At last, we will start intensive radiosonde observation from tomorrow. Radiosonde can measure vertical profiles of temperature, humidity and winds from ocean surface to 20 km height or more. While a semi-auto launcher system is equipped in the sea container onboard the Mirai, we sometimes launch the balloon manually when we cannot operate the ship accordingly due to conflict with other operation or bad weather condition. Thus, today we had a drill to learn how to launch radiosonde manually.
We noticed atmospheric convections around the Mirai has become active, as if they waited for our observation.
