SCIENTIFIC ABSTRACT
We propose to make spectroscopic observations of the giant planets
(Jupiter, Saturn, Uranus and Neptune) using the LWS and SWS instruments.
In addition, some CAM-CVF and PHOT-S observations will be made. The
scientific goals are:
- To make complete spectral surveys using the SWS and LWS, with
additional dedicated observations of particular lines. This will
allow the determination of the concentrations of the most important
atmospheric species, and will establish a chemical inventory of the
atmospheric composition, which will assist in characterising the
tropospheric and stratospheric chemistry.
- To establish the deuterium:hydrogen (D:H) and helium:hydrogen (He:H)
ratios in the atmospheres of the giant planets. This will shed light
on their primordial abundances and on the formation of the solar
system.
- To investigate the transport of material from the deep atmosphere
through the tropopause into the stratosphere.
- To investigate the effects of clouds on the FIR continuum emission.
A full discussion of the scientific case is give in the CP programmes of
the LWS Solar System SAG and the Mission Scientists.
