Short summary

The accurate measurement of peroxy radicals is essential for understanding the chemistry of air masses probed in the free troposphere. The PeRCEAS instrument has been designed, developed and thoroughly characterised for the measurement of the total sum of peroxy radicals (RO₂^*) aboard airborne platforms. Parameters expected to affect the precision and accuracy of the measurement have been investigated in detail.
