Summary: This study presents the first estimates of global carbon surface fluxes inferred from satellite XCO2 measurements by the Chinese TanSat satellite. Results indicate that assimilating satellite XCO2 measurements provides highly effective constraints on global carbon flux estimation, with significant spatiotemporal shifts in flux patterns observed in critical regions. The integrated global land carbon net flux estimated from TanSat XCO2 data is generally consistent with other satellite data inversions, highlighting the potential for further studies using TanSat XCO2 data in conjunction with other measurements to quantify biosphere-atmosphere carbon exchange.

Summary: TanSat is the third satellite for global CO2 monitoring, capable of detecting weak solar-induced chlorophyll fluorescence signals and successfully retrieving global SIF products using a physically based algorithm from March 2017 to February 2018. Comparative analysis shows regional biases between the IAPCAS TanSat SIF product and the data-driven SVD SIF product, with linear correlations above 0.73 for all seasons.

Summary: This study compares the differences in CO2 data between satellites from Japan, USA, and China with the data from the Total Carbon Column Observing Network (TCCON). The findings reveal variations in CO2 concentrations among satellites in different seasons and latitudes, but there is a strong correlation with ground-based observations.

Summary: This paper introduces a new TanSat global XCO2 product developed by IAPCAS, with improved accuracy and precision through spectrum correction. The results show good agreement when compared with the UoL-FP retrieval algorithm, indicating potential for further application in global carbon flux studies.

Summary: This paper introduces the first attempt to detect anthropogenic CO2 emission signatures using data from China's TanSat satellite and the TROPOMI instrument on board the Copernicus Sentinel-5 Precursor satellite. The results show that TanSat's CO2 measurements have the capability to capture anthropogenic variations and have similar spatial patterns with TROPOMI's NO2 observations.

Summary: This paper focuses on the biochar synthesized from different parts of the Al Ghaf tree to determine their carbon dioxide capture abilities. The results show that biochar derived from the leaves of the Al Ghaf tree achieves the highest carbon dioxide capture capacity.

Summary: This study uses the TanSat satellite data to estimate global and regional terrestrial net ecosystem exchange (NEE). The results show an increase in global carbon uptake compared to previous estimates, with a decrease in carbon uptake in northern regions and an increase in carbon release in tropical and southern lands. However, the study also points out that there are biases in the TanSat observations in the northern high latitudes and northern Africa, which need to be addressed for better accuracy in estimates.

Summary: Global forests have been a net carbon sink over the past two decades, with an estimated annual net carbon uptake ranging from -7.6 +/- 49 GtCO(2)e. The study integrates ground and Earth observation data to map forest-related greenhouse gas emissions and removals globally, aiming to support the development of climate policies. This geospatial monitoring framework introduced in the research aims to promote consistency and transparency in climate policy development.

Summary: This study assessed the net Delta AGB derived from four global multi-date AGB maps over the past decade. The comparison between LiDAR data and maps showed reasonable agreement, while the comparisons using NFI only had some agreements at smaller aggregation levels. Disagreement between maps is still large in key forest regions. The results suggest that the AGB assessed from current maps can be biased and any use of the estimates should consider this.

Summary: A substantial amount of CO2 is released from the high-temperature decomposition of limestone to produce lime. However, the alkaline components of lime continuously absorb CO2 during use and waste disposal. Our study provides regional and global estimates of carbon uptake from lime production and supports including lime carbon uptake into global carbon budgets.

Summary: The defossilisation of the global energy system is a key goal to mitigate climate change. This research analyzes the global demand for carbon dioxide as raw material for the production of renewable electricity-based fuels and chemicals during a global energy transition to 100% renewable energy. It evaluates the carbon dioxide capture and utilisation potentials from key industrial point sources. The study estimates that the demand for carbon dioxide will increase from 0.6 gigatonnes in 2030 to 6.1 gigatonnes in 2050, with key industrial point sources potentially supplying the majority of the demand in the 2030s and direct air capture supplying the majority by 2050.

Summary: Although light-driven conversion of carbon dioxide receives widespread attention, the challenge of distinguishing true product formation from impurities has been a criticism. However, advanced guidelines for proper product identification have been developed, allowing for greater trust in the observed outcomes.
