Tropospheric SO2 and NO2 in 2012–2018: Contrasting views of two sensors (OMI and OMPS) from space

Atmospheric Environment, 2020
Abstract The global long-term Climate Data Records (CDRs) of atmospheric SO2 and NO2 have been obtained from multiple satellite sensors since 1990s, and all these CDRs show consistently decreasing trends in developed countries and increasing trends in developing countries prior to 2010.

Aerosol Absorption Measurements from Space Observations by the Aura‐OMI Sensor

AIP Conference Proceedings, 2009
In spite of the progress in space‐borne aerosol sensing capability over the last decade, the quantification of the net effect of aerosols on the radiative transfer balance of the earth‐atmosphere system remains a challenge. Observational evidence as well as important theoretical analyses, indicate that the absorption of solar radiation by soot ...

Spatially continuous mapping of daily global ozone distribution (2004–2014) with the Aura OMI sensor

Journal of Geophysical Research: Atmospheres, 2016
AbstractTotal ozone data from the Aura Ozone Monitoring Instrument (OMI) play an important role in the monitoring of the spatial distribution and temporal change of total ozone. However, since September 2005, and especially after mid‐2006, due to row anomalies in the OMI instrument, one third to one half of the OMI total ozone data has been missing. In

Satellite Product Evaluation of the OMI/AURA Sensor for the Nitrogen Dioxide Analysis in the Province of Buenos Aires

2018 IEEE Biennial Congress of Argentina (ARGENCON), 2018
La contaminacion atmosferica resulta actualmente una de la principales problematicas ambientales a nivel mundial, tanto por su incidencia en el cambio climatico como por los riesgos que presenta a la salud publica. Las altas concentraciones de oxidos de nitrogeno son un indicador de la mala calidad del aire ambiente, teniendo como principal fuente de ...

Investigation of Behavior and Trend of Nitrogen Dioxide in Tehran Using OMI Satellite Sensor Measurements

2017
Air pollution is one of the most important problems in the world’s major cities in the last century because it endangers human health and the environment. One of the indicators of air pollution is nitrogen dioxide, which is continuously measured by satellite from space and via ground-based instruments.

Geos-chem adjoint inversion of SO2 and NOx emissions with multi-sensor (OMPS, OMI, and VIIRS) data over China

2019
<p>Accurate and timely SO2 and NOx emission inventories are required to simulate and forecast SO2 and NO2 concentrations in the atmosphere. However, bottom-up emission inventories have a time lag of at least one year, as it takes time to collect necessary activity rates and emission factors.
