New Measurements of Trace Species in the Upper Troposphere from Infra-Red Spectra of the Atmosphere

摘要: The challenge of understanding our environment requires global measurements increasing numbers trace species and some priority to be given new observations classes which may play fundamental roles in climate chemistry interactions. Such compounds include “new” ozone depleting substances (ODS), greenhouse gases (GHGs) indirect controlling influences such as key chemical oxidants. For many these gases, relevant spectral signatures had, until recently, either not been well characterised globally or never observed the atmosphere. launch high-resolution spaceborne spectrometers, Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) on ENVISAT, is providing an unprecedented opportunity examine spectra atmosphere determine observable species. In this paper, MIPAS infra-red upper troposphere are examined, methods detecting weak atmospheric discussed gas demonstrated HCFC-22 ethane examples potential three-dimensional daily data gases.
