The ocean covers 70% of the Earth's surface and is the largest natural ecosystem on Earth. Due to the complex and ever-changing marine environment, environmental monitoring and emergency early warning are crucial. Among these, the monitoring and forecasting of marine hydrological information using satellite remote sensing technology is vital for the development of marine resources, the growth of the marine economy, the protection of marine ecosystems, and the safeguarding of maritime rights.

Snow cover is a significant winter climate phenomenon in my country, impacting climate change, water resources, the ecological environment, and animal husbandry. However, due to my country's vast and complex topography, traditional accurate monitoring methods are limited by factors such as a small number of observation stations, uneven spatial distribution, discontinuous observation time, and insufficient information on regional snow cover distribution and changes. Today, with continuous technological advancements, satellite remote sensing has become an ideal tool for snow cover monitoring. Snow cover monitoring methods based on satellite remote sensing technology can accurately and efficiently obtain snow cover information for various regions, providing crucial support for my country's ecological environment management and animal husbandry development.

On September 23, 2023, a delegation of nine people, led by Kong Shuguang, Secretary of the Party Leadership Group and Director of the Xiamen Municipal Science and Technology Bureau, and Cao Weimin, Member of the Party Leadership Group and Deputy Director of the Xiamen Municipal Science and Technology Bureau, visited Xi'an Xi'an Institute of Optics and Precision Mechanics CAS Aerospace Science and Technology Group Co.,LTD Technology Co., Ltd. for inspection and guidance.

Wetlands possess vital ecological functions, including regulating climate, maintaining biodiversity, purifying water, and regulating floods, and are an important component of the global carbon cycle. Over the past century, under the dual pressures of climate change and human activities, the global wetland area has drastically decreased, with ecosystem structures being damaged, functions declining, and even lost. In particular, the spatial extent of wetlands in China has shrunk significantly. Ensuring the sustainable development of wetland environments and resources has become a critical issue.
