A district-scale MODIS-VIIRS mismatch analysis of Ghana's fire regime # ghana-fire-mismatch ## Overview `ghana-fire-mismatch` is a reproducible Ghana fire mismatch analysis repository. It compares two complementary satellite fire evidence streams in a common spatial and monthly framework: - **VIIRS active-fire detections**, treated as a thermal activity signal. - **MODIS MCD64A1 burned area**, treated as a mapped burned-area impact signal. The repository prepares spatial units and fire-observation panels, merges active-fire and burned-area evidence, and runs the Ghana MODIS burned-area and VIIRS active-fire mismatch analysis. The public project contract is: ```text data_processing/ prepares spatial units, fire panels, and merged analysis inputs. mismatch_analysis/ consumes the merged panels and writes mismatch outputs. ``` ## Scientific scope The project compares product signals, not product truth. The core interpretation rules are: - VIIRS active fire is a thermal activity signal. - MODIS MCD64A1 burned area is a mapped burned-area impact signal. - The products are complementary, not interchangeable. - VIIRS active fire is not treated as validation for MODIS burned area. - MODIS burned area is not treated as validation for VIIRS active-fire detections. - Mismatch states are observational classifications, not direct error labels. - The workflow supports descriptive and diagnostic analysis; it does not identify causal drivers. The primary mismatch states are: ```text both-zero VIIRS-only MODIS-BA-only both-positive ``` ## Repository layout ```text ghana-fire-mismatch/ |-- README.md |-- LICENSE |-- CITATION.cff |-- environment.yml |-- pyproject.toml |-- docs/ | |-- workflow.md | |-- data_access.md | |-- data_contracts.md | |-- output_provenance.md | |-- reproduction.md | |-- github_release_checklist.md | `-- known_limitations.md |-- data_processing/ | |-- README.md | |-- merge_af_ba_panels.py | |-- tests/ | |-- geo_data_prep/ | |-- rp1_mv_firms_panels/ | `-- rp1_gee_ba_scripts/ |-- mismatch_analy …
