BROOK90 is a hydrological model that simulates vertical soil water movement and daily evapotranspiration for all land surfaces at all times of year using a process-oriented approach with physically-meaningful parameters. The complexities of hillslope hydrology and spatial distribution have been omitted in order to focus on the details of the factors controlling evaporation. The model estimates interception and transpiration from a single layer (big leaf) plant canopy, soil and snow evaporation, snow accumulation and melt, and soil-water movement through one or more soil layers (including macropore-assisted infiltration).

Ecosystem Demography model (ED2)

ED2 is an integrated terrestrial biosphere model incorporating hydrology, land-surface biophysics, vegetation dynamics, and soil carbon and nitrogen biogeochemistry. Like ED, ED2 uses a set of size- and age-structured partial differential equations that track the changing structure and composition of the plant canopy.

FORest Canopy Atmosphere Transfer (FORCAsT)

FORest Canopy Atmosphere Transfer model is a canopy model capable of simulating the formation of secondary organic aerosol (SOA) from biogenic VOC oxidation.

Functionally Assembled Terrestrial Ecosystem Simulator (FATES)

FATES is a terrestrial ecosystem model that simulates and predicts growth, death and regeneration of plants and subsequent tree size distributions. When coupled into an earth system model, FATES allows representing potential ecosystem responses to environmental resource variability (water, light, nutrients), climate and atmospheric compositional changes.

Joint UK Land Environment Simulator (JULES)

JULES is a community land surface model that is used both as a standalone model and as the land surface component in UK’s Met Office Unified Model. JULES has a tiled model of sub-grid heterogeneity with separate surface temperatures, short-wave and long-wave radiative fluxes, sensible and latent heat fluxes, ground heat fluxes, canopy moisture contents, snow masses and snow melt rates computed for each surface type in a grid-box.


MILLENIAL is a soil model developed to simulate C pools that can be measured by extraction or fractionation, including particulate organic C, mineral-associated organic C, aggregate C, microbial biomass, and low molecular weight C. Model processes have been updated to reflect the current understanding of mineral-association, temperature sensitivity and reaction kinetics.

The Canadian Land Surface Scheme Including Biogeochemical Cycles (CLASSIC)

CLASSIC is a land surface model that simulates the exchanges of energy, water, carbon, and momentum at the earth’s surface. CLASSIC is formed by the coupling of the Canadian Land Surface Scheme (CLASS) and the Canadian Terrestrial Ecosystem Model (CTEM). CLASS handles the model physics including fluxes of energy, water and momentum. CTEM simulates biogeochemical cycles including fluxes of carbon.

University of Virginia Forest Model Enhanced (UVAFME)

UVAFME is an individual-based gap model that simulates the annual establishment, growth, and mortality of individual trees on independent patches (i.e. plots) of a forested landscape. The model is only spatially distributed in the vertical dimension, and plots are assumed to have no direct spatial interactions with one another. Through a Monte Carlo-style aggregation, the average of several hundred of these independent patches represents the average expected conditions of a forested landscape through time.
