DALEC2 is an intermediate complexity model of terrestrial carbon cycling. DALEC2 ("Data assimilation linked ecosystem carbon model, version 2") resolves gross primary production; its allocation to labile, foliar, wood and fine root pools; the turnover and mortality of these pools, generating dead organic matter; the mineralisation of dead organic matter in litter and soil. DALEC2 operates at daily-monthly timescales, and requires as input daily max and min temperature, total daily shortwave radiation, atmospheric CO2 concentration and day of year. DALEC2 has 6 C pools, 17 fluxes, and 17 parameters. The GPP model is ACM, a sub-model that has 10 parameters - 9 of these are fixed, and one is a common parameter with DALEC2.
