Hi Matt, and thanks!
The time series charts are cumulative distinct fire counts per year (or season). The overall height shows the relative number of fire events, and within each bar the count proportionality of categorical wattage. Though the notion of a cumulative wattage time series chart is interesting!

@ John Nelson. Fantastic Image! Goes to show how creative graphics can really emphasize the point.
Question: What are the units/values of the y-axis on the bar graphs. # of fires? cumulative wattage?
Thanks, Matt

Thanks ac!
I used the continental US data source, but there is also a Canadian equivalent available. Here’s a link to that source data: http://activefiremaps.fs.fed.us/gisdata.php?sensor=modis&extent=canada

I don’t have plans to map it, though, but I’d like to see others’ maps in that area.

John Nelson, the maker of this image, has answered a couple user questions.

Cynthia Carlson: The map includes all fires.

A.A. Hoffmann: Good point about Terra v. Aqua launch and morning v. afternoon fires. John Nelson says, “If the nature of the question is about sensitivity and inclusion of smaller fires, which it looks like, this map only retains 100+MW fires so the minor fires are excluded over the whole period.”

Have you used both Aqua and Terra for this analysis?
If so how have you taken into account that Aqua was only launched mid 2002? I would assume this impacts the year 2001 and 2002 in particular the intensity as Terra depicts morning fires hence usually less intense fire.
if not skip the question

Wow, really interesting. Is this vegetation/forest fires only or a combination of all sorts of fires?
