mel v figure

MBL MEL V is a simplified, annual-time-step version of MBL MEL IV. It is easier to implement and less computationally intensive than the daily time-step version of the MEL model (version IV). MBL MEL V combines the separate ammonium and nitrate into dissolved inorganic nitrogen and the carbon and light resources into a single resource labeled carbon. It also replaces the water budget with a simple moisture index. Application of MBL MEL V to Hubbard Brook shows that it captures the long-term dynamics of the daily time-step model (MBL MEL IV) well.
