Abstract

Transport and mixing in fronts was a Natural Environment Research Council (NERC) Polluted Troposphere Research Programme project (Round 1 - NER/T/S/2002/00149 - Duration 2002 - 2005) and was led by DR SL Gray, University of Reading. The data consists of the rate at which frontal regions in weather systems transport polluted air from the boundary layer to the free troposphere using very high-resolution model simulations backed up by observations. These simulations were made using the Met Office operational unified model (UM) run locally at the University of Reading.

These contain 3D tracer distributions from 02UTC 09/05/05 - 02UTC
10/05/05 for four separate tracers.
-Field 71 is the tracer transported by advection only,
-field 72 is the tracer transported by advection and mixing,
-field 73 is the tracer transported by advection, mixing and convection and
-field 74 is the tracer transported by advection, mixing and convection.
