In addition to the observations, the WRF 3.6.1 with OSU BPRC polar optimizations (Polar WRF) was run twice daily to help in mission planning. Further, one of the main scientific goals of the campaigns was to provide an observational data base of 3-D wind information to compare with and validate the performance of mesoscale models and reanalysis fields in the polar regions. This will be discussed for the campaigns as a whole and for the low level circulations investigated
Individual missions were flown to investigate lower tropospheric circulations such as the Greenland Tip Jet, barrier winds off the southeast coast of Greenland, katabatic flows near the coast lines, and boundary layer rolls and organized large eddies (OLEs) over the water and transitional ice zones. Observational analysis for these cases will be presented along with model-observation comparison, particularly for the barrier wind case where post-experiment research versions of the high resolution WRF with varying horizontal and vertical resolutions were also run.
