COMET is the official greenhouse gas quantification tool of USDA. COMET-Farm, and earlier versions of COMET, was developed through a partnership between NRCS and Colorado State University. 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.
