Problems solved by technology

[0003] However, we also clearly see that compared with developed countries, there are still many gaps in the construction and operation guarantee of my country's marine meteorological observation system, and there are still some gaps between scientific research and actual business needs, especially in anchorage In terms of buoy observation, data quality control is still blank, causing certain troubles to applications and servers

Embodiment 1

[0085] The preset algorithm is the absolute deviation algorithm, and the expression is:

[0086]

[0087] Among them, X M Denoted as the pattern data, X N Expressed as the comparison data or the correction data, M represents the total number of anchored buoy stations, N represents the total number of times, i is the number of anchored buoy stations, j is the number of times, the absolute deviation value of the correction data When it is smaller than the absolute deviation value of the comparison data, the climatology threshold value is positive correction, otherwise it is negative correction.

Embodiment 2

[0089] The default algorithm is the correlation coefficient algorithm, and the specific expression is:

[0090]

[0091] Among them, X M Denoted as the pattern data, X N Expressed as the comparison data or the correction data, M represents the total number of anchored buoy stations, N represents the total number of times, i is the number of anchored buoy stations, j is the number of times, and the correlation coefficient of the correction data is greater than When the correlation coefficient of the comparison data is used, the climatology threshold value is positively corrected, otherwise it is negatively corrected.

[0092] In any of the above embodiments, preferably, the mode data is data observed by the anchor buoy station in GRAPES mode and / or EC mode.

[0093] In this embodiment, the visibility data of GRAPES was not obtained due to objective reasons, so the EC mode data was used for comparison with the anchored buoy data. It should be noted that, in order to avoid ...

Abstract

The invention relates to a data quality control method of an anchored buoy station, wherein the data of the anchored buoy station includes historical data, comparison data and model data, comprising the following steps: selecting an extremum corresponding to each meteorological element according to the historical data, Obtain the climatological limit value corresponding to each of the meteorological elements; correct the historical data according to the climatological limit value to obtain corrected data; respectively compare the comparison data and the corrected data with the The model data is verified to obtain a verification result; according to the verification result, it is judged whether the climatology threshold value is a positive correction to the historical data. In the technical scheme of the present invention, it can provide a strong guarantee for the construction and operation of my country's marine meteorological observation system, and combine scientific research with actual business needs, especially in the aspect of anchored buoy observation, filling the gap between anchored buoy observation Gaps in data quality control.

Description

technical field [0001] The invention relates to the field of data quality control, in particular to a data quality control method and system for an anchored buoy station. Background technique [0002] Due to the limitations of technical level and economic conditions, my country's marine meteorological observation started late and progressed slowly. After entering the 21st century, my country began to attach importance to the construction of marine observation systems, increased investment in technology research and development and construction, and the construction of marine observation systems entered a period of rapid development. At present, my country's marine meteorological observation has begun to take shape, and initially formed island stations, buoy stations, oil platform stations, ship stations, coastal meteorological observation towers, weather radars, wind profile radars, GNSS / MET water vapor observations, and meteorological satellites. Marine meteorological observa...
