    Data supporting 'Non-stationary control of the NAO on European rainfall and its implications for water resource management'
    (Cranfield University, 2023-02-10 17:32) Rust, Will; Holman, Ian; Corstanje, Ronald; Cuthbert, Mark; P. Bloomfield, John
    10-year window rolling correlation between NAOI and GPCC gridded rainfall data for Western Europe. Grid cells between -13-20° Longitude and 35-70° Latitude were used to represent Western Europe.

    1- 157 x 136 matrix containing calculated drought series for each 136 GWL records over 157 years. NAs present where no GWL record present. Drought threshold method used after Peters et al, 2003.2 - 139 x 767 matrix containing calculated streamflow drought series for 767 streamflow gauges over 139 years. Value represents Boolean of whether a drought occurred in calendar year.3 - 201 x 157 x 136 array of cross-wavelet transform pval results between 136 groundwater level records over 157 years at 201 frequency intervals. NA values present where no values recorded in original GWL series.4 - 201 x 157 x 767 array of cross-wavelet transform pval results between 767 streamflow records over 157 years at 201 frequency intervals. NA values present where no values recorded in original GWL series.5 - 201 x 157 x 136 array of cross-wavelet transform power results between 136 groundwater level records over 157 years at 201 frequency intervals. NA values present where no values recorded in original GWL series.6 - 5 - 201 x 157 x 767 array of cross-wavelet transform power results between 767 streamflow records over 157 years at 201 frequency intervals. NA values present where no values recorded in original GWL series.7 - 157 x 136 matrix containing phase difference values between the NAO and 136 groundwater level records over 157 year time period. Phase difference for the 7.5 year periodicity.8 - 157 x 767 matrix containing phase difference values between the NAO and 767 streamflow records over 157 year time period. Phase difference for the 7.5 year periodicity.
