Climatology-based regional modelling of potential vegetation and average annual long-term runoff for Mesoamerica
Climatology-based regional modelling potential vegetation long-term runoff Mesoamerica
2010/12/22
Mean annual cycles of runoff, evapotranspiration, leaf area index (LAI) and potential vegetation were modelled for Mesoamerica using the SVAT model MAPSS with different climatology datasets. We calibr...
