Airborne remote sense mapping of a dairy trace gas plume for over 20 km. In situ identification of far-field (70-km) downwind plume by surface in situ and satellite. Good herd size agreement for a dairy and the Chino Dairy Complex based on multiple gas emissions estimates. NH3 lifetime was rapid, ∼6 h, likely due to increased oxidation from the higher oxidant loads in Los Angeles. IASI satellite NH3 and CH4 confirmed downwind plume and transport patterns identified in airborne imaging spectroscopy and surface in situ data.
