Table 1.
Comparison of retrieval algorithms for chlorophyll a in Case 1 and Case
2 waters. Rl is the reflectance value for a respective
wavelength, and RLH is
reflectance line height above baseline (see Figure 26), a w
=water absorption (m
-1
), b b
= backscatter (m
-1
), and int is the 10 nm bandwidth integral.
