p_model_drivers_vcmax25R Documentation

rsofun p-model driver data (for leaf traits)

Description

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

Usage

p_model_drivers_vcmax25

Format

A tibble of model driver data:

sitename

A character string containing the site names.

forcing

A tibble of forcing climate data for an "average" year, including the following variables:

date

Date in YYYY-MM-DD format (here representative of the day of the year instead of the date of observation).

temp

Air temperature in ^\circC.

vpd

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.

ccov

Cloud coverage in %. This is only used when either PPFD or net radiation are not prescribed.

snow

Snow in mm d^{-1}.

rain

Rain in mm d^{-1}.

fapar

Fraction of photosynthetic active radiation (fAPAR), taking values between 0 and 1.

co2

Annually varying observed atmospheric CO_2, identical across sites.

tmin

Daily minimum air temperature in ^\circC (set equal to temp).

tmax

Daily maximum air temperature in ^\circC.(set equal to temp).

params_siml

A tibble containing 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 days.

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

Longitud of the site location.

lat

Latitude of the site location.

elv

Elevation of the site location, in meters.

whc

A numeric value for the root zone water holding capacity (in mm), used for simulating the soil water balance.
