Attribution: Source: Hong Kong Observatory, Government of the Hong Kong Special Administrative Region. Data reproduced under the DATA.GOV.HK Terms of Use.

Licence: The Observatory publishes its datasets on DATA.GOV.HK, whose terms grant reuse explicitly: "Use of Data on DATA.GOV.HK You are allowed to browse, download, distribute, reproduce, hyperlink to, and print the Data for both commercial and non-commercial purposes on a free-of-charge basis on condition that:- you shall comply with the Terms of Use; you shall identify clearly the source of the Data and acknowledge the Government and the Relevant Organisations' ownership of the intellectual property rights in the Data and in all copies thereof including but not limited to paper copies, digital copies and copies placed on other websites; you shall indemnify the Government and the Relevant Organisations against any alleged loss or liability arising from or in connection with the use of the Data." The Hong Kong Observatory's own open data page links every dataset to its DATA.GOV.HK record and states no narrower terms, so the commercial, free-of-charge distribution grant applies. Attribution to the Hong Kong Observatory and acknowledgement of Government ownership are conditions of use.
