Certain sources of inaccuracy must be kept in mind when considering errors in ozone measurements. Errors can originate from the ozone sensor cell, the interface (converter), temperature and flow rate measurement, telemetry, or they can be random errors. The measurement procedure affects the accuracy. For example, if you measure only ozone partial pressure, you can do measurements in a way which is slightly different from the method you use when calculating total ozone in the end. It is also possible to improve measurement accuracy by developing the measurement methods in the sensing system.
Basic sources for errors and differences between measurement systems (the ECC system, light absorption measurement) are quite well known. Relevant literature is also available. See Performance Review Literature.
