EOCIS: Lake Catchment Change Indicators V1.0

This dataset contains Lake Catchment Change Indicators data produced within the Earth Observation Climate Information Service (EOCIS) project by Plymouth Marine Laboratory.

The Product(s) can be used to map daily variations in the reflectance of water bodies contained in the target lake catchment. The derived quantities turbidity and chlorophyll-a can be used to determine variability in the optical and biochemical conditions of the lake and other included water bodies.

A set of vegetation, built-up area, and water indices are included to aid users in selection data ranges and locations of interest. These include the Normalized Difference Vegetation Index (NDVI), Normalized Difference Built-Up Index (NDBI) Augmented Normalized Difference Water Index (ANDWI) and Modified Normalized Difference Water Index (MDNWI).

These data sets have been created following the specific format for climate data at high resolution for the UK (CHUK) within the EOCIS project. The CHUK grid consists of 100m x 100m cells in British National Grid (BNG) projection. The CHUK grid covers the whole area of the British Isles, an area approximately 1,000km x 1,500km, whereas the data sets presented here are limited to parts of this grid for the extent of each lake catchment.

本数据集包含由普利茅斯海洋实验室（Plymouth Marine Laboratory）在地球观测气候信息服务（Earth Observation Climate Information Service, EOCIS）项目中生成的湖泊流域变化指标数据。
该产品可用于绘制目标湖泊流域内水体的日反射率变化情况。通过衍生得到的浊度与叶绿素-a数据，可用于分析湖泊及其他纳入研究的水体的光学与生化条件变化。
数据集附带了一系列植被、建成区与水体指数，以辅助用户筛选感兴趣的数据范围与研究区域。其中包括归一化差分植被指数（Normalized Difference Vegetation Index, NDVI）、归一化差分建成区指数（Normalized Difference Built-Up Index, NDBI）、增强型归一化差分水体指数（Augmented Normalized Difference Water Index, ANDWI）以及修正型归一化差分水体指数（Modified Normalized Difference Water Index, MDNWI）。
本数据集遵循EOCIS项目中英国高分辨率气候数据（Climate Data at High Resolution for the UK, CHUK）的特定格式生成。CHUK网格采用英国国家网格（British National Grid, BNG）投影，网格单元尺寸为100米×100米，覆盖整个不列颠群岛，总面积约为1000千米×1500千米；而本数据集仅限定于各湖泊流域范围内的部分网格区域。
