Conclusions

Remotely sensed satellite optical and thermal infrared can be synergistically used to estimate surface agro-meteorological properties. Optical data can be used to estimate land surface albedo by integrating narrow-band directional spectral reflectances. Thermal IR data from various satellites appear as valuable tool for vegetation growth and conditions assessment by retrieval of land surface temperature and estimation of evapotranspiration following various modeling approaches. Optical data in the form of spectral indices are found to be related to solar radiation absorbed by vegetation canopies and this is useful for assessing regional vegetation potential productivity.
