Climate projections continue to be marred by large uncertainties, which originate in
processes that need to be parameterized, such as clouds, convection, and ecosystems. But …

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 …

The application of the eddy covariance flux method to measure fluxes of trace gas and
energy between ecosystems and the atmosphere has exploded over the past 25 years. This …

Despite its key role in climate change, large uncertainties persist in our knowledge of the
anthropogenic emissions of carbon dioxide (CO 2) and no global observing system exists …

Globally mapped terrestrial chlorophyll fluorescence retrievals are of high interest because
they can provide information on the functional status of vegetation including light-use …
