What NDWI are used? NDWI from Gao (1996) based on NIR and SWIR or NDWI from McFeeters (1996) based on Green and NIR.
I think that NDVI (Rouse et al. 1973) and MNDWI (Modified Normalized Difference Water Index) from Xu (2006) also presented very good the changes in the temporal analysis.
Why presented the value of NDWI only average? With minimal and maximal value we can observed trends in temporal analysis.
