HELIX: Angström calculated fire risk index for 2061 - 2070 at 1.5 and 2.0 degrees

The High-End cLimate Impacts and eXtremes (HELIX) project have calculated fire danger for the period 2061 to 2070 under two different climate change scenarios based on the Representative Concentration Scenario (RCP) scenarios used within the World Climate Research Programme's (WCRP) Climate Modelling Intercomparion Project phase 5 (CMIP5) using two Fire Indices, the McArthur Forest Fire Danger Index (FFDI), and the Angström Index. This work has been done to assess the change in fire danger at 1.5 degrees compared to 2 degrees Celsius.

This dataset presents those from the Angström calculated fire risk index, utilising Met Office Earth System Model HadGEM2-ES model output at a spatial resolution of 1.875° x 1.25°. The original model data were produced and owned by the Met Office. These results have been saved into gridded netCDF files showing global fire risk. The files represent two experimental runs, one is driven by concentrations following the Representative Concentration Scenario (RCP) 2.6, and the second represents a theoretical Solar Radiation Management scenario using a sulphur dioxide aerosol injection to reduce global mean temperature to 1.5 degrees Celsius. There are 4 ensemble members for each experiment: apdib, apdic, apdid and apdie are the ensemble members for the RCP2.6+SRM run; ajnjm, kaadc, kaaec and kaafc are the ensemble members for the standard RCP2.6 run. A period of 10 years 2061-2070 is chosen for this analysis, and this is compared to a present day period of 2006-2015 (files are labelled according to the data period represented).
