measurement is caused.

The raindrop spectrum data set is a set of raindrop spectrum data in a sampling time period, and the raindrop spectrum data set comprises a first number of raindrop spectrum data. A first number of raindrop spectrum data is co-sampled over a sampling period of time for generating a set of raindrop spectrum data. Specifically, a laser raindrop spectrometer can be used for raindrop sampling operation to obtain a raindrop spectrum data set. The laser raindrop spectrometer samples through a horizontal laser beam generated by a sensor, when raindrops (whether in a liquid state or a solid state) pass through the laser beam, the output voltage attenuation and signal duration caused by shielding of the raindrops are recorded, the size and speed of the raindrops are calculated accordingly, the rainfall type and the raindrop quantity can be monitored in real time, and the rainfall intensity and the accumulated rainfall are calculated.
Optionally, the raindrop spectrum data acquired through the sampling operation is a two-dimensional table. The rows of the raindrop spectrum data correspond to the raindrop diameters, and the columns of the raindrop spectrum data correspond to the raindrop velocities. Specifically, the two-dimensional table corresponding to the raindrop spectrum data includes 32 rows and 32 columns.

In some embodiments, the execution subject determines a set of control thresholds. The control threshold value set comprises a rainfall raindrop speed threshold value and a rainfall raindrop quantity threshold value.
And step 203, generating a falling end speed set of rainfall raindrops and a quantity data set of the rainfall raindrops based on the raindrop spectrum data set.
In some embodiments, the execution subject generates a set of end-of-fall speeds of the raindrops and a set of quantity data of the raindrops based on the set of raindrop spectrum data. Optionally, for each raindrop spectrum data in the raindrop spectrum data set, a falling end speed of the raindrop spectrum data is generated to obtain the falling end speed set. Wherein the falling end speed is a two-dimensional table. Optionally, for each element in the raindrop spectrum data, an element in the two-dimensional table corresponding to the falling end speed of the element is generated by using the following formula, so as to obtain the falling end speed of the raindrop spectrum data:
wherein i represents a row count of the raindrop spectrum data, j represents a column count of the raindrop spectrum data,

Optionally, a target raindrop spectrum data set is generated, where the target raindrop spectrum data set is an empty set. In the initial state, no raindrop spectrum data exists in the target raindrop spectrum data set. An empirical speed value is determined. Specifically, the empirical speed value may be obtained by analyzing the speed value of the raindrops in the history of the specific region. Specifically, the empirical speed value may be determined using a statistical averaging method.
Optionally, a quality index set is generated. Wherein the quality index has a value of 0.

The optional contents in the above step 202 and step 204 are: the technical content of removing abnormal data by using the rainfall raindrop speed threshold and the rainfall raindrop quantity threshold is taken as an invention point of the embodiment of the disclosure, and the technical problem mentioned in the background art is solved, namely that the quality of the rainfall raindrops can be judged directly through the size of the raindrops. However, the size of raindrops is affected by the problems of water drop aggregation on the surface of a sampling instrument and the like, abnormal data cannot be accurately removed, and even normal raindrop spectrum data can be misjudged as abnormal data, so that the problem that the abnormal data removal accuracy rate in the raindrop spectrum data is low in the radar quantitative measurement is caused. ". Factors that lead to a lower accuracy of the quality control of the raindrop spectrum data tend to be as follows: the process of collecting rainfall raindrops by the raindrop spectrum is easily interfered by various factors, and the problem of low quality control accuracy in radar quantitative measurement is often caused by processing data according to a single size, speed and the like. If the above factors are solved, the effect of improving the quality control accuracy of the raindrop spectrum data can be achieved. To achieve this effect, the present disclosure introduces a dual threshold control method. First, a rainfall raindrop speed threshold and a rainfall raindrop number threshold are determined. Then, a falling end speed set of the rainfall raindrops and a quantity data set of the rainfall raindrops are generated according to the raindrop spectrum data set in the sampling time period. And finally, generating a quality index set of the raindrop spectrum data, which can represent the speed quality index and the quantity quality index of the raindrop spectrum data quality, based on the control threshold value set, the last falling speed set and the quantity data set. Abnormal data are removed according to the quality index set controlled by the double thresholds, and the speed and the number of raindrops can be considered at the same time, so that the accuracy of data processing is improved, the accuracy of removing the abnormal data can be improved during radar quantitative measurement, the quality control accuracy of raindrop spectrum data is improved, and the technical problem two is solved.
