Beskrivelse

This code presents the main commands used to compute the results on NO2 data from a dense network of low-cost sensors in Camden, London. It presents the use of robust principal component analysis (RPCA) to perform pattern extraction, pollution peaks identification, and signal correction. Bogaert, M., Mouritzen, C., Johnson, M. S. and van Reeuwijk, M. (2024) RPCA-based techniques for pattern extraction, hotspot identification and signal correction using data from a dense network of low-cost NO2 sensors in London.
