Lorenzo Clementi enhanced the MeteoSwiss/opendata repository by improving documentation for precipitation and hail radar products. He clarified data sources, formats, and file naming conventions for PRECIP, PRECIP-SV, and CombiPrecip, making it easier for users to discover and interpret radar datasets. Using Markdown and focusing on documentation best practices, Lorenzo also addressed reliability issues by fixing ODIM HDF5 external links, ensuring accurate references to data format standards. His work improved consistency across radar product pages, supporting faster onboarding and more reliable data usage. The depth of these updates strengthened maintainability and alignment with established meteorological data standards.
