Embodiment Construction
[0033] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.
[0034] This embodiment selects the observation data of the national surface weather stations at 16:00 on June 22, 2017, which contains 4053 valid weather station observation records.
[0035]Step 1) Read the above weather station observation data, extract the weather station attributes and meteorological element information needed to check the correctness of the relative humidity data, and form a data set, which may be defined as: DS[ID,La,Lo, RH, VP, T], wherein, ID represents the numbering of weather station, is used to distinguish different weather stations; La and Lo represent respectively the latitude and the longitude of weather station location geographical position; RH represents relative humidity, and it is that the present invention carries out data correct Meteorological elements for sex check; VP means water pressure; T means ambie...

The invention discloses the inspection method of a ground meteorological observation station observation relative humidity value. In the method, through a logical relationship among relative humidity,an ambient temperature and water vapor pressure, an abnormal meteorological station record is removed so that the adverse effect of error data on spatial relationship interpolation inspection is effectively reduced. When different retrieval radiuses are sought and established, through a function relationship between the relative humidity and the average relative humidity calculated by a spatial interpolation and the relative humidity of the inspected meteorological station, a deviation between the relative humidity and actual relative humidity when a geographic position infinitely approachesthe inspected meteorological station under an ideal condition is calculated, and then a correctness determination algorithm is established. The method has the advantage that smooth processing is performed on the differences of the external factors of the different meteorological stations, such as an underlying surface, the ambient temperature and the like so that the purpose of improving the accuracy and the reliability of the relative humidity data of the meteorological station based on spatial relationship interpolation inspection is finally reached.
Description
technical field [0001] The invention relates to the field of atmospheric detection, in particular to a method for checking relative humidity values observed by ground meteorological observation stations. Background technique [0002] The ground meteorological observation station (hereinafter referred to as the weather station) is a device used to observe real-time weather phenomena such as relative humidity, temperature, atmospheric pressure, and precipitation. With the improvement of the sensor hardware level and the rapid development of wireless networks, today's weather stations have the characteristics of fast data collection, timely transmission, strong real-time performance and high degree of automation, and can complete the collection and data collection of various meteorological elements in the geographical location in a timely manner. transmission, data preprocessing, etc. However, due to the limitations of objective conditions such as the extreme geographical en...
