This study evaluates the potential use of the ECMWF System‐4 seasonal forecasts ( S4 ) for impact analysis over East Africa. For use, these forecasts should have skill and small biases. We used the 15‐member ensemble of 7‐month forecasts initiated every month, and tested forecast skill of precipitation ( tp ), near‐surface air temperature ( tas ) and surface downwelling shortwave radiation ( rsds ). We validated the 30‐year (1...

Terrestrial gross primary production (GPP) is an important parameter to explore and quantify carbon fixation by plant ecosystems at various scales. Remote sensing (RS) offers a unique possibility to investigate GPP in a spatially explicit fashion; however, budgeting of terrestrial carbon cycles based on this approach still remains uncertain. To improve calculations, spatio‐temporal variability of GPP must be investigated in mo...
