Third-Party Observing Time

A limited amount of observing time on the EISCAT facilities is available for international competition by peer-review

Successful applications will receive free observing time, including initial data reduction (if using standard experimental arrangements) and copies of the raw and quick-look analysed data, but, in general, at least one experimenter will be expected to be present at EISCAT during operations.

Eligible countries

Third-party time can be granted to users world-wide excluding the EISCAT Associate countries: China, Finland, Germany, Japan, Norway, Sweden and the United Kingdom.

Submission address

EISCAT Headquarters (EISCAT Scientific Association, PO Box 812, Kiruna SE-981 28, Sweden) is the correct place to send applications for EISCAT observing time. Applications may also be submitted by email through EISCAT's Senior Scientist, Ingemar Häggström.

Peer-review process

Applications will be reviewed by the EISCAT Scientific Oversight Committee.


The EISCAT Scientific Oversight Committee reviews applications twice per year, with application deadlines at the beginning of February and August. In order to ensure that there is adequate time to complete the review and time allocation procedures, applicants should normally submit requests before 1 February, for experiments to be run after 1 July the same year, and before 1 August for experiments to be run after 1 January the following year.
