WorldClim V1 Bioclim fournit des variables bioclimatiques dérivées de la température et des précipitations mensuelles afin de générer des valeurs plus pertinentes sur le plan biologique.
Les variables bioclimatiques représentent les tendances annuelles (par exemple, la température annuelle moyenne, les précipitations annuelles), la saisonnalité (par exemple, la plage annuelle de température et de précipitations) et les facteurs environnementaux extrêmes ou limitants (par exemple, la température du mois le plus froid et le plus chaud, et les précipitations des trimestres les plus humides et les plus secs).
Le schéma des bandes est celui d'ANUCLIM, sauf que pour la saisonnalité de la température, l'écart-type a été utilisé, car un coefficient de variation n'a pas de sens avec des températures comprises entre -1 et 1.
La version 1 de WorldClim a été développée par Robert J. Hijmans, Susan Cameron et Juan Parra, au Museum of Vertebrate Zoology, University of California, Berkeley, en collaboration avec Peter Jones et Andrew Jarvis (CIAT), et avec Karen Richardson (Rainforest CRC).
