eLEAF is built on over 20 years of advanced research and we are still developing every day

The interaction of sunlight with the atmosphere, soil and vegetation determine the transport of energy and matter through ecosystems.

 

Following the transport of water illustrates these different processes:

Rainfall and irrigation feed water into an ecosystem or agricultural field. This water enters the soil, where some of it subsequently evaporates, drains off to the groundwater layer or runs off to streams and rivers. Some soil water is taken up by plant and crop roots. Most of this water travels through the plant and transpires through stomata (small openings in leaves), leaving the vegetation in the atmosphere. Water that remains in the plant fuels photosynthesis: a chemical reaction powered by sunlight, that transfers water and carbon dioxide into plant biomass.

 

eLEAF estimates the physical parameters of ecosystems, critical to land, water and crop management. Some key examples:

Evapotranspiration (ET) is the total amount of water that is evaporated from the soil and transpired from plants. In agriculture, it expresses the amount of water lost in the crop production process. Evapotranspiration can be used to determine water use efficiency, and whether crops or vegetation experience water stress.

Biomass production by crops is estimated from the amount of solar radiation received, combined with ambient conditions (availability of water, air temperature, humidity, soil moisture stress) that determine the efficiency of photosynthesis. 

Water use efficiency: the amount of biomass produced given the amount of available water, serves as a proxy for crop health.

Soil moisture content estimates is a key decision parameter for e.g. irrigation planning

 

These quantities are calculated by our models and algorithms, based on inputs from satellites: meteorological data (solar radiation, wind speed, air temperature, relative humidity), surface reflectiveness (albedo), vegetation cover (NDVI). These are determined by weather satellites, and satellites detecting optical, thermal infrared and microwave radiation (radar).
