    　Atmospheric nitric oxide (NO) and total reactive nitrogen (NOy) were measured at the top of Mt. Fuji during the summer in 2016.  A primitive result is shown in Fig. 1.  The concentration of NO was under the detection limit (0.2 ppb) during the observation period.  The concentration of NOy was fluctuated up to 2 ppb during the observation period.
