BEIJING, July 26 (Xinhua) -- The following is a summary of published science and technology news of China.
SATELLITES FOR CLIMATE, CARBON MONITORING
China's atmospheric environment monitoring satellite and terrestrial ecosystem carbon monitoring satellite have been officially put into operation, the China National Space Administration (CNSA) said on Thursday.
During their in-orbit testing, these satellites demonstrated favorable application results across multiple areas, including ecological environment, forestry and grassland, geographic surveying, meteorology, agriculture and emergency disaster response, according to an official of the CNSA.
The two satellites will provide crucial data to effectively address global climate change and support China's goals of achieving carbon peak and carbon neutrality.
CARBON CAPTURE FACILITY
CarbonBox, China's independently developed direct air capture (DAC) facility, has passed its reliability verification, with a single module capable of capturing over 100 tonnes of carbon dioxide (CO2) directly from the air each year and generating 99 percent high-concentration product.
CarbonBox, developed by researchers at Shanghai Jiao Tong University (SJTU) and China Energy Engineering Corporation, has an annual CO2 capture capacity of 600 tonnes, marking a significant breakthrough in the country's DAC technology.
RAINFALL VARIABILITY
A new study has provided evidence showing that human activities have made global rainfall more volatile over the past century.
Published on Friday in the journal Science, the study was conducted by researchers from the Institute of Atmospheric Physics (IAP) of the Chinese Academy of Sciences, the University of Chinese Academy of Sciences, and the UK Met Office.
The study reveals a systematic increase in rainfall variability since the 1900s, ranging from global to regional scales and from daily to intraseasonal timescales. ■
