This picture shows a comparison of different annual mean OH fields (in units 106 molecules/cm3) in a study that evaluates multi-model simulations of carbon monoxide (CO) and ozone (O3) in the Arctic and over lower latitude emission regions, as part of the POLARCAT Model Inter-comparison Project (POLMIP).
