Short summary

We investigate the sensitivity to polarisation of geoCARB, a proposed geostationary mission to measure column-averaged concentrations of CO2, CH4 and CO from spectra of reflected sunlight, through analysis of an ensemble of simulated polarised spectra for targets in India, China and Australia. Although geoCARB will not carry polarisers or polarisation scramblers, we show that the effects of polarisation can be minimised provided the polarisation signature of geoCARB is calibrated before flight.
