Arctic Sea Surface Temperature (C)

Retirement Notice: This item is in mature support as of October 2024 and will be retired in December 2026. A new version of this item is available for your use. Esri recommends updating your maps and apps to use the new version. Sea Surface Temperature is a key climate and weather measurement used for weather prediction, ocean forecasts, tropical cyclone forecasts, and in coastal applications such as fisheries, pollution monitoring and tourism. El Niño and La Niña are two examples of climate events which are forecasted through the use of sea surface temperature maps. The Naval Oceanographic Office sea surface temperature dataset is calculated from satellite-based microwave and infrared imagery. These data are optimally interpolated to provide a daily, global map of the midday (12:00 pm) sea surface temperature midday. Learn more about the source data. Phenomenon Mapped: Sea Surface Temperature Units: Degrees Celsius Time Interval: Daily Time Extent: 2008/04/01 12:00:00 UTC to present Cell Size: 11 km Source Type: Continuous Pixel Type: Floating Point Data Projection: GCS WGS84 Mosaic Projection: Alaska Polar Stereographic (WKID 5936) Extent: Global Oceans Source: Naval Oceanographic Office ArcGIS Server URL: https://earthobs2.arcgis.com/arcgis Time: This is a time-enabled layer. It shows the average sea surface temperature during the map's time extent, or if time animation is disabled, a time range can be set using the layer's multidimensional settings. The map shows the average of all days in the time extent. Minimum temporal resolution is one day; maximum is one month.

停用通知：本数据集自2024年10月起进入成熟支持阶段，将于2026年12月正式停用。当前已有新版本可供使用，Esri (环境系统研究所) 建议您更新相关地图与应用程序以适配新版本。

海表温度 (Sea Surface Temperature) 是用于天气预报、海洋预报、热带气旋预报，以及渔业、污染监测、滨海旅游等海岸带应用的关键气候与气象观测指标。厄尔尼诺（El Niño）与拉尼娜（La Niña）即为两类可通过海表温度地图开展预报的典型气候事件。

本数据集由美国海军海洋局基于星载微波与红外影像计算生成，经最优插值处理后可输出全球每日正午（12:00 UTC）海表温度栅格地图。如需了解源数据的详细信息，请查阅相关说明。
