REAL BLUE SKY RESEARCH
Just where in the world is the bluest sky? Expedia wanted to know for its "Blue Sky Explorer" project. They asked NPL to develop a blue sky standard and some cheap equipment to measure it. Their solution was to use cheap light-emitting diodes as the light standard, rather than the typical expensive noble gas lamps, and the belt-and-braces device was calibrated against an international "colourimetry" standard. The result? Rio de Janeiro came out on top, followed by the Bay of Islands in New ?ealand and Uluru in Australia. Unsurprisingly the UK did not figure in strongly in the top 10, but Castell Dinas Bran in Wales came in at number nine.

II- Expedia used a previous blue sky standard in the research.
III- The lamps that are currently used in the measurement were replaced by cheap ones.
IV- NPL adjusted the device to use an international "colourimentry" standard.
V- Rio de Janeiro and New ?ealand got first rank in the Research while Australia came in second.
VI- It was a surprise that the UK did not figure in strongly in the top 10.
