This map illustrates estimated total rainfall accumulation for Vietnam. This total estimate was derived from the Tropical Rainfall Monitoring Mission (TRMM) precipitation dataset at a spatial resolution of approximately 25km for this region, and covers the dates from 25 October to 04 November 2008. It is possible that precipitation levels may have been underestimated for local areas, and is not a substitute for ground station measurements. This rainfall estimate is a preliminary result & has not yet been validated in the field.

The depiction and use of boundaries, geographic names and related data shown here are not warranted to be error-free nor do they imply official endorsement or acceptance by the United Nations. This map was produced by the United Nations Institute for Training and Research (UNITAR) Operational Satellite Applications Programme (UNOSAT).
