PROFILE
Ashley Griffin
Ashley contributed to the JCSDA-internal/ioda-converters repository by developing support for ISU METAR data ingestion and improving the reliability of Tropomi NetCDF file processing. Using Python and shell scripting, Ashley extended the metar_csv2ioda converter to parse new CSV header formats and extract additional observation fields, updating tests and configurations to ensure compatibility with existing workflows. To address data pipeline stability, Ashley implemented robust error handling for malformed NetCDF files, allowing the converter to skip invalid inputs and emit warnings without interrupting processing. This work demonstrated depth in data conversion, file handling, and testing, enhancing both data coverage and operational resilience.

Mar 1, 2025In March 2025, delivered ISU METAR data support for the IODA converters project (JCSDA-internal/ioda-converters). Key work included extending metar_csv2ioda to parse ISU ASOS-AWOS-METAR CSV headers and extract corresponding fields, updating tests and configurations to reference ISU METAR data, and ensuring the workflow remains compatible with existing IODA pipelines. The change enables ingest of ISU METAR observations, broadening data sources and improving weather analytics. The change is tracked in commit 6c7bfdce2b935ab229f23bd01b67b4122fff340e (Update metar_csv2ioda converter for ISU data (#1619)).
