- Evapotranspiration - NASA Earthdata
Evapotranspiration (ET) is the sum of water evaporation from the land surface and its transpiration, or movement, through vegetation ET measurements are useful in monitoring and assessing water availability, drought conditions, and crop production An increase in available energy from the Sun through reductions in cloud cover, seasonal lengthening of daylight, and similar variables favors

- Glacier Power: How do Glaciers Move? - NASA Earthdata
Glacier Advance and Retreat Glaciers advance and retreat If more snow and ice are added than are lost through melting, calving, or evaporation, glaciers will advance If less snow and ice are added than are lost, glaciers will retreat Accumulation Zone: Where snow is added to the glacier and begins to turn to ice Input Zone: In this zone, the glacier gains snow and ice
- Glacier Power: What is Glacier Anatomy? | NASA Earthdata
The accumulation (input) zone is where a glacier gains snow and ice through snowfall and compression Ice begins to flow like a conveyor belt, driven by gravity and ever mounting snows In the lower region or ablation (output) zone, the glacier loses ice through melting and evaporation Older ice is carried down to greater and greater depth An equilibrium line divides the two areas This spot
- Runoff - NASA Earthdata
Runoff is the measurement of the flow of water into a lake, stream or other waterbody, usually expressed in cubic feet per second The flow is produced by rainfall from storms, precipitation accumulation or transpiration, melting ice or snow, seepage, evaporation, and percolation
- To the Lighthouse - NASA Earthdata
The researchers used the data from the instruments on the lighthouse to calibrate and verify satellite remote sensing for a lake-wide estimate of evaporation “Quantifying evaporation is the hardest part of this study,” said Pakorn Petchprayoon, a researcher from Geo-Informatics and Space Technology Development Agency in Thailand
- Dead Sea and Salt Evaporation Ponds - NASA Earthdata
Dead Sea and Salt Evaporation PondsThe data from the two instruments aboard the four satellites are processed through a set of algorithms to make the imagery consistent and comparable across the instruments This includes atmospheric correction, cloud and cloud-shadow masking, spatial co-registration and common gridding, illumination and view angle normalization, and spectral bandpass adjustment
