The abstract is: The "weekend effect" method (defined here as the average for Saturday through Monday minus the average for Wednesday through Friday) has been used to identify fingerprints of anthropogenic emissions. Based on the daily maximum and minimum temperature series from the China Meteorological Administration homogenized datasets, the weekend effect in diurnal temperature range (DTR) at 71 stations with elevations above 2000 m a.s.l. in the eastern and central Tibetan Plateau (TP) during 1961-2004 is examined, and Principal Component Analysis (PCA) is performed to cluster series into four subregions with similar weekend effect variability. The DTR in autumn and winter demonstrates a much stronger and opposite weekend effect and provides a strong evidence of anthropogenic activity in this region, especially in the central TP. Analysis by topographic type and degree of urbanization shows a clear weekly cycle which can not be explained by any microclimatic effect. We hypothesize that t! he interaction with anthropogenic aerosols from local emissions which are then transported by the atmosphere may account for the weekly cycle in the TP, despite this being one of the most remote and clear regions in the world.
