site flux et télédétection EMMAH

Remote Sensing & Fluxes

Experimental site dedicated to monitor the dynamics of water balance, the radiative balance, energy and CO2 fluxes, as well as biomass production on cultivated surfaces, and the development of remote sensing methods.

Available measurements

Series of measurements of all monitored variables are available during six to twelve years depending on variables:

Vegetation: denisty, canopy height, structure, biomass, phenology, leaf area index (LAI), fraction of absorbed photosynthetically active radiation (fAPAR), canopy cover fraction, water content, nitrogen contant, yield

Soil: moisture, granulometry, composition, nitrogen content

Micrometeorology: radiation, rainfall, flux, temperature
Agricultural practices are also monitored since 12 years. To perform these measurements, we use EMMAH equipments and lab facilities.

Equipement on site

A wide range of remote sensing sensors can be attached to a crane mounted on rails of 120 m in length.

The site is also equipped with an irrigation map and a rolling greenhouse can protect an area of approximately 100 m2.
