Summary:

Total Respiration Calculation

The total respiration (Rt) is calculated in proportion to the maximum carboxylation rate (Vc,max) as:

Rt = 0.015 * Vc,max

The daily respiration (Rtd) is then calculated based on the daytime and nighttime durations, and the temperature response functions for respiration:

Rtd = Rt * (Dday + Dnight * fr(Tnight)/fr(Tday))

Where:
- Dday and Dnight are the daytime and nighttime durations in seconds
- fr(Tnight) and fr(Tday) are the temperature response functions for nighttime and daytime respiration

The temperature response functions are further detailed in Appendix B of the referenced Ali et al. (2016) paper.
