We built China's first ten-year record from a ground-based microwave sensor that tracks temperature and humidity above Xianghe. After checking data quality and separating clear, cloudy, and rainy periods, we produced reliable one- to ten-minute data for 2013-2022. Improved methods reduced errors in temperature and humidity estimates. The record shows that winter cold air is often trapped near the ground, especially during heavy fine-particle pollution, supporting weather and air-quality studies.
