 In order to bridge the gap between the end user's and the climate modeller's communities, it is necessary to achieve a consensus so that the requirements for CII computation are met by the climate model outputs. Ideally, this should entail the availability of some variables used as input for CIIs at the sub-daily scale when necessary (either 3 or 6-h should suffice to approximate local standard times). The use of inadequate data for CII computation may lead to problems seriously impairing the validity of the results in impact studies. This issue is analysed in detail for the particular case of the Canadian Fire Weather Index (FWI) by [http://link.springer.com/article/10.1007%2Fs10584-012-0667-2 Herrera et al. (2013)], which highlights the problems related to the use of daily averaged data for FWI calculation.
 
-As an alternative, the use of proxy variables for the construction of CIIs could be also explored, although it is important to remark that this is always a sub-optimal solution that should be only considered when the required variables are by no means available. Furthermore, the use of adequate proxies always requires a prior assessment involving the availability of at least some control data. An example of the use of proxies for CII computation and their use for future climate impact assessment is given in the regional projections of fire danger for Europe by [http://www.meteo.unican.es/en/node/73188 Bedia et al (in press)], using the FWI system.
