Intra-seasonal variability in tropospheric ozone and water vapor in the tropics
Nearly two years of tropospheric O3 and H2O data from the Aura Ozone Monitoring Instrument (OMI) and Microwave Limb Sounder (MLS) instruments are analyzed to study the characteristics of intra-seasonal oscillation (ISO) of 20–100 day periods. The analysis shows the presence of ISO signals in O3 and...
