Comparison of the NDVI, ARVI and AFRI vegetation index, along with their relations with the AOD using SPOT 4 Vegetation data

摘要

This paper explores two such indexes- the Aerosol Free Vegetation Index (AFRI) and the Atmospherically Resistant Vegetation Index ARVI). Comparisons were made with the NDVI normalized vegetation index) to see if they indeed performed better. In general, the results showed that the AFRI and ARVI (with gamma=1) did indeed perform better than their NDVI counterpart study with the related channels were employed.
