“…Figure 1 shows measurement data on tropospheric ozone by two instruments for the total time period (157 points). One can clearly see the abovementioned (12) tendency: at medium and low values of tropospheric ozone content, the ground based measurement values exceed the satellite data, and at high higher values, the satellite data exceed the ground based measurements. However, it should be noted that the maximum differ ence between the two ensembles is observed in Janu ary-February, which can be caused by both the increased measurement errors in winter and differ ences in the compared air masses.…”

“…The relevant ground based spectral system was described in [11]. Examples of determining the total content of different gases with the help of this system can be found, for example, in [12][13][14]. In this paper we ana lyze the influence of different sources of errors on the error in the calculation of ozone content, investigate the seasonal variations in ozone content in different layers of the atmosphere, and compare the results of ground based measurements of ozone content with satellite measurements (conducted by IASI [15] and MLS [16] instruments) in different layers of the atmo sphere.…”

For the first time in Russia, using ground based measurements of direct solar infrared radiation, we derived data on ozone content in different layers of the atmosphere. The measurements were conducted with the help of a Bruker IFS 125HR Fourier spectrometer in 2009-2012 in Petergof, which is 30 km west of the center of St. Petersburg. The errors in determining the ozone content by this method in the troposphere (0-12 km), in the stratosphere (12-50 km), in the layers of 10-20 and 20-50 km, and in the layers of 12-18, 18-25, and 25-50 km were ~4, 3, 3-5, and 4-7% (taking into account the instrumental and method ological errors, as well as the errors in specifying the temperature profile), respectively. The seasonal variation of tropospheric ozone content in the layer of 12-18 km is characterized by a clearly expressed maximum in March and a minimum in November, with amplitudes of 30 and 40%, respectively. For the layer of 18-25 km, the maximum and minimum are reached in the winter-spring period and late summer, respectively; the amplitude of the seasonal variation is ~20%. The amplitude of the annual variation in ozone content in the layer of 25-50 km is around 30%, with a maximum close to the summer solstice and a minimum close to the winter solstice. Over the three years of observations, the growth in the ozone content in this layer was ~10% per year of its value averaged over the time period. Comparisons of ground based measurements with satellite measurements (by the IASI instrument) of tropospheric ozone revealed a discrepancy of (3.4 ± 17)% for both ensembles. The correlation between the two ensembles is 0.76-0.84 (depending on the season). Comparisons between ground based and satellite measurements (by the MLS instrument) of stratospheric ozone revealed no systematic discrepancies of the two ensembles. The rms errors were 13, 6, and 5% for the layers of 10-20, 20-50, and 10-50 km, respectively; the coefficients of correlations between the two types of measurements were 0.82-0.94.

Atmospheric methane column-mean mole fractions measured with ground-based Fourier-transform spectroscopy near Saint-Petersburg, Russia (59.9° N, 29.8° E) are compared with similar data obtained with the Japanese GOSAT satellite in years 2009–2012. Average CH₄ mole fractions for the GOSAT data version V01.xx are by −13 ppb less than the corresponding values obtained from ground-based measurements on the same date (with standard deviation ~ 26 ppb). For the GOSAT data version V02.xx the average difference is ~ 4 ppb and standard deviation ~ 15 ppb. This shows that FTIR spectroscopic observations near Saint-Petersburg could agree with GOSAT satellite data
