JEDI Log Diagnostics API

The log diagnostics subsystem provides tools for parsing a full JEDI variational DA log file and extracting structured diagnostic information.

Modules

JEDI Log Parser — Comprehensive Diagnostic Report Generator

This module parses a JEDI variational DA log file and extracts:

• Configuration metadata (cost type, analysis time, resolutions, weights)

• Observation counts (loaded, total, assimilated, per‑variable)

• Jo/n evolution across outer loops

• Cost‑function convergence (J, Jb, JoJc)

• Departures (Min/Max/RMS)

• Observation error statistics

• A full human‑readable diagnostic report

Typical usage:

python parse_jedi_log.py jedi.log –output report.txt

ufs_da_diagnostics.logs.parse_jedi_log.generate_report(config, obs_counts, jo_data, jo_total, convergence, departures, obs_errors)

ufs_da_diagnostics.logs.parse_jedi_log.main()

ufs_da_diagnostics.logs.parse_jedi_log.parse_configuration(lines)

ufs_da_diagnostics.logs.parse_jedi_log.parse_cost_convergence(lines)

ufs_da_diagnostics.logs.parse_jedi_log.parse_departures(lines)

ufs_da_diagnostics.logs.parse_jedi_log.parse_jo_evolution(lines)

ufs_da_diagnostics.logs.parse_jedi_log.parse_obs_counts(lines)

ufs_da_diagnostics.logs.parse_jedi_log.parse_obs_errors(lines)
