Long pressure series for Barcelona (Spain). daily reconstruction and monthly homogenization

Daily meteorological records for Barcelona, Spain, start unofficially in 17 80. The records are of very good quality, although the metadata are far fro m complete. This study gives the general characteristics of the daily instr umental records, details of the data sources together with the reconstructi on of the daily and monthly pressure series. In the second part of this pap er, a separate time series made up of three (deterministic, periodic and ra ndom) components is analysed, and a methodological approach based on the cu mulative deviation from the mean is then used to homogenize the monthly pre ssure series.
