- 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

- MODIS Terra Net Evapotranspiration Yearly L4 Global 500m . . . - Earthdata
The MOD16A3 Version 6 data product was decommissioned due to unexpected errors in the input data Users are encouraged to use the MOD16A3GF Version 6 1 data product The MOD16A3 Version 6 Evapotranspiration Latent Heat Flux product is a yearly composite dataset produced at 500 meter (m) pixel resolution The algorithm is based on the logic of the Penman-Monteith equation, which includes inputs
- Glacier Power: What is Glacier Anatomy? - NASA Earthdata
Anatomy of a Glacier Definitions 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
- ECOSTRESS Tiled Evapotranspiration Instantaneous and Daytime L3 Global . . .
The ECOSTRESS Tiled Evapotranspiration Instantaneous and Daytime L3 Global 70 m (ECO_L3T_JET) Version 2 data product provides instantaneous canopy transpiration, leaf surface evaporation, and soil moisture evaporation using the Priestley-Taylor formula This data product is tiled using a modified version of the Military Grid Reference System (MGRS), which divides Universal Transverse Mercator
- ECOSTRESS: NASAs Next-Generation Mission to Measure . . . - Earthdata
Based on thermal radiometer measurements, ECOSTRESS produces multiple data products at 70 m spatial resolution: land surface temperature and emissivity (L2_LSTE), evapotranspiration (L3_ET; partitioned into canopy transpiration, soil evaporation, and interception evaporation), water use efficiency (L4_WUE), and the Evaporative Stress Index (L4
- 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
- MODIS Terra Net Evapotranspiration 8-Day L4 Global 500m SIN Grid V061
Description The MOD16A2 Version 6 1 Evapotranspiration Latent Heat Flux product is an 8-day composite dataset produced at 500 meter (m) pixel resolution The algorithm used for the MOD16 data product collection is based on the logic of the Penman-Monteith equation, which includes inputs of daily meteorological reanalysis data along with Moderate Resolution Imaging Spectroradiometer (MODIS
