Imaging Spectroscopy for Earth and Planetary Science: Investigations, Future Missions, and Analysis Methods

Anticipated orbital imaging spectrometers promise a revolution in our understanding of terrestrial and aquatic ecosystems. These include the NASA EMIT Mission, to be launched in 2021 to the ISS, and a global Surface Biology and Geology investigation designated by the Earth Science Decadal Survey...

Understanding the Effects of Parameter Uncertainty in Water and Carbon Models

Models of ecosystems or water at the land surface represent a large number of uncertain processes. Over time, these models have become increasingly complex, capturing ever more processes. However, the model parameters in these process representations often vary dramatically in space but are...

Large Historical Growth in Global Terrestrial Gross Primary Production

Growth in terrestrial gross primary production (GPP)—the amount of carbon dioxide that is ‘fixed’ into organic material through the photosynthesis of land plants—may provide a negative feedback for climate change. It remains uncertain, however, to what extent biogeochemical processes can...
