SWI_JUP_LIMB_RASTER_PS
SWI JUP LIMB RASTER PS
Investigation of Jupiter’s stratospheric winds, temperature and composition, targeting one (or more) molecular line(s) at the planetary limb with a 3◦ resolution in latitude. The investigation of Jupiter’s stratospheric dynamics (winds) requires measuring the Doppler shifts induced by zonal winds on strong lines. The observations require a very high signalto-noise ratio (∼100) and a very high spectral resolution (100kHz). Similar requirements for the investigation of Jupiter’s stratospheric chemical inventory and temperature as a function of latitude. At each limb position, a short ∼10-point across-limb scan of the continuum emission is performed with the CCH to derive a posteriori the instrument pointing. Two CTS spectra are recorded for 60 seconds over 10000 channels (16 bits coding), and two CCH measurements (20 bits coding) are recorded for 0.1 second. Position-switch calibration method.

Scheduling: d1 for winds/temperature, d1/d2 for composition. Repetition: This mode is the baseline mode for SWI when the distance to Jupiter is < d1 (in order to cover all latitudes and longitudes with goal resolutions), except when other observation modes are used.
any rule that is used to schedule the observation: repetition rules, continuous (plasma instruments), one-off, every orbit, every day, etc
none
conditions that make the observation not possible (e.g. thruster firing)
