Earth pictures every 10 minutes from new weather satellite

A powerful new weather satellite has just become operational, bringing amazingly detailed and frequent pictures of earth from space.

The new Himawari-8 geostationary meteorological satellite, managed by the Japan Meteorological Agency (JMA), began operating on 7 July 2015, replacing the previous MTSAT-2.

Himawari-8 was launched into space on 7 October 2014, but has since then been used for testing and calibration.

Such is the power of this new satellite, the JMA believes that it will have the capacity for superior earth monitoring, using it to open the door to a new generation of satellite meteorology.

A picture of earth every 10 minutes

One of the most significant features is the satellite’s ability to constantly take a picture of earth from space every 10 minutes.

On a country level, the satellite will offer pictures of Japan from space at a frequency of every two-and-a-half minutes, giving invaluable amounts of data.

However, as it is a geostationary satellite, it sits above earth in the same location, meaning that it only monitors one side of the planet – in this case, the Asia-Pacific and Australasia regions.

Nevertheless, its ability to capture such frequent images from space, combined with the fact that it offers more detail – down to a resolution of 0.5km – means that the monitoring of weather will become easier.

The benefits

Having such frequent and detailed images is invaluable for weather forecasting centres around the world.

Not only will they be able to monitor and study the progress of dangerous typhoons, they will also have more detailed data to put into weather computer models.

Weather computer models ingest satellite data to establish what is happening in the atmosphere right now. This information is then extrapolated to provide a forecast for the future. So the better the data that is put in, the better the forecast that comes out.

Given that the effects of climate change and phenomena such as El Nino are likely to have the greatest impacts on weather within the tropics, this powerful new satellite will contribute significantly to the prevention and mitigation of weather-related disasters in the future.

    AWESOME PHOTOS AND VIEWS,THANKS TO THE PEOPLE WHO MADE THIS HAPPEN.ME AND MY KIDS ARE AMAZED.LOVELY DAY.

    Why is it, when I screen shot this ‘picture’ of the earth and zoomed up on the curvature of the earth with my iPhone that I can quite plainly see that it has been cropped with paint?

    Call me a conspiracy theorist but I don’t buy this. It’s lies.

    Perhaps Europe should subscribe to a second Japanese satellite for our continent too?

    No need for us to re-invent that technology.
    Maybe NAFTA States will want another one too? Perhaps we could both make a joint offer for two of these satellites? Those might cover the western Atlantic and share info about the storms rolling up the eastern seaboard ready to bring rain on to St. Andrews?

    Could be useful for South Asia’s monsoon spotting.

    While giving the details of the weather after the news, in the UK map you show the wind direction and the speed but not the Temperature. Why not? People are more interested in temp. thant th e wind speed unless there is high wind.
    There is no harm in giving temp. and the wind speed,
    BBC weather gives both one inside a droplet and the other in a square box. Surely its not a great effort to give both.
    Please consider this seriously and I hope you would start giving both on the map.
    Thanks
