With the rapid development of satellite remote sensing technology, carbon-cycle research,
as a key focus of global climate change, has also been widely developed in terms of carbon …

Abstract The Orbiting Carbon Observatory-3 (OCO-3) is NASA's next instrument dedicated to
extending the record of the dry-air mole fraction of column carbon dioxide (XCO 2) and solar …

The Orbiting Carbon Observatory-2 (OCO-2) carries and points a three-channel imaging
grating spectrometer designed to collect high-resolution, co-boresighted spectra of reflected …

Since September 2014, NASA's Orbiting Carbon Observatory-2 (OCO-2) satellite has been
taking measurements of reflected solar spectra and using them to infer atmospheric carbon …

NASA's Orbiting Carbon Observatory-2 (OCO-2) has been measuring carbon dioxide
column-averaged dry-air mole fraction, X CO 2, in the Earth's atmosphere for over 2 years. In …

The Orbiting Carbon Observatory 2 (OCO-2) satellite has been providing information to
estimate carbon dioxide (CO 2) fluxes at global and regional scales since 2014 through the …

The atmospheric concentration of methane has more than doubled since the start of the
Industrial Revolution. Methane is the second-most-abundant greenhouse gas created by …

INTRODUCTION Earth's carbon cycle involves large fluxes of carbon dioxide (CO2)
between the atmosphere, land biosphere, and oceans. Over the past several decades, net …

This work describes the NASA Atmospheric CO 2 Observations from Space (ACOS) X CO 2
retrieval algorithm, and its performance on highly realistic, simulated observations. These …

We evaluate the global atmospheric methane column retrievals from the new TROPOMI
satellite instrument and apply them to a global inversion of methane sources for 2019 at 2∘× …
