The Role of Land in Solar Energy Absorption

You’ll be surprised by how much solar energy is absorbed by the land. The land surface temperature plays a crucial role in this absorption process.

When solar radiation reaches the Earth’s surface, it is either reflected or absorbed. Around 50% of the solar radiation is absorbed by the land, while the rest is reflected back into the atmosphere or absorbed by the oceans.

The absorption of solar energy by the land leads to an increase in land surface temperature. This increase in temperature has various effects, such as influencing weather patterns, affecting plant growth, and contributing to the formation of urban heat islands.
