Description

<jats:title>Abstract</jats:title><jats:p>No direct observational evidence of sprite‐produced active radicals has been presented owing to the difficulty of observing a small event area in the nighttime mesosphere, whereas sprite chemical models have indicated that sprite discharge locally affects the atmospheric composition. We present the first observational evidence of a HO<jats:inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="graphic/grl60090-math-0004.png" xlink:title="urn:x-wiley:grl:media:grl60090:grl60090-math-0004"/>production above sprite‐producing thunderstorms from the coincidence of temporal‐spatial observations of HO<jats:inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="graphic/grl60090-math-0005.png" xlink:title="urn:x-wiley:grl:media:grl60090:grl60090-math-0005"/>spectra, sprite events, and thunderstorms by two space instruments, a submillimeter‐wave limb spectrometer and ultraviolet/visible Imager and a ground‐based very low frequency radiation lightning detection network. A total of three areas was identified with enhanced HO<jats:inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="graphic/grl60090-math-0006.png" xlink:title="urn:x-wiley:grl:media:grl60090:grl60090-math-0006"/>levels of approximately 10<jats:inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="graphic/grl60090-math-0007.png" xlink:title="urn:x-wiley:grl:media:grl60090:grl60090-math-0007"/>molecules. A chemical sprite model indicates an increase in HO<jats:inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="graphic/grl60090-math-0008.png" xlink:title="urn:x-wiley:grl:media:grl60090:grl60090-math-0008"/>in the considered altitude region; however, the predicted production due to a single sprite event is smaller than the observed enhancement. Our observational results suggest that sprites potentially contribute 1% of nighttime background HO<jats:inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="graphic/grl60090-math-0009.png" xlink:title="urn:x-wiley:grl:media:grl60090:grl60090-math-0009"/>generation at altitudes of 75–80 km globally.</jats:p>
