This map illustrates satellite-detected flood waters over the affected Southern & Lusaka Provinces, Zambia. Flooded areas have been sorted into 2 classes: Red areas represent standing flood waters identified with a high degree of confidence. Blue areas represent pre-flood water levels identified from 3 December 2007. Flood analysis was made using MODIS Terra & Aqua data recorded 16-19 February 2008. This flood detection is a preliminary analysis & has not yet been validated in the field. The rainfall estimate was derived from the Tropical Rainfall Monitoring Mission (TRMM) precipitation dataset at a spatial resolution of approximately 25km for this region. It is possible that precipitation levels may have been underestimated for local areas, and is not a substitute for ground station measurements.
