Analyzing Water Optical Properties: Hydrolight and Ecolight Exercises

This document details a series of exercises designed to enhance understanding of optical properties in water. Exercise 1 involves inputting measured chlorophyll (Chl(z)) data, while Exercise 2 focuses on inputting inherent optical properties (IOPs) from sensors. Exercises 3 and 4 simulate conditions of increased mineral concentration and optically shallow water, respectively. Additionally, Exercise 5 addresses two hypotheses regarding the impact of inaccurate backscatter data on the Hydrolight curve, emphasizing the principles of "Garbage In, Garbage Out" in data processing.

  1. Lab 9 Hydrolight and Ecolightexercises

  2. Ex. 1: InputtingmeasuredChl(z) data

  3. Ex. 2: inputtingIOPsfrom a, c, and bbsensors

  4. Ex. 3: simulating Case 2 water • Increased mineral concentration increases Rrs in the 550nm wavelengths.

  5. Ex. 4: simulatingopticallyshallow water

  6. Exercise 5Two Hypotheses: Problems causes by wrong backscatter number or “wrong” data inputBackscatter changes don’t appear to help drop the hydrolight curveEditing out the anomalous data line appears to create the desired shape Garbage In, Garbage Out???
