summary:
The Pixel Quality (PQ) product is an assessment of whether an image pixel represents an un-obscured unsaturated observation of the Earth's surface and whether the pixel is represented in each spectral band. The PQ product allows users to produce masks which can be used to exclude affected pixels from which don't meet their quality criteria from further analysis. The capacity to automatically exclude such pixels from analysis is essential for emerging multi-temporal analysis techniques that make use of every quality assured pixel within a time series of observations. The PQ-STATS is a countof how many times a pixel contains a clear observation of the surface (land or sea). The count of clean observations provides users with an understanding of how many observations are available for analysis at a particular location for a particular period of time. PQ-STATS is available as a per year summary and as a 'whole of archive' summary (1987 to present).
