Data analysis method:
Light absorption of filter extraction is measured for 250 - 750 nm wavelength. Absorption at 700 nm is set as the baseline. See Hecobian et al. (2010, ACP) for the detail.
Quantification method:
Light absorption is measured as an arbitrary unit. It is converted into absorbance (Mm-1) following the equation in Hecobian et al., (2010, ACP).
Calibration method:
Calibration drift estimate:
No estimate
Calibration schedule:
Uncertainty estimation method:
Measure the extracted sample multiple times and take the average.
