“…RMSE of Chl content prediction by CI red edge was 38 mg m -2 in the range of Chl content 22-880 mg m -2 by (details in Gitelson et al, 2003Gitelson et al, , 2006Ciganda et al, 2009). The stand reflectance measurements and ground measurements were not always concurrent and, since LAI and leaf Chl content changed gradually, spline interpolations were taken between destructive LAI sampling dates for each field in each year using Matlab (V. 7.9.0.529, The MathWorks, Massachusetts, USA) (Nguy-Robertson et al, 2012).…”
