NAWDIC-ARM

The ARM-ENA site in the Azores is partnering with NAWDIC to synergize scientific objectives by providing additional radiosounding observations during IOPs of NAWDIC components. Together, the new observations will enable detailed studies of the complex dynamical and thermodynamical interactions shaping the boundary layer and its interfaces with the ocean surface and the free troposphere during the passage of midlatitude cyclones and atmospheric rivers in the region. During the measurement period and according to the forecasted weather systems in the Eastern North Atlantic, IOPs will be defined, for which at least one airborne platform of NAWDIC will operate. During IOPs two additional radiosondes will be launched in addition to the 2 routine launches at the ARM-ENA site.

The additional sounding profiles will (i) enhance the array of atmospheric observations during IOPs of interest including DI and Atmospheric Rivers  in a critical, data-scarce area such as the Central-Eastern Atlantic; (ii) provide detailed structure of the cold front and PBL before, during and recovering from DIs; (iii) be compared to remotely sensed data and will be used for calibration and assessment of uncertainties; (iv) serve to better initialize NWP models and help evaluate their representation of the atmospheric processes by data-denial experiments; (v) complement additional radiosondes launched by universities in Europe and through E-ASAP from ships over the North Atlantic.
