Measurement of noble gases in Antarctic ice cores

08-Jan-2018 - The average sea temperature is an essential parameter of the global climate – but it is very difficult to measure. At least until now, because an international team of researchers including Empa scientists have now developed a novel method using the concentration of noble gases in the eternal ...

A big step towards the redefinition of the kelvin

PTB scientists determine a new value of the Boltzmann constant

28-Sep-2011 - Metrologists are measurement artists who are very precise – in the case of the Boltzmann constant up to the sixth decimal place. Whoever is able to determine it very exactly will cause a small revolution in the field of worldwide temperature measurement: The temperature unit will then no longer ...
