Measurement report: Quantifying the trade-off between station number and spatial layout in sparse GNSS networks for calibrating all-weather FY-4A precipitable water vapor

Abstract. Integrating satellite-derived precipitable water vapor (PWV) provides data with high spatiotemporal resolution, which is crucial for monitoring and forecasting extreme weather. However, current fusion and calibration methods typically relies on dense GNSS networks, hind...
