Small dataset representing the driver to run the P-model at the FR-Pue site.
It can also be used together with daily GPP flux time series data from CH-LAE
(p_model_validation) to optimize model parameters.
To optimize model parameters to leaf traits data use the datasets p_model_drivers_vcmax25 and p_model_validation_vcmax25.
p_model_driversFormat
A tibble of driver data:
- sitename
A character string containing the site name.
- forcing
A tibble of a time series of forcing climate data, including the following data:
- date
Date of the observation in YYYY-MM-DD format.
- temp
Daytime average air temperature in \(^\circ\)C.
- vpd
Daytime average vapour pressure deficit in Pa.
- ppfd
Photosynthetic photon flux density (PPFD) in mol m\(^{-2}\) s\(^{-1}\). If all values are NA, it indicates that PPFD should be calculated by the SPLASH model.
- netrad
Net radiation in W m\(^{-2}\). This is currently ignored as a model forcing.
- patm
Atmospheric pressure in Pa.
- snow
Snow in water equivalents mm s\(^{-1}\).
- rain
Rain as precipitation in liquid form in mm s\(^{-1}\).
- tmin
Daily minimum air temperature in \(^\circ\)C.
- tmax
Daily maximum air temperature in \(^\circ\)C.
- fapar
Fraction of photosynthetic active radiation (fAPAR), taking values between 0 and 1.
- co2
Atmospheric CO\(_2\) concentration.
- ccov
Cloud coverage in %. This is only used when either PPFD or net radiation are not prescribed.
- params_siml
A tibble of simulation parameters, including the following data:
- spinup
A logical value indicating whether this simulation does spin-up.
- spinupyears
Number of spin-up years.
- recycle
Number of first N years of forcing data.frame that are recycled for spin-up.
- outdt
An integer indicating the output periodicity.
- ltre
A logical value,
TRUEif evergreen tree.- ltne
A logical value,
TRUEif evergreen tree and N-fixing.- ltrd
A logical value,
TRUEif deciduous tree.- ltnd
A logical value,
TRUEif deciduous tree and N-fixing.- lgr3
A logical value,
TRUEif grass with C3 photosynthetic pathway.- lgn3
A logical value,
TRUEif grass with C3 photosynthetic pathway and N-fixing.- lgr4
A logical value,
TRUEif grass with C4 photosynthetic pathway.
- site_info
A tibble containing site meta information. This data structure can be freely used for documenting the dataset, but must include at least the following data:
- lon
Longitude of the site location in degrees east.
- lat
Latitude of the site location in degrees north.
- elv
Elevation of the site location, in meters above sea level.
- whc
A numeric value for the rooting zone water holding capacity (in mm)
