“The research team from Hunan University proposed a two-step method for high dynamic node parameterized water vapor chromatography, which reconstructs the linear trend term of the water vapor field over a long period of 30 minutes; The second step is to further invert the high-frequency deviation term within a 5-minute short period based on the modeling residuals from the first step, thereby achieving accurate reconstruction with high spatiotemporal resolution, providing a new tool for extreme weather warning.”
