Global oceanic seamless POC concentration products derived from MODIS-Aqua

The dataset integrates seamless POC concentration daily products for the global ocean from 2003 to 2010, derived from MODIS-Aqua‘s XGBoost satellite retrieval products. It covers the time span from 2003 to 2010. The POC concentration in the product used int32 to integer data, specifically, the raw POC concentration (mg m-3) is first multiplied by 10000 and then rounded using int32.本数据集整合了2003至2010年全球海洋逐日无缝颗粒有机碳（Particulate Organic Carbon，POC）浓度产品，其数据源自中分辨率成像光谱仪Aqua卫星（MODIS-Aqua）的极限梯度提升（XGBoost）卫星反演产品。该数据集的时间跨度为2003年至2010年。本产品中的POC浓度采用int32整数数据格式存储，具体处理方式为：将原始POC浓度（单位：毫克每立方米，mg·m⁻³）先乘以10000，再通过int32格式完成取整操作。
