The code and data to the article'Can carbon economy explain leaf dynamic seasonality in a tropical seasonal rain forest?'

This README file is associated with the code and data to the article "Can carbon economy explain leaf dynamic seasonality in a tropical seasonal rain forest?" Description on the code and data which involved in the study. 1. The Forest-CEW model This model is a self-developed model by Jiye Zeng and Zheng-Hong Tan which first finished in 2018 and a updated version in 2022. The model is portable. Users double click the fcew.exe file, user-interface will be jump out. Users could easily use the model follow the user interfact. For advance user, the source code is provided which written C++. 2. The reproducing of figure 2 In Figure 2, the leaf area index was estimated by couple of sensors which placed both above the canopy and below the canopy according to the Beer-Lambert Law. The matlab code for walsh seasonality index was also provided. The solar zenith angle is important in apply Beer-Lambert law in forest canopy. The funtion SolarZenith is used to accomplish this. there is a data save in WSIdata.csv. The meanning of each column are: column 1: time column 2: latent heat flux (w m-2) column 3: sensible heat flux (w m-2) column 4: friction velocity (m s-1) column 5: air density (kg m-3) column 6: downward shortwave radiation (w m-2) column 7: upward shortwave radiation (w m-2) column 8: downward longwave radiation (w m-2) column 9: upward longwave radiation (w m-2) column 10: canopy temperature measured by Apogee sensor (℃) column 11: surface temperature at forest floor measured by Apogee sensor (℃) column 12: soil temperature at 5 cm depth (℃) column 13: soil temperature at 20 cm depth (℃) column 14: soil temperature at 40 cm depth (℃) column 15: air temperature at level 4 (℃) column 16: air temperature at level 5 (℃) column 17: air temperature at level 6 (℃) column 18: air temperature at level 7 (℃) column 19: wind speed at level 4 (m s-1) column 20: wind speed at level 5 (m s-1) column 21: wind speed at level 6 (m s-1) column 22: wind speed at level 7 (m s-1) column 23: water vapor pressure at level 4 (kPa) ...
