Aura's Ozone Monitoring Instrument (OMI) used in evaluating the reduction of nitrogen dioxide tropospheric vertical column densities before and after the Lunar New Year.
As a consequence of the nationwide stay-at-home order, less fossil fuels are being consumed and, subsequently, less air pollution is being emitted in India and also in neighboring countries, including Pakistan, Nepal, Bangladesh, and Sri Lanka.
The NASA standard nitrogen dioxide version 4.0 product for Aura's Ozone Monitoring Instrument (OMI) incorporates the most salient improvements and enhances the data quality.
What do long-term observations of ozone profiles from the Microwave Limb Sounder (MLS) aboard the Aura satellite tell us about the drivers of O3 variations near 90 km altitude (the secondary ozone maximum region), notably in relation to the 11-year solar cycle?
Aura Microwave Limb Sounder (MLS) measurements have previously shown that the easterly phase of the QBO is associated with increases in nitrogen in the Antarctic stratosphere.
Aura's MLS observes patterns of stratospheric humidity in the “Tropical Tropopause Layer” .
Aura's MLS observations of Arctic vortex-average chlorine monoxide improve the understanding of stratospheric ozone trends and their uncertainties
To facilitate scientific research using Aura's OMI nitrogen dioxide data, the team at developed a web-based monitoring system that shows time series for over 200 world cities and animated maps for larger regions.
The Northeast US has seen significant reductions in air pollution over its major metropolitan areas as communities grapple with widespread lockdowns and shelter-in-place orders as a result of the spread of COVID-19.
Aura's OMI data over South Asia show the means of the period in previous years, while the comparing to the means for 2020, showing a vast improvement after the nationwide stay-at-home order for India’s 1.3 billion citizens.
Satellite-derived emission estimates are based on NO2 measurements from the Aura Ozone Monitoring Instrument (OMI).
This study confirms the important role of monsoon regions in moistening the lower stratosphere in boreal summer using data collected from Aura's Microwave Limb Sounder (MLS) .
Observations from the Ozone Monitoring Instrument (OMI), onboard the NASA’s Earth Observing System (EOS) Aura satellite, reveal a large Sulfur dioxide pollution
