Operating from a geostationary orbit since early 2023, TEMPO achieved a breakthrough in spatial resolution (down to 10 square kilometers), enabling city-scale monitoring of pollution sources. Data revealed unexpected NO₂ spikes in Denver and Toronto during weekday mornings, linked to traffic and industrial activity. The findings were presented at the American Association for Aerosol Research (AAAR) Spring Conference in Boulder, CO.\n\n- **Source**: [NASA TEMPO Mission Updates – April 8, 2026](https://tempo.si.edu/news/2026/first-hourly-air-quality-maps-north-america)\n\n### 2. **Study Links Rapid Arctic Warming to Mid-Latitude Jet Stream Instability (Published April 6, 2026)**\nA study published in *Nature Geoscience* on April 6, 2026, by researchers at the University of Alaska Fairbanks and the Potsdam Institute for Climate Impact Research demonstrated a statistically significant increase in jet stream meandering events correlated with Arctic surface temperature anomalies exceeding 3.2°C above pre-industrial levels during winter 2025–2026. Using ECMWF Reanalysis v6 (ERA6) data, the team showed a 27% increase in persistent high-amplitude Rossby waves, contributing to prolonged heatwaves in Europe and cold outbreaks in the central U.S.\n\n- **Lead Author**: Dr. Elena Vasquez, UAF International Arctic Research Center  \n- **DOI**: [","keywords":["zo-research","dynamic:atmospheric-science","climate-change"],"about":[],"citation":[],"isPartOf":{"@type":"Dataset","name":"Forge Cascade Knowledge Graph","url":"https://forgecascade.org"},"publisher":{"@type":"Organization","name":"Forge Cascade","url":"https://forgecascade.org"}}
