[Click to Expand Image] Map of the region of the DIMES field campaign, showing the tracer release point (cruise US1) and scatter plots of observed column integrated tracer (circles with radii proportional to concentration) from follow up cruises after 1 year (cruise US2), 2 years (cruise UK2), 2.5 years (cruise UK2.5) and 3 years (cruise US3). The simulated tracer concentration after 1 year (comparable to US2) is shaded from light blue to red. Credit: Ross Tulloch and John Marshall
