Enhanced radiosonde sounding data have been used for assimilation

While radiosonde observation onboard the Mirai has been started since August 5, enhanced radiosonde soundings (from 12-hourly to 6-hourly) at Palau and Yap have also been started since August 6. In addition, it is expected to have another enhancement at PAGASA Legaspi site, Philippines soon.
Thank you, Palau Weather Service, Yap Weather Service, US/NOAA, and PAGASA for your great help and contributions!
According to the ECMWF report of geographical coverage of observations used for their data assimilation system, those enhanced sounding data have been successfully used by them! We can confirm three red dots in the tropical western Pacific, which were not appeared on the chart as of August 4.

Loading in the rain

During the R/V Mirai was at-berth at Shimizu Port from July 20 through 31, various observation tools were loaded and equipped. In particular, heavy instruments were loaded on July 30 using a crane truck.

This time, due to COVID-19 pandemic, on-board participants took PCR test prior to the cruise and all were proved as “negative.”  Now everything has been set for the start.

The R/V Mirai MR20-E01 cruise is scheduled to depart on the morning of August 1, 2020.  (KY)
