Short summary

We describe a portable calibration source of nitric oxide (NO) based on the photolysis of nitrous oxide. Combining this with a previous photolytic ozone (O₃) source yields a calibrator that produces known mixing ratios of NO, O₃, and nitrogen dioxide (NO₂); NO₂ is produced by the reaction of NO with O₃. This portable NO₂/NO/O₃ calibration source requires no external gas cylinders and can be used as a standard to calibrate O₃ and NO_x air pollution monitors in the field.
