WebA widely used method for measuring upper-air ozone in situ up to altitudes of 30–35 km is through small, lightweight, and compact balloon-borne sondes. The reaction of ozone with potassium iodide in aqueous solution is used to measure the ozone concentration continuously in an electrochemical cell.

WebHowever, because of the sparseness of the ozone-sonde network, we are aware that the evaluation based on ozone-sonde observations can introduce large biases in regional and seasonal reanalysis performance (Miyazaki and Bowman, 2024). The reanalysis data have been co-located with observations through interpolation in time and space. WebRadiosondes measuring ozone concentration are known as ozonesondes.
