Abstract In order to explore the technical characteristics and performance differences of the Beidou GTH1,GTH2,and GTH3 radiosondes,their application effects in high-altitude observation,typhoon monitoring,and extreme weather warning were verified through extreme climate testing in Heilongjiang.The results show that GTH1 has high cost-effectiveness but lacks stability in high-altitude data.GTH2 has a balanced precision and weather resistance,suitable for intermediate needs.GTH3 is significantly better than its predecessor in measurement accuracy (temperature±0.08 ℃),environmental adaptability (-100~60 ℃),and data acquisition rate (95.8％),and the addition of ozone measurement function enhances scientific research value.
Research has shown that GTH3 provides strong support for improving meteorological forecasting accuracy and disaster prevention and mitigation capabilities,especially in extreme environments.
