This video demonstrates how to fit the CO2 Response Curve (A-Ci curve) using the fitting tools. The demonstration includes:
A-Ci Curve Fitting Tools: We'll demonstrate how to download and utilise the A-Ci Curve fitting tools from landflux.org to analyze your data.
Troubleshooting Errors: Learn how to troubleshoot common errors that may arise when using the A-Ci Curve fitting tools.
Data Extraction and Conversion: We'll guide you through extracting key parameters from raw data and converting them into the appropriate units for the fitting tools.
Fitting A-Ci Curves: Master the process of fitting your data to the A-Ci curve model to obtain valuable photosynthetic parameters.
Interpreting CO2 Response Curves: We'll discuss the theoretical basis of CO2 response curves and how to interpret the extracted parameters.
Key Variables: We'll explain the significance of variables like Ca (ambient CO2), Ci (intercellular CO2), and Cc (chloroplastic CO2) in understanding photosynthesis.
Experimental Design and Data Collection: Gain insights into designing effective experiments and determining the optimal number of measurements for reliable A-Ci curves.
