Zambezi River, Zambia. credit: ESA
This colourful image shows the Zambezi River’s floodplain in Zambia. The image was created from three acquisitions from Envisat’s radar instrument that were merged together. Each acquisition was assigned a colour and when combined show changes in the floodplain between each satellite acquisition.
The white patch of pixels in the upper right quadrant marks the city of Mongu and appears white as few changes occur between each satellite image. In light green and running up the center of the image you can track the main channel of the Zambezi river. However, one image was taken during the wet season when the water levels rise up to the edge of the town. The range of colours in the image attest to the dramatic changes in water level of the Zambezi between wet and dry seasons.
