Cover. Joyce et al. doi:10.1002/2013SW000997 provided a plot of computed dose and dose equivalent rates for varying altitudes in the Earth and Mars atmospheres. Each curve is well described by a third order polynomial fit. The functional forms are provided to enable future studies to easily estimate atmospheric dose rates during times when CRaTER data is unavailable using measurements or estimations of the dose rate at 1AU through a similar level of shielding.
