text: The ClimPACT extreme weather indices, HCVI and JULES run-off simulations were all performed 
  using outputs from the higher-resolution HadGEM3 projections described in §2a. However, there 
  were some differences in how these data were applied, with different approaches to the treatment 
  of systematic biases in the climate model output. For the ClimPACT analysis, it was considered 
  important to assess changes in the raw climate model output, because this directly represents 
  the behaviour of the model itself. The main focus was on the changes relative to the present- 
  day baseline climate, deﬁned as 1981–2010, with absolute values in either the baseline or the 
  GWLs of 1.5°C and 2°C being only of secondary interest. For the HCVI and JULES run-off 
  analyses, however, it was considered important to correct for systematic biases in the climate 
  model output, because these can lead to unrealistic representations of the key quantities in the 
  present-day simulation [35]. A bias-correction methodology was, therefore, applied for these two 
  parts of the analysis, whereby the model output was adjusted to make it consistent with an 
  observed climatology [36]. We used a multi-segment statistical bias-correction methodology for 
  precipitation [37], and a modiﬁcation of this for other variables [37].
