Guidelines for Manual QC of MAAP (Multiangle Absorption Photometer) data

These guidelines cover manual Quality Control (QC) of MAAP (Multiangle Absorption Photometer) data.

The manual data QC is performed on the level 0 data, i.e. the raw data output, augmented with essential discovery and use metadata, and brought to a standardised data format. For the purpose of manual QC, temporary level 1 and 2 data versions are produced from the initial level 0 version. When performing manual QC for a given time period of data, e.g. a year for an annual submission of data, the parameters contained in the level 0, 1, or 2 data listed below are to be plotted as time series, and visually inspected in intervals of maximum 2 weeks at a time.
