Example data for make_object

Description

Test data for creating climindvis objects using the function make_object. The data contains daily values of tmin,tmax and prec data for 1981-2010.

Usage

data("data type")

Format

A list with 7 elements:

• tmin Daily Minimum temperature data in degrees Celsius. Dimensions depend on data type (see section data types)

• tmax Daily Maximum temperature data in degrees Celsius. Dimensions depend on data type (see section data types)

• prec Daily Precipitation in mm. Dimensions depend on data type (see section data types)

• lon Array of longitudes

• lat Array of latitudes

• time Dimension depends on data_type:

  • data_st/data_grid Array of time steps (time_format=t1d)

  • data_hc_... /data_fc_... Named list containing an array of time steps of class "Date" for each hindcast year /the forecast year (time_format=t2d)

• data_info List <<data_info>> for point data containing type, date_format and data_name as needed by make_object

data types

• data_st Station data for 4 stations. Tmin/tmax/prec are arrays of dimension:
  [stations] x [timesteps]

• data_grid Gridded data for a 3x4 grid. Tmin/tmax/prec are arrays of dimension:
  [longitudes] x [latitudes] x [timesteps

• data_hc_st Hindcast data for 4 stations for a 15 member ensemble. The hindcasts are initialized 1.January for the years 1981-2010 and are issued for the following 214 days. Tmin/tmax/prec are arrays of dimension:
  [stations] x [ensemble members] x [forecast days] x [forecast years]

• data_hc_grid Hindcast data for a 3x4 grid for a 15 member ensemble. The hindcasts are initialized 1.January for the years 1981-2010 and are issued for the following 214 days.Tmin/tmax/prec are arrays of dimension:
  [longitudes] x [latitudes] x [ensemble members] x [forecast days] x [forecast years]

• data fc_st Forecast data for 4 stations for a 15 member ensemble. The forecasts are initialized 1.January 2010 and are issued for the following 214 days. Tmin/tmax/prec are arrays of dimension:
  [stations] x [ensemble members] x [forecast days]

• data_fc_grid Forecast data for 3x4 grid for a 15 member ensemble. The forecasts are initialized 1.January 2010 and are issued for the following 214 days. Tmin/tmax/prec are arrays of dimension:
  [longitudes] x [latitudes] x [ensemble members] x [forecast days]

Examples

## To use the example data you first have to load it using data()
data(data_grid)

# use example data to make climindvis object:
make_object(tmin=data_grid$tmin,dates_tmin=data_grid$time,lon=data_grid$lon,lat=data_grid$lat,data_info=data_grid$data_info)
