Add modelling parameters to a model object
add_params(model, lat = NULL, lon = NULL, height = NULL,
duration = NULL, run_period = NULL, start_day = NULL,
start_hour = NULL, daily_hours = NULL, direction = NULL,
met_type = NULL, vert_motion = NULL, model_height = NULL)a SplitR modeling object.
the starting latitude (in decimal degrees) for the model run(s).
the starting longitude (in decimal degrees) for the model run(s).
the starting height (in meters above ground level) for the model run(s).
the duration of one or several
model runs (either forward or
backward) in hours.
the extended period (i.e., days,
years) when the model will initialize and run. This
can take the form of a single-length vector for a
day ("YYYY-MM-DD") or year (YYYY), or,
a vector of length 2 to specify the range of days or
years.
is specific to a dispersion model
and it refers to the day that the model will
initialize and run. This should take the form of a
single-length vector for a day ("YYYY-MM-DD").
is specific to a dispersion model
and it should indicate which hour in the
start_day that modeling will begin. Provide
this as an integer (from 0 to 23).
are specific to a trajectory
model and should consist of a single daily hour as
an integer (from 0 to 23), or, a
vector of several daily hours represented as
integers.
an option to select whether to
conduct the model in the forward or
backward directions.
an option to select meteorological
data files. The options are gdas1 (Global
Data Assimilation System 1-degree resolution data),
reanalysis (NCAR/NCEP global reanalysis
data), and narr (North American Regional
Reanalysis).
a numbered option to
select the method used to simulation vertical
motion. The methods are: 0 (input model
data), 1 (isobaric), 2 (isentropic),
3 (constant density), 4 (isosigma),
5 (from divergence), 6 (remap MSL to
AGL), 7 (average data), and 8 (damped
magnitude).
the upper limit of the model domain in meters.
