Description

For the input official wind speed data with locations, first find their quantiles from 0.01 to 1 with step interval of 0.01 (100 in total), then for quantiles at each level using ordinary kriging to interpolate estimated quantiles at other locations.

kriging_quantile_true(

  split.season = TRUE
)

Arguments

official.windspeed

a data.frame of official/reference wind speed observations, each column represents an individual station, each row represents a timestamp.

datetime.sequence

the date time stamps/sequence of the data official.windspeed, should indicate the row names of official.windspeed.

official.longitude

a numeric vector, contains longitude information of official stations, should relate to the column names (station IDs) of official.windspeed.

official.latitude

a numeric vector, contains latitude information of official stations, should relate to the column names (station IDs) of official.windspeed.

split.season

a logical, if TRUE we perform the spatial interpolation by six different periods (winter/summer/transition season, day/night time) respectively; The six periods are determined by months and hours in a day: winter - 12,1,2,3; summer - 6,7,8,9; trans (transition periods between winter and summer) - 4,5,10,11; day - 7:00~18:00; night - 19:00~6:00; 6 periods: winter_night, winter_day, trans_night, trans_day, summer_night, summer_day.

Value

a large list that contains the estimated quantiles at different locations of each period. It has 6 sublists, each one represent a certain period; Each sublist includes estimated quantiles from 0.01 to 1 at thousands of new locations.
