Tropospheric ozone profiles from a ground-based ultraviolet spectrometer: a new retrieval method.

A New Retrieval Method for Tropospheric Ozone Profiles from a Ground-based Ultraviolet Spectrometer

Tropospheric Ozone Profile Retrievals from an Airborne Ultra- violet/Visible Spectrometer

We present a novel technique to retrieve ozone profiles, and especially, tropospheric ozone (O3) from airborne Ultraviolet-Visible (UV) spectrometer measurements. The profile retrieval is possible by viewing a variety of zenith angles from down-looking and up-looking directions, taking advantage of O3 absorption in the Huggins (300-340 nm) and the Chappuis bands (530-650 nm). Measurements are n...

Validation of version 5.20 ILAS HNO3, CH4, N2O, O3, and NO2 using ground-based measurements at Arrival Heights and Kiruna

Ground-based measurements of O3 and NO2 columns at Kiruna (68°N) and Arrival Heights (78°S) were used to validate stratospheric profile measurements of the same species by the satellite-based Improved Limb Atmospheric Spectrometer (ILAS) flown between November 1996 and June 1997. In addition, measurements of HNO3, CH4, and N2O made at Arrival Heights are compared with measurements of these spec...

Simulated observation of tropospheric ozone and CO with the Tropospheric Emission Spectrometer (TES) satellite instrument

[1] The Tropospheric Emission Spectrometer (TES) on board NASA’s Aura satellite (to be launched in 2004) will provide measurements of global distributions of ozone, CO, and other key chemical species in the troposphere. In order for TES to meet a design lifetime of 5 years, it has been determined that a global survey strategy with 50% duty cycle must be identified. In this study, simulated conc...

Capturing time and vertical variability of tropospheric ozone: A study using TES nadir retrievals

[1] In this paper, the vertical resolution for Tropospheric Emission Spectrometer (TES) nadir ozone retrievals is established and is used to assess the ability of TES to capture time variations of ozone in the troposphere. This characterization is based on retrievals of ozone using simulated radiances generated from ozonesonde profiles taken over Bermuda from 14 April to 25 May 1993. To that en...
