Spatial Heterogeneity of Leaf Area Index (LAI) and Its Temporal Course on Arable Land: Combining Field Measurements, Remote Sensing and Simulation in a Comprehensive Data Analysis Approach (CDAA)
Fig 3
Spatial variability: standard deviations temporal course.
Temporal development of LAI spatial variability expressed as standard deviation (SD) for three separate crops and the overall arable area. (a) Intra-field SD from field measurements only includes fields with at least six measurement points, (b) intra-field SD from 5 m resolution spaceborne remote sensing (rs5m) as boxplots with whiskers ranging to 1.5 times the interquartile range, (c) standard deviations over the test area for the simulation (sim), rs5m, and remote sensing field means (rsfm) derived from rs5m. Each for three separate crops and for the overall arable area of the test region. Y-axes have the same scale and are clipped to save space.
