  • Performance of a dispersion model to estimate methane loss from cattle in pens

    Received for publication December 29, 2008. Accurate measurements of enteric methane (CH4) emissions from cattle (Bos taurus) are necessary to improve emission coefficients used in national emissions inventories, and to evaluate mitigation strategies.
