This product comprises different information layers as specified herein. Water Quality monitoring service concerns the measurement of the ‘apparent’ characteristics of the water retrieved through its reflectance/absorbance characteristics. The AfriCRS product is based on the federated Copernicus Lake Water Quality Products (lake water quality at coarse, medium and high spatial resolution) which provide a 10-days observation record for a large number (nominally 1,000) of medium and large-sized lakes, according to the Global Lakes and Wetlands Database (GLWD).
Lake Water Quality (LWQ), 300x300m
This product returns a two-band raster containing in Band 1 the mean turbidity of the water bodies observed over the observation period with a pixel range values from 0 to 100. Bad values = -1 and the out of roi = -1111. Band 2 gives the trohpic state index (TSI) obtained from chlorophyll-a observations averaged over the observation period. The TSI product has a value of 0, 10, 20, 30, 40, 50, 0, 70, 80, 90, 100 corresponding to chlorophyll classes which reflect the eutrophication status of a water body. The pixel range values are: 0 – 100 %, bad value = -1, Out of the ROI = -1111.
