How to interpret
Observatory readyDataset: January 2001–December 2024
Historical intelligence only: this Observatory is not a live-warning, emergency-response, forecasting or fire-spread service.
National fire-intelligence snapshot
Selected-metric burden, annual direction, seasonal timing and district concentration for the applied geography.
Annual selected-metric trend
Supported annual observations for the selected geography and period.
Annual selected-metric trajectory for the current period and scope.
Monthly seasonal profile
Average monthly activity over supported years.
Average monthly selected-metric profile for the current period and scope.
District context map
Selected-period district values use the governed Ghana-only SVG geometry.
Leading districts
Ghana district context map and keyboard-accessible ranking for the selected metric.
Dataset context and calculation notes
Ghana fire calendar
Explore monthly timing across years and compare how fire calendars differ among agro-climatic zones.
Year-by-month fire calendar
Select a cell for its governed value, transformation, support state and annual context.
Month-by-year heatmap for the selected metric and scope.
Selected month detail
Accessible monthly summary
Zone fire-calendar comparison
Desktop uses five zone small multiples; narrow screens use one selectable zone line.
Monthly comparison across Ghana’s five agro-climatic zones.
Spatial patterns
Locate where historical fire activity and burned impact are concentrated across Ghana’s governed districts.
The Ghana-only map uses governed district SVG paths and no external map service. The default 95th-percentile cap changes colour only: exact values, rankings and District Profiles remain uncapped.
Interactive district fire map
Colour, pattern and outline reflect the selected metric, period, support state and selection.
Ghana-only district map for the selected metric, period and zone. District search and ranking provide keyboard-equivalent selection.
District ranking
Ranking values use the selected period and geographical scope. Competition ranks preserve ties.
District ranking for the selected metric.
Unavailable or undefined districts
Two-district comparison entry
Select no more than two supported districts. The full comparison chart is opened deliberately on District Profiles in the next analytical step.
District Profiles
Compare one district’s historical fire record with its agro-climatic zone, Ghana and one optional comparison district.
District — of 260
District locator map
Ghana with the selected district outlined. The map is a locator, not a second analytical choropleth.
Compact Ghana locator map with the selected district highlighted.
District metadata and support
Governed identifiers and area denominators used by the Profile calculations.
Competition ranking assigns equal values the same rank and leaves the corresponding gap before the next rank.
District annual history
The selected district’s governed annual values.
Annual history for the selected district and metric.
Benchmark comparison
Indexed mode sets each supported series’ selected-period mean to 100; absolute mode uses separate panels.
District, zone, Ghana and optional second-district benchmark comparison.
Monthly climatology
Monthly values load only when the Profile page needs them.
Average monthly profile for the selected district, preserving support and valid-zero states.
Sensor and product comparison
Compare MODIS and VIIRS as distinct active-fire products and inspect the separate burned-area–VIIRS mismatch contract.
MODIS and VIIRS active-fire detections remain separate products. Complete annual comparison uses 2013–2024; Advanced monthly comparison begins in February 2012 and excludes January 2012.
Active-fire detection states
These states compare positive detection status for MODIS and VIIRS. They are not the burned-area mismatch states below.
Raw MODIS versus VIIRS detections
The observation unit and comparison representation follow the active controls.
MODIS and VIIRS comparison for the selected supported observations.
Ghana sensor trajectories
Ghana is always shown. A selected zone is added as a clearly labelled secondary scope.
Separate Ghana MODIS and VIIRS annual trajectories.
MODIS burned-area presence–VIIRS mismatch states
Secondary technical view: monthly product-state comparison from February 2012 through December 2024. Neither product is treated as truth.
Monthly mismatch data load when this page is opened.
Burned-area–VIIRS mismatch counts for the governed February 2012–December 2024 period.
Can the current data and visualisations be trusted for the selected historical analysis?
Independent expectations are compared with the browser runtime, rendered output and deployment resources.
Coverage years affect only period-sensitive support checks. Fixed release-integrity checks always cover the complete January 2001–December 2024 contract.
Live checks have not run in this session.
