Nov 21, 2025 · 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 …

Nov 21, 2025 · View glossary terms related to the Glacier Power curriculum supplement developed by NASA’s Alaska Satellite Facility Distributed Active Archive Center (ASF DAAC).

Nov 14, 2025 · 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. …

Nov 21, 2025 · 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 …

Nov 21, 2025 · 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 …

The monthly temporal and one-degree spatial resolution of the product can be used to examining climate variability at these scales. Oceanic evaporation contributes to the net fresh water input to the …

Concept ID C2804749057-ORNL_CLOUD Data State COMPLETE Number of Files/Granules 4 Processing Level 4 Published 1994-07-24 Updated 2023-11-19 Science Keywords Evaporation , …

Dec 28, 2020 · 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 …

This dataset provides daily-averaged ocean and sea-ice surface heat fluxes on the native Lat-Lon-Cap 90 (LLC90) model grid from the ECCO Version 4 Release 4 (V4r4) ocean and sea-ice state estimate. …

Mass fluxes from evaporation, precipitation, and runoff (EXFempmr) happen at the same temperature as the ocean surface temperature. Consequently, EmPmR does not change ocean surface …
