NDVI relationship to monthly evaporation [PDF]

Geophysical Research Letters, 1998
Normalized difference vegetation indices (NDVI), calculated from Landsat‐MSS images, were correlated with monthly total precipitation and estimates of monthly evaporation in a prairie environment. The highest value of the correlation coefficient (r=.80) was obtained between the monthly mean NDVI and estimated evaporation of the preceding month.

Study on Spatial Scale Transformation Method of MODIS NDVI and NOAA NDVI in Inner Mongolia Grassland [PDF]

, 2011
Based on MODIS NDVI and NOAA NDVI datum, covering the primary grassland types of Inner Mongolian in growing seasons from 2000 to 2003, this paper analyzes annual variation rule of the relationship between MODIS NDVI and NOAA NDVI datum. We use the theory of statistics to discuss the spatial scaling methods between different resolutions images of remote
