- China Meteorological Administration releases AI solar radiation forecasting model
China's Meteorological Administration has released an AI solar radiation forecasting model called Fengyuan Radiation Perception and Forecasting Model, according to a Xinhua report relayed by 36Kr. The report describes it as the country's first end-to-end AI solar radiation forecasting model driven by a fusion of geostationary satellite data and a ground-based minute-level radiation observation network, and says it enables real-time monitoring and ultra-short-term forecasting of ground solar radiation stations and grids nationwide. It is positioned as technical support for ultra-short-term photovoltaic power forecasting.
36氪快讯 · 🔥 0 - Tianxu Intelligent raises funding to put its weather AI model in orbit
Tianxu Intelligent Technology (Jiaxing) has closed a Pre-A+ round of tens of millions of yuan, solely funded by Houxue Capital, with proceeds going mainly to its Ningkong satellite constellation, energy-weather model updates, hiring and overseas research. The company says its self-developed vertical weather model, under 10 billion parameters, uses a "Lorentz framework" that adapts Transformer attention for wind-speed and irradiance forecasting, and claims its 1-km wind predictions beat EC-HRES and AIFS on RMSE and correlation metrics. It adds that its weather model reached orbit aboard a satellite on July 24, 2026 and passed daily validation, with a long-term plan for 18 satellites and two pilot satellites in 2027.
