Artemis provides a simple runoff production model designed to be comparable with the runoff-production models typically embedded within climate models.

It is driven with precipitation, radiation, temperature, humidity and wind speed on a daily time step and calculates canopy interception, evaporation, snowmelt, infiltration, and runoff. It uses a Rutter–Gash canopy formulation (Gash, 1979) to represent interception, together with Penman–Monteith evaporation calculated using available radiation data (Monteith, 1965). Soil moisture is accounted for using a two-layer model with saturation-excess runoff computed using a generalized TOPMODEL (Clark and Gedney, 2008). The snowpack is represented using a temperature-based model of accumulation and melt (Moore et al., 1999, Hock, 2003, Beven, 2011). Snow accumulates when precipitation falls while temperature is below a threshold temperature. When temperature is above a threshold for melt, melting occurs at a rate proportional to the difference between the current temperature and the melting temperature. This conceptual model is widely used (Hock, 2003, Zhang et al., 2006, Rango and Martinec, 1995, Beven, 2011) and gives performance comparable with that of more parameter rich energy balance models, despite their greater complexity (Parajka et al., 2010).

The surface layer component of Artemis comprises canopy interception, evaporation, and snowmelt.

The sub-surface component of Artemis comprises infiltration and runoff.
