Multi-scale observation matrix over heterogeneous land surfaces for verifying remote sensing results

From fitting coefficients a, differences of secelected paired towers were 6~27% and most of determination coefficients were closed to 1. From σ, the differences were less than 10.0W/m² for sensible heat flux and less than 5μmmol/m²/s for CO₂ flux while 29.4~44.1W/m² for latent heat flux which indicated the big differences of evaporation among the stations. All these data will support high quality datasets for the verification and validation of the airborne and satellite remote sensing results.
