Supplementary material to "Variability of ice supersaturated regions at flight altitudes: evaluation of ERA5 reanalysis using IAGOS in situ measurements"

S1 Effect of sample size on resultsIn the evaluation of ERA5 using IAGOS, we are highly dependent on the number of available measurements from IAGOS.If we do not have enough measurements, our conclusions may not be representative.Hence, in this appendix, we explore the effect of the sample size on temperature, relative humidity over ice (RHi), the ice supersaturated region (ISSR) fraction, and the equitable threat score (ETS).
