Atmospheric and oceanic data used in the Unprecedented Open-Ocean Polynya in Breid Bay, East Antarctica in Winter 2024

Daily July–August 2024 values of absolute (ABS) and anomaly (ANOM) fields of sea-ice concentration (SIC) and associated atmospheric and oceanic variables averaged over the Breid Bay polynya region (16-31°E, 65-68°S). Days influenced by atmospheric river (AR) events affecting the polynya region are highlighted in bold. For each variable, the maximum daily anomaly within the polynya region is used, except for the 10-m meridional wind (V10), for which the minimum anomaly is reported. The anomalies of Ekman suction, surface latent heat flux (SLHF), surface sensible heat flux (SSHF), surface thermal radiation (STR; longwave radiation), and surface solar radiation (SSR; shortwave radiation), averaged over the Breid Bay polynya region (16-31°E, 65-68°S). For each variable, the maximum daily anomaly within the polynya region is reported.本数据集涵盖2024年7月至8月期间，布莱德湾冰间湖（Breid Bay polynya）区域（东经16°-31°、南纬65°-68°）内平均得到的海冰密集度（sea-ice concentration, SIC）及其相关大气、海洋变量的绝对场（absolute field, ABS）与距平场（anomaly field, ANOM）逐日数据。对影响该冰间湖区域的大气河（atmospheric river, AR）事件波及的日期，采用加粗格式予以标注。针对各变量，本数据集取用该冰间湖区域内的逐日最大距平值，仅10米经向风（10-m meridional wind, V10）采用逐日最小距平值。 本数据集同时包含布莱德湾冰间湖（Breid Bay polynya）区域（东经16°-31°、南纬65°-68°）内平均得到的埃克曼抽吸（Ekman suction）、表面潜热通量（surface latent heat flux, SLHF）、表面感热通量（surface sensible heat flux, SSHF）、表面热辐射（surface thermal radiation, STR；长波辐射）以及表面太阳辐射（surface solar radiation, SSR；短波辐射）的距平逐日数据。针对上述所有变量，均取用该冰间湖区域内的逐日最大距平值。
