North-south storm track index reconstruction for western Europe from Pedrido Bog, Galicia, Spain

To create the storm track index, the above described storminess record from Spain was subtracted from a storminess record from Scotland, derived by averaging the results of two storminess reconstructions from the Outer Hebrides, Scotland (Orme et al., 2016). Each record was sampled to the same 20 year temporal resolution and standardised prior to this.
