A pioneering climate scientist says global heating is accelerating. Others say we can still reach climate goals ...

2023 set a number of alarming new records. The global mean temperature also rose to nearly 1.5 degrees Celsius above the preindustrial level, another record. Seeking to identify the causes of this ...

TOA (Top Of Atmosphere) Reflectance is defined as the ratio between the radiant exitance and the irradiance at sensor level at the top of the Earth’s atmosphere. Delivered data is defined as technical ...

Both over the course of the year and over the course of Earth's history, growing plants and respiring microbes change atmospheric CO 2 levels and the albedo (reflectivity) of the Earth's surface.

In addition, experiments to evaluate the uncertainty associated with different albedo measurement conditions were carried out. They measured the surface reflectance of five different ground ...

Albedo: The measure of reflectivity of a surface, with higher values indicating more reflection of solar energy. Phenology: The study of the timing of seasonal events in the life cycle of ...

Carbon removal schemes involving enhanced rock weathering should consider whether the rocks they use are lighter or darker ...

The albedo of the surface – its reflectivity at the laser wavelength of 1064 nanometres – can also be determined from the relative intensity of the emitted and reflected pulses. Relationships between ...

Researchers at Sandia National Laboratories are taking a closer look at what's causing a decrease in sunlight reflectivity, or albedo, in the Arctic. Watch an animation showing the albedo process.
