Meteorological parameters from 5 30 surface stations in a mix of urban, rural and remote locations were analyzed for the time period 1983-2008, using three different tests: the Kruskal-Wallis test, a spectral analysis and a comparison of the regular 7-day week to constructed 6-and 8-day weeks. We expect a clear and statistically significant weekly cycle to pass all three tests.
