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
无人机在摄影、检查和交付方面变得非常有用。 They are highly maneuverable and can hover in one place, but they have a major weakness: they use a lot of energy. Their spinning propellers need a constant supply of power, which limits how long they can stay in the air.飞机则相反[…]科学家建造的受鸟类启发的机器人,可以在没有螺旋桨的情况下随风漂浮,这篇文章首先出现在《Knowri
