fill_gap: Correlation with other stations

In MariekeDirk/Dimming-Brightening: Dimming and Brightening analysis for global radiation

Description

calculates the correlation coefficient from the series with gaps to all the other series and computes a buffer with a 500km radius. At least 5 available observations per month for all the data is recommended, otherwise the normalization of the data and correlation coef. can give a wrong impression.

Usage

fill_gap(
  meta,
  series,
  full_data_series,
  missing_date,
  buffer_dist = 500,
  n.months = 5,
  n.stations = 5
)

Arguments

meta	metadata with lat lon from all the stations
series	series with missing data
full_data_series	full data series which will be used to fill the gap
missing_date	missing month from the series
buffer_dist	minimum distance to the filling stations in km. Returning 1 if the full_data_series stations falls within the buffer zone.
n.months	minimum number of months with needed to compute correlation coef.
n.stations	maximum number of reference stations from which the median is calculated
