As an important resource, inland water is of great significance to human production and life. As a typical island independent water system, Hainan Province is generally rich in surface inland water resources and abundant in river runoff. However, due to the influence of dry and wet monsoon and terrain, it has the characteristics of uneven spatial and temporal distribution. At present, there are relatively few studies on the quality of inland water in Hainan Island. This product is based on the surface reflectance data of sentinel 2 on GEE cloud computing platform, combined with the measured data set, and uses three models of Fui, qaav6 and Fui based nutrient status to respectively retrieve the Fui, transparency and nutrient status of the inland water body of Hainan Island in the dry and wet seasons from 2019 to 2021. This data set can provide important scientific basis for the inland water quality monitoring, water pollution control and water ecological protection of Hainan Island.
