Processing

Set the timescale using the radio buttons. Selecting an IPCC AR6 region will take you to a page showing the timeseries of all variables processed.

Regional aggregation

The raw data is at 0.25 degrees resolution. The IPCC AR6 land region mask is used to compute aggregated totals at the monthly, yearly (JAN-DEC), yearly (JUL-JUN), seasonal (DJF), seasonal (DJF), seasonal (MAM), and seasonal (SON) timescales. The IPCC AR6 land regions abbreviations have the following meaning:

1. GIC      Greenland/Iceland
2. NWN      N.W.North-America
3. NEN      N.E.North-America
4. WNA      W.North-America
5. CNA      C.North-America
6. ENA      E.North-America
7. NCA      N.Central-America
8. SCA      S.Central-America
9. CAR      Caribbean
10. NWS      N.W.South-America
11. NSA      N.South-America
12. NES      N.E.South-America
13. SAM      South-American-Monsoon
14. SWS      S.W.South-America
15. SES      S.E.South-America
16. SSA      S.South-America
17. NEU      N.Europe
18. WCE      West & Central-Europe
19. EEU      E.Europe
20. MED      Mediterranean
21. SAH      Sahara
22. WAF      Western-Africa

Variables

(1) Area Burned by All fires

The total area burned by fires in the region in units of thousands km².

(2) Area Burned by Forest Fires

The total area burned by forest fires in the region from gridcells having 30% tree cover in units of thousands of km².

(3) Carbon Emssions from All Fires

The total carbon emissions from all fires in the region in units of thousands of tonnes of C.

(4) Carbon Emissions from fires in forests

The total carbon emissions from forest fires in the region from gridcells having 30% tree cover in units of thousands of tonnes of C.

Statistics

The timeseries are fit with a robust OLS regression (Theil-Sen) and a regression t-test is performed to determine if the OLS slope is significant at the 95% confidence level (p < 0.05, α = 0.05). This is only shown when the alternative hypothesis is true. The uncertainty band for the 95% confidence interval on the slope and intercept is provided. For each timescale (with the exception of the monthly data), 5-yr means are shaded as a visual guide to help understand the variability and potential trend in the data.
