Commonly Used NRCS Tools - COMET-Farm

Development History

COMET-Farm, and earlier versions of COMET, was developed through a partnership between NRCS and Colorado State University. There is more than a decade of model development experience reflected in COMET. COMET is the official greenhouse gas quantification tool of USDA.

Algorithm Overview

Details of the algorithm: COMET-Farm uses information on management practices on an operation together with spatially-explicit information on climate and soil conditions from USDA databases (which are provided automatically in the tool) to run a series of models that evaluate sources of greenhouse gas emissions and carbon sequestration. By integrating NRCS SSURGO database and site-specific climate data, locality-specific results are presented to COMET-Farm users. There are several modules nested within the model (i.e. Croplands, Livestock, Agroforestry, Energy), and the model relies on biogeochemical process models, IPCC methodologies, and a number of peer reviewed research results.
