Innovative Ground-Based Infrared Hyperspectral Device Enhances Environmental Monitoring

Mar 19, 2024 | By GUO Qijing; ZHAO Weiwei

Recently, a team led by Prof. LI Dacheng from Hefei Institutes of Physical Science (HFIPS), Chinese Academy of Sciences (CAS), developed a high-spectral device capable of meeting high-precision continuous measurements–the Ground-based Infrared Hyperspectral Spectrometer. This device is designed to continuously and accurately assess the radiation characteristics of both the atmosphere and the Earth's surface, providing crucial data to better understand changes in our environment.

Understanding changes in the atmosphere is crucial for remote sensing and our comprehension of the Earth's systems. Accurate hyperspectral measurements are essential for acquiring atmospheric parameters and calibrating space-based sensors. They ensure the reliability of optical remote sensing data and enhance our understanding of the Earth-atmosphere system.

In this research, the team, along with their international partners, enhanced the environmental adaptability of hyperspectral equipment.

They improved the measurement accuracy of hyperspectral equipment under long-term unattended conditions to meet the requirements of hyperspectral observation in automatic observation of atmospheric and environmental characteristics.

At the same time, the improvement and adjustability of the spectral resolution of hyperspectral equipment provide better adaptability for the acquisition of spectral data information.
