Optimization of ecosystem model parameters using spatio-temporal soil moisture information
L Zhu, JM Chen, Q Qin, J Li, L Wang - Ecological modelling, 2009 - Elsevier
Parameters in process-based terrestrial ecosystem models are often nonlinearly related to
the water flux to the atmosphere, and they also change temporally and spatially. Therefore,
for estimating soil moisture, process-based terrestrial ecosystem models inevitably need to
specify spatially and temporally variant model parameters. This study presents a two-stage
data assimilation scheme (TSDA) to spatially and temporally optimize some key parameters
of an ecosystem model which are closely related to soil moisture. At the first stage, a …
