摘要：This paper presents data on research publications authored by scientists affiliated with Spanish institutions between 2016 and 2020, along with their associated social media and altmetric mentions, and on researchers affiliated with Spanish institutions whose work is highly mentioned on social media and non-academic outlets. The first dataset contains 219,988 records and 24 attributes. Each observation represents a scientific publication (article, review or letter) extracted from the Web of Science database. For each record, we provide bibliographic metadata, its subject area and a battery of altmetric indicators extracted from Altmetric.com. The second dataset includes 4209 records and four attributes. Each record corresponds to a researcher. For each record, we include their full name, an author identifier (ORCID), their affiliation and their list of publications connecting to the first dataset.
