TOMCAT Tropospheric Ozone

Global 3-D simulations of tropospheric ozone (TO3) from the TOMCAT chemical transport model (2008-2017) output at two satellite local solar overpass times (09.30 & 13.30 LST). The ozone data (2-daily overpass times) is provided as 3-D fields on the 2.8°×2.8° horizontal model grid. Atmospheric pressure (Pa) and temperature (K) have also included to provide vertical information on the ozone distribution up to 10 hPa. The ozone data has units of mass mixing ratio (1.0E-9). This work was undertaken primarily as long-term science activities of the NERC - National Centre for Earth Observation.

These model runs were used in the accepted (2024) manuscript in Atmospheric Chemistry and Physics (ACP) titled "Quantifying the tropospheric ozone radiative effect and its temporal evolution in the satellite-era". The DOI for the preprint is doi: 10.5194/egusphere-2023-1513.
