Diana Lopez Tavares enhanced the Spanish localization of the greenhouse-effect simulation in the phetsims/greenhouse-effect repository, focusing on improving clarity and naturalness for Spanish-speaking users. She revised the greenhouse-effect-strings_es.ftl translation file, applying her expertise in internationalization and localization to correct grammar and refine phrasing. Working with FTL, Diana addressed translation ambiguities and ensured that user interface text was both accurate and accessible. Although her work did not involve bug fixes or new features beyond localization, her targeted updates improved user comprehension and prepared the simulation for broader accessibility, demonstrating careful attention to linguistic detail and user experience.
