Coastal wetland GHG model (CWGM) overview
3
The coastal wetland GHG model (CWGM) is a power-law based empirical model developed by using data for four different wetlands in Waquoit Bay and adjacent estuaries, MA, representing biogeochemical and ecological gradients. The model predicts daytime net uptake fluxes of CO2 (NEECO2,uptake, units: µmol/m2/s), nighttime emission fluxes of CO2 (NEECO2,emission, units: µmol/m2/s), and net emission fluxes of CH4 (NEECH4,emission, units: nmol/m2/s) from photosynthetically active radiation (PAR, units: µmol/m2/s), soil temperature (ST, units: °C), and porewater salinity (SS, units: parts per thousand, ppt). A robust multivariate data analytics framework was utilized to select the dominant environmental drivers of fluxes as model inputs. The model is simple, handy and user-friendly, and only requires a single set of input variables to predict the GHG fluxes.
