Atmospheric chemistryTwo hotspots at a Korean petrochemical complex emit about 37.1 % of its reported total
Measurements from the ground, a vehicle, an aircraft and a satellite suggest that two facilities in the Daesan petrochemical complex emit about 37.1 % of the whole complex's inventory total, which points to underreported methane leaks.

Atmospheric chemistrySatellite data show a data center power plant emitting about 16 times its permitted NOx
NASA's TEMPO satellite detected nitrogen oxide emissions from the Colossus 2 gas turbine plant that averaged 730±185 kg h-1 after February 2026, roughly 16 times the permit-based expectation of about 47 kg h-1.

Atmospheric chemistryLow-producing US well-pads emit over half of well-pad methane but make 5% of output
In this preprint, satellite data suggest that US oil and gas well-pads producing under 15 boe per day account for 5% of production but over half of well-pad methane emissions.

Atmospheric chemistryNew global methane inventory for oil, gas and coal totals 74 Tg a−1 in 2020
GFEI v3 maps nationally reported 2020 fossil fuel methane emissions onto a 0.1° grid using new infrastructure and coal mine data, and it stays below other inventories and satellite-based estimates.
-
Atmospheric chemistryAGAGE data show 2023 emissions and levels of 42 trace gases, with limits
Using AGAGE station measurements and a simple 12-box atmosphere model, the authors publish yearly global emissions and abundances for 42 trace gases through 2023, and explain how they are derived and where they fall short.

Atmospheric chemistryA global air pollutant emission mosaic now covers 2000–2020 at monthly resolution
HTAP_v3.2 blends official regional emission inventories with the EDGAR global inventory into one monthly, gridded dataset for nine air pollutants over 2000–2020.
