Carbonyl Sulfide (OCS) TOMCAT Model Data

These data are monthly mean carbonyl sulfide (OCS) model mixing ratios between 2004 and 2018. We use the TOMCAT/SLIMCAT 3-D off-line chemical transport model (Chipperfield, 2006). The model reads in 6-hourly fields of temperature, humidity, vorticity, divergence and surface pressure from ECMWF ERA-INTERIM meteorological (re)analyses. Horizontal resolution of 2.8° × 2.8° with 60 hybrid σ-pressure levels from the surface to ~60 km. The model dataset TOMCATOCS is defined in the files as 'OCS_SOIL_2_5_mm'. We recommend using this variable for any reproductions of the publication plots. TOMCATCON and TOMCATSOTA available upon request.
