abstract = "Methane (CH4) and carbon monoxide (CO) total column amounts (TCA) measured at the Research Institute of Physics of St. Petersburg State University (Russia) were used for: 1. study of temporal variability of CH 4 and CO; 2. identification of source regions of CO and CH 4 using trajectory analysis. CH4 and CO showed distinct annual cycle with the amplitude of about 3% and 25% correspondingly. Period of 1999-2002 has a significant decline of CH4 TCA for the St. Petersburg region. The suggested reason is hot and dry summers of 1998-2002. October 1998 - March 1999 is characterized by the strong irregular disturbances of CO TCA.
