Enhanced Quantification of Global Carbon Emitters Using Collocated OCO‐3 CO2 and NO2 Observations From Twin Polar‐Orbiting Satellites

Geophysical Research Letters, Volume 52, Issue 16, 28 August 2025.
Abstract Satellite‐based estimates of fossil fuel carbon dioxide (FFCO2) emissions are crucial for global stocktaking but are limited by sparse coverage. As nitrogen dioxide (NO2) observations can enhance CO2 emission estimates, we use NO2 observations from twin polar‐orbiting satellites (GaoFen‐5B and DaQi‐1) to constrain carbon emission estimates ...

Comprehensive Analysis of Bias in TEMPO NO2 Column Densities Through Pandora Observations

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 15, 16 August 2025.
Abstract Tropospheric Emissions: Monitoring of Pollution (TEMPO) is the first geostationary satellite instrument to monitor air pollutants across North America. This study uses Pandora observations to analyze the bias in TEMPO Level‐3 total column density of NO2 (TOTNO2) from August 2023 to December 2024.
