Monthly runoff for the Australian continent between 1970-2012. The monthly surface runoff was modelled using a modified version of the two parameter XG monthly runoff model. The model was separately calibrated for each of ten meta-classes of a national ecohydrological environment classification (Pusey et al. 2009) using eMAST monthly precipitation and pan evaporation data and monthly streamflow data for 347 streamflow gauges . Raw monthly runoff grids were then calculated using the calibrated runoff model and input monthly precipitation and pan evaporation grids as provided by eMAST_ANUClimate_mon_prec_v1m0_1970_2012 and eMAST_ANUClimate_mon_evap_v1m0_1970_2012. These runoff grids were made consistent with the ecohydrological classification by resampling at 9 second resolution and reassembling at 0.01 degree resolution. The runoff outputs are in terms of mm per month for each grid cell. These outputs are accumulated downstream in eMAST_ANUClimate_mon_acrf_v1m0_1970_2012. A full description of these runoff grids is in preparation.
Runoff is a major component of the water cycle.
