      abstract     = {The variability and trend of ozone (O3) in the Upper
                      troposphere and Lower Stratosphere (UTLS) over the Asian
                      region needs to be accurately quantified. Ozone in the UTLS
                      radiatively heats this region and cools the upper parts of
                      the stratosphere. This results in an impact on relative
                      humidity, static stability in the UTLS region and tropical
                      tropopause temperature. A major challenge for understanding
                      ozone chemistry in the UTLS is sparse observations and thus
                      the representation of precursor gases in model emission
                      inventories. Here, we evaluate ozonesonde measurements
                      during August 2016 at Nainital, in the Himalayas, against
                      ozone from multiple reanalyses and the ECHAM6-HAMMOZ model.
                      We find that compared to measurements both reanalyses and
                      ECHAM6-HAMMOZ control simulation overestimate ozone mixing
                      ratios in the troposphere (20 ppb) and in the UTLS (55 ppb).
                      We performed sensitivity simulations using the ECHAM6-HAMMOZ
                      model for a $50\%$ reduction in the emission of (1) NOx and
                      (2) VOCs. The model simulations with NOX reduction agree
                      better with the ozonesonde observations in the lower
                      troposphere and in the UTLS. Thus, neither reanalyses nor
                      ECHAM6-HAMMOZ results can reproduce observed O3 over the
                      South Asian region. For a better representation of O3 in the
                      ECHAM6-HAMMOZ model, NOX emission should be reduced by
                      $50\%$ in the emission inventory. A larger number of
                      observations of ozone and precursor gases over the South
                      Asian region would improve the assessment of ozone chemistry
                      in models.},
