HS2 environmental dataset

Dataset Overview This dataset provides standardised hourly air-quality and noise measurements collected around High Speed Two (HS2) construction sites. The original data were published as heterogeneous monthly Excel workbooks by Buckinghamshire Council, Birmingham City Council, and the London Borough of Camden. These files were systematically classified, extracted, standardised, aggregated by monitor, and audited to produce consistent machine-readable time series. The published dataset contains 166 monitor-level datasets, 652,939 physical records, and 1,359,818 finite environmental readings. It covers PM₁₀ air-quality measurements and three noise measurements: LpAeq,T, LpA90,T, and LpAF,max.
