"What caught our eye was that, in both the NASA and ECMWF datasets, 2023 stood out as the year with the lowest planetary albedo," says co-author Dr. Thomas Rackow from the ECMWF. Planetary albedo ...

“2023 stood out as the year with the lowest planetary albedo,” says study co-author Dr Thomas Rackow of the ECMWF. ‘Planetary albedo’ is science speak for the percentage of the sun’s ...

The James Webb Space Telescope has detected water vapor and thick clouds on LTT 9779 b, an ultra-hot Neptune locked in a ...

The environment on our planet has evolved on geologic timescales in response to variations in solar input, planetary albedo, and the trace gas content in our atmosphere. Investigation of how the ...

Winter 2024/25 was Wick’s mildest since that of 2018/19. Mean air temperature was 5.06C (41.11F). The burgh’s mean air ...

In general terms (Harte 1988), the energy absorbed by the Earth can be written as: E I = (1 – a) * Ω/4 ‘a' is planetary albedo (0.31, this is the proportion of incoming radiation reflected ...

Ice is diminishing rapidly in both polar zones, changing planetary albedo, and methane outgassing from the Arctic is increasing greenhouse gases in Earth's atmosphere. The Arctic in particular is ...

Uranus radiates more energy than it gets from the sun, two new studies find — just as Jupiter, Saturn and Neptune do.

But there are many locations on the planet that restrict fly overs, and the cost for regular over-flights by aircraft adds up quickly. Albedo's first big test may come within the next week and the ...
