The numerical weather model (NWM) is a commonly used data source in space geodesy and meteorology. Calculating meteorological parameters and atmospheric delay information at the target location using NWM products is a repetitive and challenging task that practitioners often encounter. To reduce the difficulty of using NWM and improve research efficiency, the Collaborative Precise Positioning Research Group has developed a site product module based on NWM. This module allows users to customize and generate products tailored to their needs, including meteorological parameters, zenith delays, mapping functions, and horizontal gradients
