Climate change impacts on hydroxyl radical (OH) from the CiTTyCAT tropospheric chemistry model simulations

Hyroxyl radical, OH at the tropospheric level plays an important role as a cleansing agent in the atmosphere for atmospheric greenhouseandtrace gases. Hyroxyl radicalalsopreventsthe enhancement of these gases. Without OH, the Earth’s atmosphere chemical composition will be very different and might b...
