Aerosols and surface UV products from Ozone Monitoring Instrument observations: An overview
Omar Torres,A. Tanskanen,Ben Veihelmann,Changwoo Ahn,Remco Braak,Pawan K. Bhartia,Pepijn Veefkind,P. F. Levelt +7 more
TL;DR: In this article, an overview of the theoretical and algorithmic aspects of the Ozone Monitoring Instrument (OMI) aerosol and surface UV algorithms is presented, along with several validation and evaluation analysis carried out to assess the current level of uncertainty of these products.
Journal ArticleDOI
Global assessment of OMI aerosol single-scattering albedo using ground-based AERONET inversion
TL;DR: In this article, the authors compare the aerosol single-scattering albedo (SSA) retrieved by the near-UV two-channel algorithm (OMAERUV) applied to the Aura/Ozone Monitoring Instrument (OMI) measurements with an equivalent inversion made by the ground-based Aerosol Robotic Network (AERONET).
Journal ArticleDOI
Assessment of OMI near‐UV aerosol optical depth over land
TL;DR: In this paper, a comprehensive assessment of the aerosol optical depth (AOD) product retrieved from the near-UV observations by the Ozone Monitoring Instrument (OMI) onboard the Aura satellite is presented.
Journal ArticleDOI
Comparison of Ozone Monitoring Instrument UV Aerosol Products with Aqua/Moderate Resolution Imaging Spectroradiometer and Multiangle Imaging Spectroradiometer observations in 2006
TL;DR: In this article, an assessment of the consistency of the Ozone Monitoring Instrument (OMI) aerosol products with the results from other satellite aerosol sensors is performed, including the UltraViolet Aerosol Index (UVAI), aerosol Absorption Optical Depth (AAOD), and aerosol extinction optical depth (AOD).
Journal ArticleDOI
Impact of the ozone monitoring instrument row anomaly on the long-term record of aerosol products
TL;DR: In this article, the effect of the reduced spatial coverage on the monthly average values of retrieved aerosol optical depth (AOD), single scattering albedo (SSA) and the UV Aerosol Index (UVAI) using the 2005-2007 three-year period prior to the onset of the row anomaly was carried out.
