This is a FLEXPART model version tailored to use with the meteorological output data generated by the Norwegian Earth System Model (NorESM1-M). The atmospheric component of the NorESM1-M is based on the Community Atmosphere Model (CAM4) ; hence, this FLEXPART version is widely applicable and it provides a tool to directly analyze and diagnose atmospheric transport properties of state-of-the art climate models in a reliable way.

Conserved tracer-averaged residence time in the lowest 1 km of the atmosphere for 21-days backward in time plume, for Summit and Birkenes stations. Results are averaged over 5 years (1995–2000) for the months JJA. Values are divided for the surface of the grid sampling cell.
