abstract = "Land surface/ecosystem models (LSEMs) play a key role in
understanding the Earths climate. They represent ecosystem
dynamics by simulating fluxes occurring between the biosphere and
atmosphere. However, for a correct flux simulation, it is critical
to calibrate the model using robust and state-of-the-art
calibration techniques. In this work, we optimize parameters of
the Integrated Model of Land Surface Processes (INLAND) using the
hierarchical multi-objective calibration method (AMALGAM) to
improve the representation of surface processes in a natural
ecosystem over the Pampa biome in South America. The calibration
was performed using experimental data of energy and CO2 flux
collected in a native field located in southern Brazil. We
compared simulations using the default and calibrated parameter
set. The results show that the calibration of the model
significantly improved all fluxes analyzed. The mean errors and
bias values were significantly reduced, and the seasonality of
fluxes was better represented. This work is one of the first to
apply a multi-objective calibration in an LSEM to represent
surface fluxes in the Pampa biome, presenting a consistent set of
parameters for future applications used in studies of biome land
use and land cover.",
