The model simulated a reasonable annual net primary production (NPP) for Sphagnum gross primary production (GPP) albeit with an underestimate of peak GPP. Processes in ELM allows it to capture the observed seasonal dynamics of The inclusion of a Sphagnum PFT with some Sphagnum-specific The model was parameterizedĪnd independently evaluated against observations from an ombrotrophicįorested bog as part of the Spruce and Peatland Responses Under ChangingĮnvironments (SPRUCE) project. Nonvascular photosynthetic processes for moss.

Introduce a moss PFT into the land model component (ELM) of the EnergyĮxascale Earth System Model (E3SM) by developing water content dynamics and

Represented plant functional types (PFTs), thereby limiting predictiveĪssessment of peatland responses to environmental change. However, most land-surface models do not include Sphagnum or other mosses as Sphagnum mosses are strongĭeterminants of nutrient, carbon, and water cycling in peatland ecosystems. Peatland functional dynamics under the changing environment. Mosses need to be incorporated into Earth system models to better simulate
