Abstract

The monitoring of tropospheric ozone has recently been enforced since it is both a greenhouse and a pollutant gas; it also plays an important role in various chemical and photochemical processes. The time series of ozone tropospheric columns in the 0-8 km layer (TrOCs) derived from spectral measurements of the IASI instrument (MetOp satellites) using two different algorithms (IASI_LATMOS and IASI_LISA) and from combined measurements by the IASI and GOME-2 instruments (IASI-GOME2) were compared to daily averaged ground-based measurements using the Bruker IFS 125HR Fourier spectrometers (FTIR) at three NDACC sites (high-latitude Kiruna, mid-latitude St. Petersburg, and subtropical Izaña). The analysis of temporal variability of TrOC series at different scales (from day-to-day variability to trend estimates) demonstrates that IASI_LATMOS and IASI_LISA data better reproduce FTIR TrOC variability than IASIGOME2 measurements. Standard deviation of differences derived from direct comparison of satellite and ground-based TrOCs total 9-13% for IASI_LATMOS, 12-16% for IASI_LISA, and 16-22% for IASI-GOME2 data. Further validation of IASI_LATMOS ozone data is required to determine the limits and applicability of using these data for global analysis of spatial and temporal variability of TrOCs.
