California Wildfires: Mapping Sonoma County

Sonoma County’s wildfire information page points to a number of useful maps: fire perimeter boundary maps, current evacuation areas, road closures, rapid evaluation safety assessment (RESA) maps. The City of Santa Rosa’s emergency information page also has maps specific to that city; Heavy also has a roundup. See also Cal Fire’s structural status information map. [The Mercury News]

Maps and satellite imagery of the wildfires in Northern California include the San Francisco Chronicle’s interactive map; Robin Kraft’s interactive map  showing satellite imagery from before and after the fire; this New York Times page mapping building damage in Santa Rosa; the Washington Post’s coverage of the devastation; and NASA Earth Observatory’s images of the smoke plumes here and here.

Satellite Imagery of Fort McMurray Wildfire Damage

Satellite imagery from the Pléiades-1A satellite showing the extent of wildfire damage caused to Fort McMurray, Alberta can be viewed through a web-based mapping application released by the government of Alberta. (Doesn’t work in Safari for Mac; works fine in Chrome.) [CBC News]

DigitalGlobe’s satellite imagery of the Fort McMurray wildfire, which uses “short wave infrared imagery (SWIR) to ‘cut’ through the smoke and identify the active footprint and burning hotspots” and reveals where buildings have been damaged or destroyed by the fire, can be viewed at Gizmodo and on DigitalGlobe’s own blog.

Here are some links to maps and satellite imagery of the wildfire that forced the evacuation of Fort McMurray, Alberta this week.

1. The fire is fuelled in part by abnormally high temperatures: 32°C (90°F) was reported earlier this week. The above temperature anomaly map, based on MODIS data from NASA’s Terra satellite, demonstrates how unusual these temperatures are: “The map above shows land surface temperature from April 26 to May 3, 2016, compared to the 2000–2010 average for the same one-week period. Red areas were hotter than the long-term average; blue areas were below average.”

2. NASA’s Earth Observatory is also assembling a collection of Landsat satellite images of the fire:

3. Smoke from the fire is making it into the United States, and turning up on NOAA imagery:

4. Maclean’s and CBC News have tried to depict the size of the fire by superimposing it on other cities in Canada and elsewhere in the world; so has Kyrstyn Morochuk, whose maps have been reposted by the Huffington Post. I’m not sure who came up with it first.

Yesterday wildfires swept through Fort McMurray, Alberta, the population centre of the oil sands industry, forcing the evacuation of nearly all of its more than 60,000 residents. It therefore seems timely to point to the maps produced by the Canadian Wildland Fire Information System. There are static maps of current conditions, fire danger maps providing an index of fire risk and potential damage (see above for today’s), and various forecasts, as well as an interactive version.

Sediment, Smoke, and Stained Ice in Quebec

Forest fires near Eastmain, Quebec had a dramatic impact on air quality around here last week; I woke up hacking and wondering why. (Air filters to maximum!) The above photo, taken by the MODIS sensor aboard NASA’s Aqua satellite on June 28, gives some idea of the situation on the eastern shores of James Bay. (The photo also shows a brown-stained James Bay, the result of tannin-stained water from bogs spilling into the bay in spring.) Image credit: NASA Earth Observatory.
