Flux Towers: Part II

Flux tower eddy covariance instruments measure CO2 flux between an ecosystem and the atmosphere. Observed CO2 fluxes (also called NEE, Net Ecosystem Exchange) can be correlated with locally measured solar…

Flux Towers: Part I

Most solar energy absorbed at the earth’s surface is radiated back into space. For every high energy solar photon absorbed, about 20 degraded thermal photons are eventually radiated back. Ecosystems…
