Abstract The 2015 Paris Agreement of the United Nations Framework Convention on
Climate Change aims to keep global average temperature increases well below 2° C of …

The atmospheric concentration of methane has more than doubled since the start of the
Industrial Revolution. Methane is the second-most-abundant greenhouse gas created by …

Background Livestock play an important role in carbon cycling through consumption of
biomass and emissions of methane. Recent research suggests that existing bottom-up …

Greenhouse gas emissions from meat and dairy production are often highly uncertain; these
emissions are typically estimated using inventory-based,'bottom-up'models, which contain …

Reported estimates of CH 4 emissions from ruminants and manure management are up to 2
times higher in atmospheric top-down calculations than in bottom-up (BU) inventories. We …

State inventories indicate that dairy operations account for nearly half of California's
methane budget. Recent analyses suggest, however, that these emissions may be …

We combine sustained observations from a network of atmospheric monitoring stations with
inverse modeling to uniquely obtain spatiotemporal (3‐km, 4‐day) estimates of methane …

Dairies emit roughly half of total methane (CH 4) emissions in California, generating CH 4
from both enteric fermentation by ruminant gut microbes and anaerobic decomposition of …

We quantify 2019 methane emissions in the contiguous US (CONUS) at 0.25°× 0.3125°
resolution by inverse analysis of atmospheric methane columns measured by the …

This study derives methane emission rates from 92 airborne observations collected over 23
facilities including 5 refineries, 10 landfills, 4 wastewater treatment plants (POTWs), 2 …
