APEX is an airborne hyperspectral imaging instrument that is celebrating 10 years of operation. You can read about some of the scientific highlights from the period in this blog.
APEX has also been in demand for a number of airborne missions that were supported by EUFAR with Transnational Access funding. You can read about one such application in this earlier EUFAR article. Whilst EUFAR does not currently have funding available for other such projects, it may still be able to assist potential users with access to the instrument and its data. You can continue to submit an Expression of Interest on the EUFAR website.
