Temporal interpolation for "one-point" gaps in hourly temperature

Description of Method

Locate a single missing value

Check if data available immediately before and after the interval

If available generates first estimate from linear interpolation

Checks for the Max and Min temperature for the missing value from the measurements registered in the hour afterwards

Provide an estimate T1 for the missing value as the average of 0.5*(MaxT + MinT)

Update the correcte dvalue following the rules below:

If an existing corrected value exists and it was generated by HQC

do not update, leave correction from HQC

If an existing corrected value exists and not from HQC:

check if existing value: MaxT >= existing corrected >= MinT

if FALSE update corrected with T1

If no corrected value exists:

update corrected value with T1
