- •
The role of tree canopy cover on land surface albedo (LSA) and land surface temperature (LST) was analysed.
- •
A modelling procedure using the SGB algorithm and Landsat 5-TM data was developed to estimate canopy cover at pixel level.
- •
Significant relationship was found between tree canopy cover percentage and mean annual LSA and LST.
- •
A potential tree canopy cover regression in a Mediterranean semi-arid ecosystem may produce significant changes in LSA and LST.
