Brief communication: An ice surface melt scheme including the diurnal cycle of solar radiation
<p>We propose a surface melt scheme for glaciated land surfaces, which only requires monthly mean short-wave radiation and temperature as inputs, yet implicitly accounts for the diurnal cycle of short-wave radiation. The scheme is deduced from the energy balance of a daily melt period, which i...

| Summary: | <p>We propose a surface melt scheme for glaciated
land surfaces, which only requires monthly mean short-wave radiation and
temperature as inputs, yet implicitly accounts for the diurnal cycle of
short-wave radiation. The scheme is deduced from the energy balance of a
daily melt period, which is defined by a minimum solar elevation angle. The
scheme yields a better spatial representation of melting than common
empirical schemes when applied to the Greenland Ice Sheet, using a 1948–2016
regional climate and snowpack simulation as a reference. The scheme is
physically constrained and can be adapted to other regions or time periods.</p> |
