Aerial Remote Sensing And Satellite Remote Sensing Systems
According to the latest news, China's aerial remote sensing system has successfully obtained the world's first effective multi-source remote sensing detection data of mountain glaciers. This achievement marks a major breakthrough in the field of remote sensing technology in the country and also provides strong support for global climate change research.
The experiment started on March 20 and ended in mid-May. It is an important part of China’s second comprehensive scientific investigation on the Qinghai-Tibet Plateau, and it is the first time in the world to carry out a P/L/VHF three-band radar joint glacier detection experiment based on an aviation platform.
The remote sensing aircraft used in the test is the domestic Xinzhou 60 remote sensing aircraft. Up to now, this experiment has accumulated 11 sorties, including 7 sorties of P/L band tomography and interferometric imaging, 4 sorties of VHF band perspective imaging, and obtained 4.6TB of effective data.
Mountain glaciers are one of the most important water resources on earth, and they are also one of the important indicators of global climate change. Due to the wide distribution, large area and rapid change of mountain glaciers, the monitoring and prediction of them have always been a research hotspot in the fields of meteorology and geography.
However, because mountain glaciers are limited by geophysical conditions, traditional observation methods often have limitations. Remote sensing technology can improve the monitoring accuracy and timeliness of mountain glaciers through the acquisition and analysis of multi-source data.
The world's first set of multi-source remote sensing effective detection data of mountain glaciers obtained by China's aerial remote sensing system this time is composed of data from multiple satellites, including optical satellites, microwave satellites and other types of satellite data.
Through the processing and analysis of these data, scientists obtained high-precision parameters such as mountain glacier coverage and ice volume and further explored their relationship with global climate change.
According to reports, the data has the following characteristics: first, it covers a wide range and can monitor mountain glaciers around the world; Timeliness; the third is good repeatability, the data can be used multiple times, and with the continuous advancement of technology, its monitoring effect will also continue to improve.
The release of this achievement not only marks a major breakthrough in the field of remote sensing technology in the country but also provides strong support for global climate change research. In the future, China will continue to strengthen the research and application of remote sensing technology to provide more accurate data for humans to better understand the earth's environment and respond to climate change.
