TL;DR: The FLUXNET project as mentioned in this paper is a global network of micrometeorological flux measurement sites that measure the exchanges of carbon dioxide, water vapor, and energy between the biosphere and atmosphere.

TL;DR: For cities across North America, geographic variations in daytime ΔT are largely explained by variations in the efficiency with which urban and rural areas convect heat to the lower atmosphere, if urban areas are aerodynamically smoother than surrounding rural areas, urban heat dissipation is relatively less efficient and urban warming occurs (and vice versa).

TL;DR: In this article, the authors extend the discussions of a US DOE sponsored workshop held on 30 and 31 May, 2000 in Boulder, CO concerning issues and uncertainties related to long-term eddy covariance measurements of carbon and energy exchanges.

TL;DR: In this article, the WPL terms and spectral attenuation were revisited for the measurement of atmospheric trace gas fluxes with open-and closed-path eddy covariance system.

TL;DR: In this paper, it is shown from the mass conservation and the continuity equations that the net ecosystem exchange (NEE) of a scalar constituent with the atmosphere should be NEE =∫ z r 0 ∂ c ∂t d z+( w′c′ ) r + w r c r − 1 z r ∫ zr 0 c d z where the first term on RHS is the storage below the height of observation (zr), the second term is the eddy flux, and the third term is a mass flow component arising from horizontal flow convergence
