clean_wunderground: Clean and interpolate wunderground data

In MariekeDirk/uhi_max: Maximum Urban Heat island

Description

Filters out non-realistic low values downloaded using 'download_time_seq', creates UTC timestamps from which a 10min sequence is created. The following filters are applied:

• Temperatures lower than -40 are unrealistic in the Netherlands and are excluded (set to NA)

• Similarly temperatures above 45 are also excluded (set to NA)

• In case there are more than 8 identical measurements in a row the value is set to NA

If the gap between the measurements is more than 1 hour values are not interpolated.

  datafile = "C:/Users/marie/OneDrive/Documenten/uhi_max/inst/Wunderground/IUTRECHT23/daydata_rbind_2009-01-01_until_2018-11-27.txt",
  fname = "C:/Users/marie/OneDrive/Documenten/uhi_max/inst/Wunderground/Filtered/IUTRECHT23_filtered.rds")
