Improving stability of NDVI data for NOAA environmental satellite

摘要

Empirical distribution functions were applied for improving stability of NDVI data for NOAA environmental satellites This paper investigates NDVI stability in the NOAA/NESDIS Global Vegetation Index (GVI) data set during 1982-2003, in the period, which includes five NOAA series satellites. Degradation of NDVI over time and NDVI's shifts between the satellites were estimated for geographical location in China. The method of matching empirical distribution functions improves the time relative stability of NDVI data for all satellites, especially NOAA-9, -11 and -14.
