A Quality Control Method of Automatic Weather Station

Abstract

The invention discloses an automatic meteorological station quality control method. Quality control is more accurately achieved through combination of multiple quality control algorithms; the quality control algorithms of an automatic meteorological station better meet localization requirements by adding the updating function of algorithm metadata. Compared with a traditional quality control algorithm, errors needed by prediction are greatly reduced, and prediction precision is improved.

Description

technical field [0001] The invention relates to a quality control method of an automatic weather station, belonging to the technical field of meteorological data quality control. Background technique [0002] Through the automatic weather station, the automatic collection, transmission, recording and processing of various meteorological elements can be completed, which greatly reduces the human input and risk of the collection work, and provides convenience for the meteorological service work. In recent years, with the rapid advancement of my country's surface meteorological modernization, the number of automatic weather stations in the country has exceeded 30,000. Due to fierce competition, some manufacturers have begun to try to add quality control functions in the central station software to ensure the quality of data and reduce the interference of erroneous data on weather forecasts. [0003] At present, the quality control algorithms used at home and abroad mainly incl...

Problems solved by technology

[0004] 1. The range of climate extremes is difficult to be precise: With the impact of global climate change, extreme weather and climate events occur frequently, and the fixed range of climate extremes is too large, which is useless; the range is too precise, and once extreme weather occurs, the real situation will be misjudged value;

[0005] 2. Analyzing on an annual scale, the premise of spatial consistency is difficult to meet

[0006] The above two problems make the automatic weather station fall into the difficulty of unsatisfactory real-time data quality control and difficult algorithm threshold upgrade
