Measuring H2O and CO2 fluxes at field scales with scintillometry: Part II - Validation and application of 1-min flux estimates

► 1-min fluxes can be accurately determined with the proposed methodology. ► On 1-min time scales, the time lag between flux and radiation must be considered. ► Storage changes play an important role in the energy balance for 1-min intervals. ► 1-min fluxes are very relevant for studying atmosphere-vegetation-soil interactions. ► A wheat vegetation can change its canopy resistance within several minutes.
