As was observed for the leaf production period, the
individual yearly NDVI–LAI relations during the leaf
senescence period had good R2 values (R2 of 1.00, 0.95,
and 0.95 for years 1996, 1997, and 2000, respectively).
Again, pooling the data over the three years gave an R2 of
only 0.17. By correcting for the background NDVI before
pooling, the relation improved considerably:
