The utility of combining optical and thermal images in monitoring agricultural drought in semiarid Mediterranean environments
IM Oroud, RC Balling Jr - Journal of Arid Environments, 2021 - Elsevier
Agricultural drought in a typical semiarid Mediterranean environment is investigated during
the growing seasons of 1997 through 2020 using a combination of optical and thermal
sensors onboard Landsat satellites. The combination of the Normalized Difference
Vegetation Index–Land Surface Temperature (NDVI-LST) space was able to distinguish
between drought and non-drought years. A distinct trapezoidal shape was clearly defined
during non-drought years, reflecting the strong negative correlation between NDVI and LST …
