NWFP_Daily_Data_QC_MV_Adjusted_Summary_Report_2012-01-01-2023-12-31

This report includes tables and graphics of summary statistics of the daily means data set ‘NWFP_Daily_Means_QCadjusted_MissValsadjusted_2012-01-01_2023-12-31.csv’ published on the Rothamsted Research data repository [https://data.rothamsted.ac.uk/dataset/qc-and-missing-values-adjusted].
The published data set was calculated from yearly csv files (2012‐2023) of 15-minute time steps for water flow, various water quality parameters, soil temperature, soil moisture and precipitation that were downloaded from the North Wyke Farm Platform Data Portal [https://nwfp.rothamsted.ac.uk/].
The 15-minute data were first screened based on the Quality Control (QC) flag that was assigned to the value at each time step during the QC process. Values that did not have ‘Good’, ‘Acceptable’ and ‘Outlier’ QC flags were set to ‘NA’ to represent missing value. In addition, since the number of within day missing values impacts the reliability of the statistic, means were set to ‘NA’ where the threshold limit for the acceptable number of daily missing values for each variable was exceeded.
