We conducted a web survey of DIAS account holders in January and February 2022. Thank you very much for your cooperation.
We conducted this survey in Japanese and English, getting 769 replies, approximately 70% in Japanese and 30% in English. This ratio shows a similar trend to the survey in 2022.

Affiliations of DIAS account holders

About 60% were research institutions (universities, R&D agencies, etc.), about 1/4 were private companies, and about 10% were public offices and local governments. The “other” category includes NPOs, individuals, etc. The trend was similar to the results of the 2022 survey.

Awareness of DIAS services, applications

The most well-known in DIAS applications and services was “Data registration to DIAS,” about half of the respondents were also aware of “Release of the Climate Prediction Dataset 2022 from DIAS. The “DIAS FAQ page” and the “Results List and Results Registration Form” were also recognized by more than 40% of respondents.
