Worked on enhancing radar product documentation within the MeteoSwiss/opendata repository, focusing on improving clarity and consistency for precipitation and hail radar data. Used Markdown to restructure and expand documentation, detailing data sources, file naming conventions, and data formats for products like PRECIP, PRECIP-SV, and CombiPrecip. Addressed reliability issues by fixing ODIM HDF5 external links and aligning documentation with established standards, ensuring accurate access to format descriptions. Emphasized maintainability and discoverability, supporting faster onboarding and correct data usage. The work combined documentation skills with a strong understanding of data-access workflows, resulting in clearer, more reliable technical resources for data users.
