Monthly mean pressure reconstructions for Europe (back to 1780) and North America (to 1958)
Monthly grid-point pressure data are reconstructed from station records of air temperature, precipitation and pressure for Europe, back to 1780, and North America, back to 1858. The reconstructions are based on a principal components regression technique which relates surface pressure patterns to those of the temperature, precipitation and station pressure data. The relationships are derived over a calibration period and the results are tested with independent data from another period. To illustrate the results examples are given of pressure anomalies over Europe during 1816 (the ''year without a summer''), anomalies over both Europe and North America for January and November 1862 (months with particularly strong anomalies), and anomalies over North America during 1884 (the year after Krakatau). The reconstructions are compared with other monthly mean pressure maps produced by Lamb and Johnson (1966) for Europe for 1780 to 1872 and for North America for 1858 to 1898, and by Kington (1980) for Europe for 1781 to 1785. Both of these map series show systematic biases relative to the present reconstructions. The reconstructed data are available on a magnetic tape.
