Estimates vegetation health (condition) based on combination of vegetation greenness (Normalized
Difference Vegetation Index, NDVI) and temperature (Brightness Temperature,
BT).
- VCI – TCI - Vegetation & Temperature Condition Indices:
Estimate moisture and thermal conditions, respectively, based on NDVI and BT.
- SMN – Smoothed NDVI:
NDVI without high frequency noise.
- SMT – Smoothed BT:
BT without high frequency noise.
- Fire Risk Index:
Index showing if conditions of vegetation are suitable for fire development.
