Example data
example_data.RdData sourced from Oikawa et al."A new coupled biogeochemical modeling approach provides accurate predictions of methane and carbon dioxide fluxes across diverse tidal wetlands." Journal of Geophysical Research: Biogeosciences 129.10 (2024): e2023JG007943. Eddy covariance data are from Ameriflux sites US-Srr, US-Edn, US-LA1, US-PLM, US-Stj See Ameriflux website for site location and information: https://ameriflux.lbl.gov/sites/site-search/ All sites are North American tidal marshes

example_data
A data frame with 7,240 rows and 60 columns:
- site
Ameriflux site ID
- Year
Year
- DOY_disc
Discontinuous day of year (starts over at 1 at the beginning of each year)
- DOY
Day of year (continuously increases over time)
- TA_C
Air temperature (degrees C)
- WTD_cm
Water table depth (cm)
- PAR_umol_m2_day
Average Photosynthetically active radiation (umol m-2 d-1)
- LAI
