- Evaporation - NASA Earthdata
The physical process by which a liquid or solid is transformed to the gaseous state; the opposite of condensation
- 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
- Hurricanes - NASA Earthdata
NASA's hurricane data give researchers and decision makers critical information for understanding and responding to these powerful, hazardous storms
- Glacier Power: How do Glaciers Move? | NASA Earthdata
Ablation Zone: Where the glacier loses ice through melting, calving, and evaporation Output Zone: In this zone, the glacier loses ice This is the lower region of the glacier Meltwater flows out to the terminus through hidden channels and tunnels Oldest ice is the deepest Equilibrium Line: An equilibrium line divides the two areas
- 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
- Dead Sea and Salt Evaporation Ponds - NASA Earthdata
True-color image of the Dead Sea (the dark body of water) and salt evaporation ponds (the green blue green rectangular features at the southern end of the sea) This image was acquired on December 21, 2022, by the Multi-Spectral Instrument (MSI) aboard the ESA (European Space Agency) Sentinel-2A and -2B satellites Explore this image in Worldview
- Glacier Power Glossary - NASA Earthdata
Glacier Power is a curriculum supplement developed by NASA’s Alaska Satellite Facility Distributed Active Archive Center (ASF DAAC) Glossary of Terms Ablation, Ablation zone Processes (especially melting) by which a glacier loses ice and snow: melting, evaporation, calving, and erosion The area of a glacier where ablation occurs Accumulation, Accumulation zone Process (especially snowfall
- 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 Determining the runoff potential of an area is important data for water resources and agricultural management
