Measuring and Managing Emissions from Cattle in Australia’s Northern Rangelands: Utilising Open-Path Optical Techniques.

Not Accessible

Your library or personal account may give you access

Abstract

Agriculture contributes around 11% of Australia’s greenhouse gas budget, with approx. 90% from ruminants. Open-path optical techniques offer an opportunity to measure the methane mole-fraction downwind from livestock to derive herd-averaged emissions.
