Between 1977 and 2006, the Beijing meteorological station was moved from a suburban site to a more urban location (1981), then back to the suburban site (1997). Daily observations from this station, and 18 others nearby, show a mean difference between urban and suburban locations of 0.81°C (1.46°F) around 1981 and 0.69°C (1.24°F) around 1997, suggesting that urbanization effects had increased in the suburbs relative to downtown by 1997. Overall, Beijing appears to have warmed by about 0.48°C (0.86°F) per decade during the period, with another 0.30°C (0.54°F) at the Beijing station likely related to urbanization.
