Motivation SPECTRE is an open-source database containing standardised spatial data on global environmental and anthropogenic variables that are potential threats to terrestrial species and ecosystems. Its goal is to allow users to swiftly access spatial data on multiple threats at a resolution of 30-arc seconds for all terrestrial areas. Following the standard set by Worldclim, these data allow full comparability and ease of use under common statistical frameworks for global change studies, species distribution modelling, threat assessments, quantification of ecosystem services and disturbance, among multiple other uses. A web user interface, a persistent online repository and an accompanying R package with functions for downloading and manipulating data are provided. Main Types of Variable Contained SPECTRE is a GIS product, currently with 21 geoTiff raster layers with an approximate 1 × 1 km resolution. Spatial Location and Grain Global (longitude −180–180, latitude −60–90) terrestrial database with a resolution of 30-arc seconds (approximately 1 × 1 km at the equator), converted from global sources of different original spatial grain, from 0.03 × 0.03to 10 × 10 km. Time Period and Grain The known time period for all sources present in SPECTRE varies from 1976 to 2020 (all but three after 1990), with a minimum temporal grain of 1 year. Major Taxa and Level of Measurement Non-taxa-specific. Software Format geoTiff and R.
