Sea Surface Temperature (C)

Retirement Notice: This item is in mature support as of April 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 forecast 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. 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: Web Mercator Auxiliary Sphere 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. What can you do with this layer? Visualization: This layer can be used for visualization online in web maps and in ArcGIS Desktop. Analysis: This layer can be used as an input to geoprocessing tools and model builder. Units are in degrees Celsius, and there is a processing template to convert pixels to Fahrenheit. Do not use this layer for analysis while the Cartographic Renderer processing template is applied.服务停用通知：本产品自2024年4月起进入成熟支持阶段，并将于2026年12月正式停用。目前已有新版本可供使用，Esri建议您更新相关地图与应用以适配新版本。 海表温度（Sea Surface Temperature）是气候与气象观测的核心指标之一，广泛应用于天气预报、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场景。厄尔尼诺（El Niño）与拉尼娜（La Niña）是两类可通过海表温度地图进行预测的典型气候事件。 美国海军海洋局（Naval Oceanographic Office）的海表温度数据集基于卫星微波与红外影像计算生成，经最优插值处理后，可生成每日正午（12:00）全球海表温度地图。如需了解源数据详情，请查阅相关说明。 映射现象：海表温度 单位：摄氏度（Degrees Celsius） 时间间隔：每日 时间范围：2008年4月1日12:00:00 UTC 至今 像元大小：11千米 源数据类型：连续型 像素类型：浮点型（Floating Point） 数据投影：GCS WGS84 镶嵌投影：Web Mercator Auxiliary Sphere 覆盖范围：全球海洋 数据源：美国海军海洋局 ArcGIS Server URL：https://earthobs2.arcgis.com/arcgis 时间支持说明：本图层支持时间维度可视化。若启用时间动画，将显示当前时间范围内的平均海表温度；若禁用动画，则可通过图层的多维设置自定义时间范围。本图层默认展示时间范围内所有日期的平均海表温度，时间分辨率最小为1日，最大为1个月。 本图层的应用场景： 可视化：可在线用于Web地图以及ArcGIS Desktop中的数据可视化。 分析：可作为地理处理工具与模型构建器的输入数据源。本图层单位为摄氏度，同时提供处理模板可将像素值转换为华氏度。请注意：若启用制图渲染器（Cartographic Renderer）处理模板，则不得将本图层用于分析操作。
