The spring deployment began with a focus on capturing the initial sea ice conditions.On 28 May, the passage of an Arctic cyclone across the Lincoln Sea on 27 May resulted in a thinning of the cloud layer, relatively low predicted AODs (< 0.1) from the NASA Goddard Earth Observing System forward processing (GEOS-FP, see Section 7d) model, and decreasing relative humidity at mid-levels (500-700 hPa) over the buoy region, which was covered with fresh snow.Strong northerly winds persisted over the Canadian Archipelago and contributed to the cold air advection toward Ellesmere Island and across the Lincoln Sea.The northerly wind combined with a developing cyclone over northern Baffin Bay, and together with a strong northeasterly flow at the surface through the Nares Strait, effectively transported the surface air mass from the Lincoln Sea into Baffin Bay.These factors produced cloud-free conditions over the Lincoln Sea, supporting the SIMB survey flight (RF1, P-3B only, Table S1).After a high-altitude transit from Pituffik, the SIMB survey consisted of a mix of high-altitude and low-altitude legs and a square spiral over Buoy O on 28 May.The aircraft returned at low altitude (< 250m) via the Nares Strait, where high winds at flight level (15 to 25 m s -1 ), blowing snow over sea ice, and sea spray over the polynya, were observed, as well as a gradient in aerosol size distribution and hygroscopicity.On this and many subsequent flights, the aircraft also passed near the long-term gr...
