ESCIMO.spread is a spreadsheet-based point energy balance model to simulate energy, mass balance and melt rates of a snow surface.

The model makes use of hourly recordings of temperature, precipitation, wind speed, relative humidity, global and longwave radiation.

The effect of potential climate change on the seasonal evolution of snow-cover may be estimated by modifying the time series of observed temperature and precipitation, using adjustable parameters.

Model output is graphically visualized in hourly and daily diagrams.

The results compare well with weekly measured snow water equivalent (SWE).

The model is portable and adjustable, and runs particularly fast: hourly calculation of a one winter season is instantaneous on a standard computer.
