Abstract Radio occultations are commonly used to determine vertical profiles of ionospheric electron density and neutral atmospheric density from measurements of frequency. Previous work has developed expressions for how uncertainties in electron density and neutral density depend on uncertainty in frequency. However, these expressions assume that the relevant density decreases exponentially with increasing altitude, which limits their applicability. Here we develop alternative expressions for uncertainties in radio occultation experiments. We find that uncertainties depend on the vertical resolution. We validate these expressions on radio occultation observations by Mars Global Surveyor and MAVEN. These expressions can be used to perform preliminary design studies of future radio occultation experiments.
