Temperature check: ThernUK Met Office has asked the World Meteorological Organization (WMO) to create a new data set of global land-surface air temperatures. By reanalysing existing temperature measurements from meteorological stations, the "robust and transparent" data set would provide daily or perhaps even more frequent figures. At present, only monthly averages are offered by the three existing global data sets (maintained by the Met Office, NASA's Goddard Institute for Space Studies and the US National Climatic Data Center). A WMO spokesman says that the concept will require three years of work and several million euros.
