CO emissions and NO x /CO ratios from the extreme 2025 Iberian wildfires: TROPOMI-based estimates and comparison with inventories

Satellite-Based Clustering of Pre-Monsoon Wildfires and Variability of 1 Tropospheric NO₂ and CO in Nepal

Quantifying CO and NO₂ transport fluxes over southeastern Australia: implications from the 2019-2020 Black Summer and multi-year variability

The 2019–2020 Black Summer (BS) wildfires provide a representative case for quantifying how extreme biomass burning affects regional pollutant transport. In this study, we combine satellite-derived column concentrations, ground-based observations, flux diagnostics, and forward trajectory analysis to evaluate the cros...

Understanding the sources and variability of methane emissions in Madrid with Sentinel-5P TROPOMI, GHGSat, and aircraft observations

Tower- and drone-based BVOC observations in a suburban Tokyo forest: methodological insights and MEGAN comparison

Abstract. Biogenic volatile organic compounds (BVOCs) substantially influence regional photochemical air pollution, climate, and the carbon cycle. However, observational constraints on BVOC emissions from urban or suburban forests in Asian megacity regions under humid subtropical climates remain limited. In this study,...

Evaluating In Situ and OCO-3 CO2 Observations in the Sichuan Basin Using WRF-Chem Simulations and Footprint Analysis

Revealing the spatiotemporal patterns and controlling factors of atmospheric CO2 in the Sichuan Basin (SCB) is a prerequisite for the scientific regulation of regional carbon sources and sinks. This study investigates surface and column-averaged CO2 concentrations in SCB and surrounding regions during August to Decembe...

Evidence for the impact of fire activity on daily variations of IASI mid-tropospheric CO 2 anomalies at 8–11 km over South America: a pyroconvective fingerprint
