Core Viewpoint - The successful launch of the Fengyun-4C satellite enhances China's meteorological satellite capabilities, contributing to a robust network of over 20 Fengyun satellites, which are crucial for weather forecasting and disaster prevention [2][6]. Group 1: Satellite Capabilities - Fengyun-4C satellite is equipped with four different ground remote sensing instruments and two solar observation instruments, showcasing advanced capabilities in multi-channel imaging, atmospheric three-dimensional detection, and high-frequency lightning detection [2][5]. - The advanced geostationary radiation imager can now achieve full-disk imaging in 5 minutes, improving the detection of atmospheric temperature changes to one-fiftieth of a degree Celsius [3]. - The interferometric infrared detector has improved spatial resolution from 12 kilometers to 8 kilometers, allowing for temperature and humidity detection across China within one hour [3]. Group 2: Technological Innovations - Fengyun-4C introduces several innovative technologies that fill domestic and international gaps, including a high-spectral ionospheric detection capability in the extreme ultraviolet band [4][5]. - The lightning imaging instrument can capture 500 frames per second and identify lightning events from a data stream of 30 Gbps, demonstrating significant advancements in data processing and observation [5]. Group 3: Collaborative Observation Network - The addition of Fengyun-4C supports inter-satellite collaboration and high-speed data transmission, enhancing the overall observational network for weather forecasting, disaster prevention, and ecological monitoring [6]. - The integration of multiple geostationary and low-orbit meteorological satellites aims to create a "data highway" in space, moving towards the goal of immediate observation and service [6].
