Incoming energy absorbed by earth and its atmosphere: Top-of-atmosphere (TOA) shortwave flux radiation, shows energy (in watts per square metre) received from the Sun as inferred from CERES measurements (26–27 January 2012). Brightest white areas show the highest reflectivity (least absorption) of solar energy, while darkest blue areas show the greatest absorption.

Outgoing energy radiated by earth and its atmosphere: Top-of-atmosphere (TOA) longwave flux radiation (26–27 January 2012). Heat energy radiated from Earth (in watts per square metre) is shown in shades of yellow, red, blue and white. The brightest-yellow areas are the hottest and are emitting the most energy out to space, while the dark blue areas and the bright white clouds are much colder, emitting the least energy.

Reason

This set of videos shows a snapshot of the energy absorbed (incoming, blue image) and the energy radiated (outgoing, red image) by the earth and its atmosphere. The data includes transient atmospheric effects (cloud contributions). The data was collected over a two day period in January 2012. This set is informative in the two articles and helps explain the subject. If this nom gets a few supports, I will convert the video formats to WebM (which is preferred to ogv).

• One can't help but feel that using different colour scales for things meant to be compared, and the inability to watch them next to each other, makes this an awkward set. A simple map projection - ideally without the missing information in the top image - would allow easy comparison. Adam Cuerden ^(talk)_{Has about 8.2% of all FPs} 13:57, 3 October 2022 (UTC)

• It isn't a simple comparison, their physics are different. The incoming is shortwave radiation (blue, as in optics) and the outgoing is longwave (red, as in optics). The outgoing includes energy storage effects, but the incoming has no such thing. The outgoing relates to heat on Earth (red being a natural choice), and the incoming related to input from outer space (blue being Earth's natural color from outer space). Yes a map would be easier to look at. However, the incoming video conveys a spatial relation between the energy source (the Sun) and the revolving of Earth (useful for novice readers). There is an advantage in either type of illustration. The missing data on the incoming video is unfortunate, but this isn't an everyday type of measurement, IMO it's good enough.

• That's the missing information (data) that Adam and I are referring to above. Bammesk (talk) 01:53, 5 October 2022 (UTC)
