NRT Observations

Some of the main parameters describing aerosol absorption coefficient (and ancillary data) observed during campaign are plotted here in Near Real Time,
site by site. Raw and unscreened data are represented and may not have final calibration applied.

The WRF-CHIMERE modelling system has been implemented over the Emilia Romagna region for simulating atmospheric gases and aerosols formation, diffusion and removal processes on regional scale.

Meteo

A meteorological forecast over the whole national territory is performed using non-hydrostatic Numerical Weather Model "Moloch" developed by CNR-ISAC. Moloch forecast (horizontal resolution about 1,5 km) is computed daily in operational mode in CNR-SAC. Here some forecast products are presented.

Backtrajectories

Flexpart lagrangian simulations allow to characterize the source-receptor relation of atmospheric tracers in the framework of long range and mesoscale transport. For the ACTRIS campaign a 1000 back-trajectories cluster is released every 6 hours from a 3D box of 0.5°x0.5°x500m dimensions over each measurement sites, travelling back in time for 4 days
