The North Wyke Farm Platform: Quality Control System (Data version 3; released on 01-12-2018)

The North Wyke Farm Platform (NWFP) was established in 2010 to study and improve grassland livestock production at the farm-scale. The NWFP uses a combination of environmental sensors, routine field and lab-based measurements, and detailed management records to monitor livestock and crop production, emissions to water, emissions to air, soil health, and biodiversity. The rich NWFP datasets help researchers to evaluate the effectiveness of different grassland (and arable) farming systems, which in turn, contributes to the development of sustainable, resilient and net zero land management strategies. This document serves as a user guide to the quality control (QC) system of the water run-off, water chemistry, soil moisture and meteorological data produced at a 15-minute temporal resolution on the North Wyke Farm Platform (NWFP). The guide gives limits and thresholds for the instrumentation, and the QC flags applied to each data point. Also included are information on the QC process for the latest data version and changes since the previous version. This document is associated with other dedicated user guides that detail the collection of other dataset types produced on the NWFP.
