Land cover classification at 30 m resolution for the Colombian Amazon for the year 2016.
New maps of land cover classes for the Colombian Amazon were derived from changes in surface reflectance.
Relationship between the quantum yields of fluorescence (Ft) and photosystem II (Fv/Fm) sampled Picea glauca needles in Alaska (A) and Abies grandis needles in Idaho (B). Modeled (A) and observed (B) irradiance is indicated by the coloration of points; grey points in individual sampling period panels show observations from all periods for reference. Plots of sampling periods aligned with the timing of satellite overpasses are outlined in green (A) and blue (B) boxes, respectively.
In situ measurements of needle-level chlorophyll fluorescence and other irradiance products are now available.
