No apparent relationship between GPP and NEP (in the same year, anyway)
Conclusions Inversions do manifest more seasonality, uptake, and IAV over N. America than forward models. Inversions don't agree as well as one might hope. MODIS GPP generally smaller than forward simulations. MODIS, CASA models and DLEM see less GPP in 2002, but NEE signal is not apparent.
