Observations of backscattered near-ultraviolet radiation from the Total Ozone Mapping Spectrometer (TOMS) on board the Nimbus-7 (1979–92) and the Earth Probe (mid-1996 to present) satellites have been used to derive a long-term record of aerosol optical depth over oceans and continents. The retrieval technique applied to the TOMS data makes use of two unique advantages of near-UV remote sensing...

[1] One year (December 2003 to November 2004) of Terra Moderate Resolution Imaging Spectroradiometer (MODIS), Total Ozone Mapping Spectrometer (TOMS), and Measurement of Pollution in the Troposphere (MOPITT) data over the open ocean are used in conjunction with the Goddard Chemistry Transport Model (GOCART) to characterize differing aerosol types as a function of satellite observable parameters...

This study investigates anomalous ozone distributions over cloudy areas in Nimbus-7 (N7) and Earth-Probe (EP) TOMS version-7 data and analyzes the causes for ozone anomaly formation. A 5◦-longitude by 5◦-latitude region is defined to contain a Positive Ozone Anomaly (POA) or Negative Ozone Anomaly (NOA) if the correlation coefficient 5 between total ozone and reflectivity is ≥0.5 or ≤−0.5. The ...

[1] In this paper we present validation results of the total ozone column data products of the Ozone Monitoring Instrument (OMI) on board the NASA EOS-AURA satellite through comparisons with ground-based observations by Dobson and Brewer spectrophotometer instruments. Quality-controlled and archived total ozone column data from these ground-based instruments located at stations worldwide have b...

[1] A new algorithm to retrieve total column ozone from global spectral UV irradiance measurements is presented, and its accuracy is assessed. The expanded uncertainty (coverage factor 2) of the resulting ozone values varies between 2% and 3.5% for solar zenith angles (SZA) smaller than 75 and clear skies. For larger SZA the uncertainty becomes dominated by the sensitivity of the method to the ...

[1] We investigate the modulation of aerosols by the Madden-Julian Oscillation (MJO) using multiple, global satellite aerosol products: aerosol index (AI) from the Total Ozone Mapping Spectrometer (TOMS) on Nimbus-7, and aerosol optical thickness (AOT) from the Moderate Resolution Imaging Spectroradiometer (MODIS) on Terra and Aqua and the Advanced Very High Resolution Radiometer (AVHRR) on NOA...

In contrast to classical game theoretic analysis of simultaneous and sequential play in bimatrix games, Steven Brams has proposed an alternative framework called the Theory of Moves (TOM) where players can choose their initial actions and then, in alternating turns, decide to shift or not from its current action. A backward induction process is used to determine a non-myopic action and equilibr...
