Carbon dioxide exchange above a Mediterranean C3/C4 grassland during two climatologically contrasting years

Eddy-covariance measurements of net ecosystem carbon exchange (NEE) were carried out above a grazed Mediterranean C3/C4 grassland in southern Portugal, during two hydrological years, 2004-2005 and 2005-2006, of contrasting rainfall. Here, we examine the seasonal and interannual variation in NEE and...
