OBSERVATION OF DUST LOADINGS FROM SPACE-BORNE MEASUREMENTS (2005–2016) [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
Dust particles of different size and origins, form major part of air pollution in the atmosphere. The qualitative and quantitative estimates of dust from ground-based measurements provide accurate information at regional scales.

A global catalogue of large SO₂ sources and emissions derived from the Ozone Monitoring Instrument [PDF]

Atmospheric Chemistry and Physics, 2016
Sulfur dioxide (SO2) measurements from the Ozone Monitoring Instrument (OMI) satellite sensor processed with the new principal component analysis (PCA) algorithm were used to detect large point emission sources or clusters of sources. The total of 491

Seasonal, interannual and decadal variability of tropospheric ozone in the North Atlantic: comparison of UM-UKCA and remote sensing observations for 2005–2018 [PDF]

Atmospheric Chemistry and Physics, 2023
Tropospheric ozone is an important component of the Earth system as it can affect both climate and air quality. In this work, we use observed tropospheric column ozone derived from the Ozone Monitoring Instrument (OMI) and Microwave Limb Sounder (MLS ...

Ozone Monitoring Instrument (OMI) Total Column Water Vapor version 4 validation and applications [PDF]

Atmospheric Measurement Techniques, 2019
Total column water vapor (TCWV) is important for the weather and climate. TCWV is derived from the Ozone Monitoring Instrument (OMI) visible spectra using the version 4.0 retrieval algorithm developed at the Smithsonian Astrophysical Observatory.

Improvements to the OMI near-UV aerosol algorithm using A-train CALIOP and AIRS observations [PDF]

Atmospheric Measurement Techniques, 2013
The height of desert dust and carbonaceous aerosols layers and, to a lesser extent, the difficulty in determining the predominant size mode of these absorbing aerosol types, are sources of uncertainty in the retrieval of aerosol properties from near-UV ...

A 16-year global climate data record of total column water vapour generated from OMI observations in the visible blue spectral range [PDF]

Earth System Science Data, 2023
We present a long-term data set of 1∘×1∘ monthly mean total column water vapour (TCWV) based on global measurements of the Ozone Monitoring Instrument (OMI) covering the time range from January 2005 to December 2020. In comparison to the retrieval

Improved satellite retrievals of NO₂ and SO₂ over the Canadian oil sands and comparisons with surface measurements [PDF]

Atmospheric Chemistry and Physics, 2014
Satellite remote sensing is increasingly being used to monitor air quality over localized sources such as the Canadian oil sands. Following an initial study, significantly low biases have been identified in current NO2 and SO2 retrieval products from the
