The BrokerGEO 1.3.9 release includes updates aligned to developments in the GEOSPACE-1D model, now available in version 1.2.9. It incorporates root density as an input parameter within the system. Significant improvements have been made to enhance the readability of the model. Furthermore, corrections have been implemented in the partitioning of evapotranspiration across each control volume. These modifications consider both water stress and root density, resulting in more accurate and realistic calculations.
