Mesmerising fly-over of Earth

NASA has released time-lapse footage of flying over Earth taken from the International Space Station. Turn off your mind, relax, and float downstream (but don’t forget to click the bottom right corner of the video to enlarge it).

One thing to note from a climate perspective is the different layers of the atmosphere that are visible through the film.

The white clouds that are visible in many parts of the film mark the top of the troposphere, the lowest portion of Earth’s atmosphere. It contains approximately 80 per cent of the atmosphere’s mass and 99 per cent of its water vapour and aerosols. It varies in 8-15 kilometres height around the globe.

Above the troposphere a range of visible effects are evident in the stratosphere and mesosphere.

Human activities are known to have impacted on the properties of these layers through damaging the ozone layer in the lower stratosphere and increasing greenhouse gases, particularly in the troposphere.

Wow, it’s a truly amazing perspective on our beautiful planet and our atmosphere.

Readers’ reflections welcome below.
