GEDI data will help further refine our understanding of the carbon cycle and atmospheric concentrations of carbon dioxide (CO2).
Level 1 and 2 high-resolution, laser altimetry data from the Global Ecosystem Dynamics Investigation (GEDI) are now available from the LP DAAC.

Simulated and observed seasonal patterns of canopy SIF (740 nm) for (a, c) absolute SIF and (b, d) normalized canopy SIF for CLM simulation year 2010. Both a satellite SIF product (GOME-2) and the PhotoSpec measurements are included for comparison.
Three related datasets from the Carbon Monitoring System (CMS) program describe year-round photosynthetic activity in a conifer forest.

Upward-facing photo of the canopy at Harvard Forest (transect 2, plot 57) on 2012-10-18.
Ground-based data collected at the Harvard Forest site was used to validate Airborne Microwave Observatory of Subcanopy and Subsurface (AirMOSS) soil moisture estimates.

Predicted spatially contiguous solar-induced chlorophyll fluorescence (SIF) across the United States for August 1 - 16, 2015. Areas of high SIF are in red, and areas of low SIF are in blue. Agricultural areas, like the U.S. Midwestern corn belt, often have a high rate of photosynthetic production which results in high SIF.
High-resolution, global, estimates of SIF based on data from the OCO-2 satellite serve as a proxy for rates of terrestrial photosynthesis.
