rsofun P-model driver data (for leaf traits)

Small tests dataset to validate if compiled code and optimization routines can run for leaf traits data

p_model_drivers_vcmax25

Format

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 variables:

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.

spinup

A logical value indicating whether this simulation does spin-up.

spinupyears

Number of spin-up years.

recycle

Length of standard recycling period, in years.

outdt

An integer indicating the output periodicity.

ltre

A logical value, TRUE if evergreen tree.

ltne

A logical value, TRUE if evergreen tree and N-fixing.

ltrd

A logical value, TRUE if deciduous tree.

ltnd

A logical value, TRUE if deciduous tree and N-fixing.

lgr3

A logical value, TRUE if grass with C3 photosynthetic pathway.

lgn3

A logical value, TRUE if grass with C3 photosynthetic pathway and N-fixing.

lgr4

A logical value, TRUE if grass with C4 photosynthetic pathway.

site_info

A tibble containing site meta information.

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)
