Valentina Aquila has published research involving the TTL (Tropical Tropopause Layer) in climate-chemistry models, which studies aerosol transport and ozone.
The "TTL model" approach relies on the flash communicating directly with the camera to handle exposure changes during movement. valentina TTL model
