The China Meteorological Administration (CMA) has officially incorporated two groups of small commercial satellites into its weather observation system, marking a significant milestone as this is the administration's first use of data from such satellites for weather services.
On Dec. 30, the 23-satellite Tianmu-1 meteorological constellation and the 12-satellite Series began supplying data to the CMA. Preliminary trial results indicate that these satellite groups are enhancing the CMA's weather forecasting capabilities.
Currently, the Tianmu-1 constellation provides approximately 30,000 occultation profile products daily, while the Yunyao-1 satellites contribute around 15,000 profiles.
These occultation profile products are processed through the CMA's meteorological big data cloud platform, Tianqing, and are utilized across various operational modules, including observation and forecasting, numerical prediction, global typhoon monitoring, and short-term forecasting for severe weather phenomena like hail and lightning. They also aid in climate change research.
The Tianmu-1 is notable for being the first domestic satellite constellation compatible with major global navigation systems such as BeiDou and GPS. It offers high precision and vertical resolution without the need for calibration, providing comprehensive observational capabilities for marine, atmospheric, and ionospheric environments.
Fang Xiang, director of the CMA's integrated observation department, emphasized the crucial role that data from small commercial satellites can play in weather forecasting and the importance of promoting their development.
The operators of the Tianmu-1 and Yunyao-1 satellites are tasked with providing the CMA with satellite, payload, and product information, ensuring the timely transmission of satellite data products, and maintaining the stability and accuracy of the data received.
