A Satellite-Based Global Carbon Flux Product is Sensitive to Droughts
A parsimonious ecosystem model constrained by data from NASA’s Soil Moisture Active and Passive mission generates a global daily carbon flux product that is highly sensitive to drought and pluvial events.
Scientists build bird-inspired robot that floats on wind without propellers
