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}. If all values are NA,
it indicates that net radiation should be calculated by the SPLASH
model.
- 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.
