Hydrologic applications for water planning and water balances require datasets for climate parameters, such as precipitation and temperature, that cover a territory on a continuous basis. However, meteorological stations are often unevenly distributed.
The Gridded Meteorological Ensemble Tool (GMET) enables water managers to use station data to generate continuous, historic climate grids for an area, along with statistical information that can provide an estimate of the level of uncertainty.
This brief describes SEI’s effort to use GMET in Bolivia, as a key input for the country’s water balance study. The study consisted of a comprehensive model of water availability in its rivers, lakes and streams.
