Introduction
Solar radiation drives almost every dynamic process on the Earth’s surface and above, from ocean current circulation to the
weather, and life itself. Precise long-term measurements of the radiation budget at the surface are fundamental to understanding
the Earth’s climate system. Rising fossil fuel costs and the need to reduce Carbon footprints has produced a rapid growth in the
market for ‘green’ energy, in which the fastest growing sector is solar power.
