WebThe Apogee chlorophyll concentration meter is calibrated to measure chlorophyll concentration in leaves with units of µmol of chlorophyll per m 2. This eliminates problems with relative indices of chlorophyll concentration. For reference and comparison purposes, the Apogee meter also outputs relative units (CCI or SPAD), if desired. WebBy utilizing an empirical chlorophyll model created by Mishra and Mishra (2012), pre-processed Sentinel-2 images were used to derive the normalized differential chloro-phyll index (NDCI).
