Mission to reveal ‘Truths’ about climate change

‘Truths’ is an acronym* but it helps with the publicity. The satellite ‘will be sensitive to light in the visible and near-infrared part of the electromagnetic spectrum’.

The UK is going to lead a space mission to get an absolute measurement of the light reflected off Earth’s surface, reports BBC Science.

The information will be used to calibrate the observations of other satellites, allowing their data to be compared more easily.

Called Truths, the new spacecraft was approved for development by European Space Agency member states in November.

Proponents of the mission expect its data to help reduce the uncertainty in projections of future climate change.

Scientists and engineers met on Tuesday to begin planning the project. Industry representatives from Britain, Switzerland, Greece, the Czech Republic and Romania gathered at Esa’s technical centre in Harwell, Oxfordshire.

The agency has allocated €32.4m (£27.7m) for the initial design phase, with the scientific lead on the mission to be taken by Britain’s National Physical Laboratory.

NPL is the UK’s “keeper of standards”. It holds references for the kilogram, the metre, the second and all other units used in the international system (SI) of measurement.

The lab is the place you go, for example, if you want a precise description of the intensity of a light source – something it’s able to gauge using a device called a cryogenic radiometer.

And the aim of the Truths mission is to get one of these instruments into orbit.

Working in tandem with a hyperspectral camera, the radiometer will make a detailed map of the sunlight reflected off Earth’s surface – off its deserts, snowfields, forests and oceans.

The map should be of such exquisite quality that it’s expected to become the standard reference against which all other imaging spacecraft will want to adjust and correct their own observations.

This ought to make it a much simpler task to compare the pictures from different satellites, not just from those missions flying today but also from the ones that have long since been retired and whose data now sits in archives.

    What uncertainty?

    Used to justify the project.

    The uncertainty will be gone tomorrow. You can resume preparing for The End.

    Yeah, one that doesn’t have the same difficulties all other satellites have…

    “€32.4m (£27.7m) for the initial design phase”

    Then how much to get it space worthy?

    And then if it doesn’t make it to orbit, or develops a fault?

    The Planck satellite intended to measure the absolute MBR was based on a black body reference, except the black body reference design was defective. End of absolute measurements. Did someone not inform them that ALL measurements are relative? Absolute only exists in computer simulation.

    I think the aim of this project is to have one master set of data that can be ‘edited’ and so destroy the usefulness of all the other satellites – want to show globull warming is increasing just edit the master and all the other data providers need ‘correcting’ and will show just what the UN Church of Climatology decrees.

  4. On the Thread “Game Over” I put that nothing has an emissivity of a black body ie e=1 as assumed by the alarmists. They are admitting that the Earth reflects light but a satellite to measure the reflection which is already well known is a waste of money which could be better spent on improving the welfare of poor countries particularly the poor in Muslim and Catholic countries so they do not have so many children. Look at Singapore one of the countries with the highest GDP/capita and they have to beg people and provide finance for couples to have children

    Not much truth about climate change here…

    Derby staff and students given climate change anxiety therapy
    3 hours ago

    Staff and students struggling with anxiety over climate change are being offered art therapy.

    Eco-anxiety sessions are being held at the University of Derby to tackle feelings of anger, guilt and grief.

    One student involved in the workshops said climate change makes her feel as though she is “not going to have a future”.
