Google Earth Engine——全球海洋颜色、叶绿素、反射率和颗粒有机碳等数据集

2024-02-02 11:44:26 浏览数 (1)

This level 3 product includes ocean color and satellite ocean biology data produced or collected under EOSDIS.

This dataset may be used for studying the biology and hydrology of coastal zones, changes in the diversity and geographical distribution of coastal marine habitats, biogeochemical fluxes and their influence in Earth's oceans and climate over time, and finally the impact of climate and environmental variability and change on ocean ecosystems and the biodiversity they support.

Scale factor and offset are already applied.

  • There are number of missing data dates in this dataset. For example, most dates are missing between 2009-04-29 and 2009-12-01.
  • The estimated values for POC might be a result of the data being generated without a scale. For more information, visit the Ocean Color Forum. SeaWiFS OceanData

这个3级产品包括在EOSDIS下产生或收集的海洋颜色和卫星海洋生物学数据。

这个数据集可用于研究沿海地区的生物学和水文学、沿海海洋生境的多样性和地理分布的变化、生物地球化学通量及其在地球海洋和气候中的影响，以及最后研究气候和环境变异性和变化对海洋生态系统及其支持的生物多样性的影响。

已经应用了比例因子和抵消。

处理历史

在这个数据集中，有许多数据丢失的日期。例如，大多数日期在2009-04-29和2009-12-01之间缺失。

POC的估计值可能是由于数据生成时没有标尺。欲了解更多信息，请访问海洋色彩论坛。
