How to mesure ozone at high altitude?

Hi

I'm looking for a way to measure ozone gas when its cold (no I mean like really cold :) ) and at very high altitudes (30 000 m). However most ozone sensors only seem to work until around -10° C. Does anyone know a way to solve this (a special sensor or so)?

I can’t help, but I’m really curious to know how you will get the sensor up there?

Keep the sensor in a warmed compartment, and draw gas samples into it.

All the rest of the electronics have to be kept warm, so put the sensor in the same compartment and do what jremington suggested.
