A carbon-monitoring strategy through near-real–time data and space technology

Seasonal and Diurnal Variations in XCO2 Characteristics in China as Observed by OCO‐2/3 Satellites: Effects of Land Cover and Local Meteorology

“…Recently, several carbon‐monitoring satellites offering notable advantages in terms of spatial coverage and repeatable observations have been launched to collect data on global atmospheric CO 2 concentrations (Sellers et al., 2018). For example, the Scanning Imaging Absorption Spectrometer for Atmospheric Chartography (Buchwitz et al., 2007), Greenhouse Gases Observing Satellite (GOSAT) (Yokota et al., 2009), GOSAT‐2 (Suto et al., 2021), Orbiting Carbon Observatory (OCO)‐2 (Crisp et al., 2017), OCO‐3 (Eldering et al., 2019), and the Chinese CO 2 observation satellite (TanSat) (Y. Liu et al., 2018), have been in operation in space successively, thereby filling the gap in ground‐based observations and becoming the primary instrumental tool for determining XCO 2 information and enhancing awareness of global carbon processes under the feedbacks of climate change (Eldering et al., 2017; Z. Liu et al., 2023; Xiao et al., 2021).…”

Carbon Monitor Europe near-real-time daily CO2 emissions for 27 EU countries and the United Kingdom

“…Further, the private company Kayrros released a daily estimate of emissions from regulated sectors (European Trading Scheme) in November 2021 using site-level satellite monitoring of industrial activity, called Carbon Watch 20 . The Carbon Monitor international research initiative developed a new near-real-time daily dataset of CO 2 emissions with global coverage and country-level estimates for 12 countries which lags reality by only one month 1,3,[21][22][23][24][25][26] . Building on this foundation, they have also developed the Carbon Monitor China 27 , which provides provincial-level near-real-time daily emissions data for China, and the Carbon Monitor United States 28 , which provides state-level daily emissions data for the US.…”
