The series of ground-based high resolution Fourier-transform measurements of atmospheric transmittance in near infrared region (4000-10000 cm -1) recorded at the Ural Atmospheric Station in 2012-2013 was processed in order to retrieve relative concentrations of CO 2 and CH 4 in atmospheric column. Retrieved values of methane concentration do not show a noticable seasonal cycle, while retrieved CO 2 concentrations show clear seasonal variations with high amplitude, which are also observed in GOSAT measurements over Ural region. The estimated amplitude of CO 2 seasonal variations is 14-15 ppm. Intercomparison between ground-based and GOSAT measurements of CO 2 shows a good agreement, while satellite values are overestimated by approximately 3 ppm. There is no noticable correlation between CH 4 values, which one can explain by presence of local methane sources in the area of GOSAT observations.
Translated title of the contributionThe amplitude of the CO 2 seasonal cycle in the atmosphere of Ural by ground-based and satellite remote sensing techniques
