Much of our understanding of ecosystem spectral diversity (diversity estimated from visible to shortwave infrared imaging spectroscopy reflectance data) comes from data that are collected at a single time point during the course of a year. This perspective limits how we understand changes in diversity that can be observed from airborne or space-borne remote sensing at seasonal or subseasonal scales, particularly in systems that have rapid phenological changes over the course of the year. I will discuss the implications of observation timing and interval for our understanding of spectral diversity across time and space.
