　　Atmospheric CO2 concentration was continuously measured by Picarro greenhouse gas analyzer from June 2012 to February 2013 in Wuhan City,a metropolis in central China,in order to study the effects of wind direction,wind speed and air mass transport on urban atmospheric CO2 concentration.The results revealed that the diurnal variation of atmospheric CO2 concentration showed the single-peak pattern in summer and autumn,with the lowest value observed in the afternoon and the highest in early morning.
