Solar radiation management


Solar radiation management includes techniques that seek to reflect the sunlight reducing at the same time the global warming. These techniques have a go at reducing the amount of sunlight absorbed by the surface of the Earth. If SRM suddenly stopped, the average temperature of the earth’ surface  would increase. SRM is suggested to be a controller of regional and local climate but it is not possible to use on a worldwide scale.

  • Cool roofs

    Cool roofs are the most common reflective surfaces that have a high solar reflectance and also a high thermal emittance. The reflectance is the ability of a material reflecting the sunlight and thermal emittance is the ability to radiate the absorbed energy.


    Researches have proved that greenhouses provide an increase in the surface albedo due to its color and texture: they are white and brilliant which reflect very well the solar radiation. Greenhouses are able to offset the radiative forcing by 2 W/m2.Higher surface albedo reduces net incoming shortwave energy.

  • Land & Farming Management

    Changes in grassland have been proposed to increase albedo. Grassland has an albedo of about 20%. This technique can give 0.64 W/m2 of globally averaged negative forcing, which is a minor contribution to offset the positive forcing from a doubling of CO2
