Review of PAGASA Applications Programming Interface (API) for weather-informed agro- advisories through Climate+

This report presents a technical review of the PAGASA Ten-Day and Seasonal Weather Forecast APIs to assess their structure, accessibility, and compatibility with the Climate+ system. The review aims to identify strengths, limitations, and implementation considerations that are relevant not only for technical integration but also for inter-agency coordination, shared standards, and future enhancements of climate information services. The findings are intended to support informed decision-making among PAGASA, IRRI, and partner institutions, and to contribute to the continued improvement and governance of climate data services for agricultural applications.
