“…The decrease observed during the third measuring round, however, could be an artifact caused by seasonal variations in the near-infrared (NIR) and red reflectance of birch forests (Nilson et al 2012). CCI is a simple measure of the ratio of NIR (931nm, which approximates leaf structure) to red (653nm, which is within the absorbance range of chlorophyll) transmittance, and leaf aging related changes in e.g.…”

“…Birch leaf biochemistry is known to exhibit seasonal changes during the growing season (Riipi et al 2002, Laitinen et al 2002) and seasonal changes have been observed in the reflectance of boreal forests (Nilson et al 2012). However, seasonal changes in chlorophyll content that are known to occur for other species (Croft et al 2017) have not been monitored in birch, except for chlorophyll degradation during autumnal leaf senescence (Mattila et al 2018).…”

“…El patrón de la Figura 2, de evolución temporal de reflectancias normalizadas o no, es similar al que se observa para el caso de bosques (Nilson et al, 2012) y vegetación herbácea (Hunt y Williams, 2006;Chen et al, 2009). …”

“…Este patrón es similar al que se observó en experimentos de floración (número de flores) en vegetación herbácea, en donde con el incremento de la floración, las bandas del R e IRC crecen simultáneamente (Hunt y Williams, 2006;Chen et al, 2009). En bosques, Nilson et al (2012) mostraron que la banda del R se incrementa y disminuye durante la ocurrencia de la floración, en forma similar a lo que sucede con la floración en vegetación herbácea, pero la banda del IRC, con ruido, muestra un patrón no sincronizado en tiempo, aparentemente, con la banda del R. Algo similar se observó en vegetación herbácea (Hunt y Williams, 2006).…”
