File Formats

The WOUDC uses ASCII text file format standard for data submissions in an extended (ext) Comma-Separated Value (CSV) format.

The extended CSV (extCSV) is the standard data file format for submission to WOUDC. The extended standard for the CSV syntax rules support the provision of comments and multiple data content within individual files. The extCSV provides a simple text-based format for data providers when submitting data to the WOUDC, as well as one of many ways for users to integrate ozone and ultraviolet (UV) radiation data into their database, spreadsheet and workflow analysis.
