Atmospheric water vapor content monitoring method, device, computer equipment and storage medium

Abstract

The application relates to a method, a device, a computer device and a storage medium for monitoring atmospheric water vapor content. The method includes: acquiring first atmospheric water vapor data and second atmospheric water vapor data within the time period to be measured in the target area; performing time reconstruction and / or spatial reconstruction on the second atmospheric water vapor data to obtain spatially complete second atmospheric water vapor data; Perform quality screening on the spatially complete second atmospheric water vapor data to obtain the target second atmospheric water vapor data; resample the first atmospheric water vapor data to obtain the target first atmospheric water vapor data; use the enhanced adaptive spatio-temporal fusion algorithm to generate fusion data, according to the fusion The data and the target second atmospheric water vapor data calculate the atmospheric water vapor content of the target area in the time period to be measured. This method obtains time-space continuous fusion products by fusing high-resolution and low-resolution atmospheric data, which can display the spatial details of atmospheric water vapor changes and has high product accuracy.

Description

technical field [0001] The present application relates to the field of satellite remote sensing technology, in particular to a method, device, computer equipment and storage medium for monitoring atmospheric water vapor content. Background technique [0002] Atmospheric water vapor content, also known as Precipitable Water Vapor (PWV), is one of the most active atmospheric variables affecting atmospheric circulation patterns and regional water balance. Atmospheric water vapor content is closely related to hydrological processes such as precipitation and evapotranspiration. The monitoring of water vapor content is of great significance to the study of water cycle characteristics.

Problems solved by technology

[0003] Existing atmospheric water vapor products include a variety of products, such as the global atmospheric reanalysis data set ERA-Interim provided by the European Center for Medium-Range Weather Forecasts (ECMWF). The product has a low spatial resolution and cannot display the spatial details of atmospheric water vapor changes; another example is the Moderate Resolution Imaging Spectrometer (MODIS) carried by NASA's Terra satellite, which can provide global atmospheric precipitable water MOD05 Product, the spatial resolution of this product is high, but due to the influence of satellite orbit, the space of this product is not continuous when monitoring atmospheric water vapor content; and this product is greatly affected by cloud cover, resulting in low data accuracy, which largely limits The Application Value of High Resolution Remote Sensing Data in Monitoring Atmospheric Water Vapor Content
