Short summary
Hydrometerologial data in Brazil is becoming increasingly more accessible in recent years, but data gaps still exist in many regions. In our work, we tested some statistical ways to explore the existing data and fill gaps in evaporation estimates, based on the assumption that evaporation and precipitation are inversely related. This could be useful for extending evaporation series into the past, for example for hydropower reservoir planning and flow forecast.
