Since the mid-1990s a new generation of Earth-observing satellites has been able to detect
tropospheric air pollution at increasingly high spatial and temporal resolution. Most primary …

Good-quality CO 2 emission data are fundamental for effective climate policy and
governance. Data manipulation should be deterred, while develo** countries are …

Increasing our understanding of regional greenhouse gas transport, sources, and sinks
requires accurate, precise, continuous measurements of small gas enhancements over long …

In recent years, China has been experiencing increasing carbon dioxide (CO 2)
concentration. Spaceborne satellites provide important support to monitor CO 2, but the …

Carbonyl sulfide (COS) is an atmospheric trace gas that participates in some key reactions
of the carbon cycle and thus holds great promise for studies of carbon cycle processes …

Increases in atmospheric carbon dioxide (CO2) concentrations is the main driver of global
warming due to fossil fuel combustion. Satellite observations provide continuous global CO2 …

Dual-comb spectroscopy (DCS) provides broadband, high-resolution, high-sensitivity
amplitude and phase spectra within a short measurement time, thus holding promises for …

Argo floats measure seawater temperature and salinity in the upper 2000 m of the global
ocean. Statistical analysis of the resulting spatio-temporal dataset is challenging owing to its …

Fossil-fuel CO 2 emissions and their trends in eight US megacities during 2006–2017 are
inferred by combining satellite-derived NO X emissions with bottom-up city-specific NO X-to …

Column-averaged dry air mole fraction of atmospheric CO2 (XCO2), obtained by multiple
satellite observations since 2003 such as ENVISAT/SCIAMACHY, GOSAT, and OCO-2 …
