Scientists at the Earth Resources Observation and Science (EROS) Center have developed an algorithm that fuses Landsat 8 and Sentinel-2 data in a way that generates more accurate daily evapotranspiration (ET) maps with a much higher spatial resolution.

That’s big news for those working in such fields as hydrology, climatology, ecology, and agriculture, where the quantification of actual water consumption is essential and critical. The fused data will mean additional support and benefits to policy makers and water managers trying to make informed decisions on sustaining limited water resources.
