Abstract

ClearfLo (Clean Air for London) Project was a collaborative scientific project involving several academic institutions in the UK, which aimed to set up air pollution monitoring sites alongside meteorological measurements to investigate boundary layer pollution across London.

This dataset contains NAME airmass footprint images and measurements of ammonia, carbon dioxide, methane, carbon monoxide, nitrogen, nitrogen oxide and ozone at the BT-Tower, London.
