Learn how to protect yourself including which air filters and air purifiers to choose for your home.Įnvironmental impact: Wildfires send greenhouse gases into the air, but Canada doesn’t count some of them as part of its official emissions contributions, a Post report found. The fire has killed three people and destroyed 146 structures, and prompted evacuation orders for more than a thousand people, according to Cal Fire.

Here’s an explanation of what Code Red, Code Purple and more mean. The EPA uses a color-coded system to measure air quality. See how bad the wildfire smoke and air quality are in your area.Īir quality and your health: Breathing in wildfire smoke is bad for your health. Although temperatures will remain on the cooler side, the. and New York City was particularly poor, and officials urged at-risk residents to wear high-quality masks outdoors. The state’s large fires remained active Wednesday thanks to a front that pushed through the area, CNN meteorologist Michael Guy said.

Where wildfire smoke is the worst: Satellite images show smoke most densely covered the Northeast, but also extending into the Carolinas. Smoke from Canadian wildfires spread over much of the Midwest, Ohio Valley, Northeast and Mid-Atlantic.

Because of its finer spatial resolution (375 meters), it can detect smaller fires on the ground with a bit more accuracy.ĭetecting forest fires is just one of the hundreds of remote sensing and satellite applications in use today.Latest news: Why are Canada’s wildfires getting worse? Meteorologists aren’t sure how long the fires will continue to scorch parts of Canada.

VIIRS: Likewise, VIIRS on board the NASA/NOAA Suomi NPP detects active forest fires based on thermal anomalies. The AirNow Fire and Smoke Map provides information that you can use to help protect your health from wildfire smoke.

As explained above, it detects active fires by comparing temperature to neighboring pixels but it depends on the severity and extent of the fire.

MODIS: On board Terra and Aqua satellites, MODIS has a pixel resolution of 1 km.

But if the fire is too small to detect due to the spatial resolution of the sensor, the satellite won’t be able to detect it. If the difference is over a given threshold, it confirms the “hot spot” as an active wildfire. The fire detection algorithm compares the temperature of a potential fire with the temperature of the land around it. Fortunately, satellites can track forest fires and deliver warnings to emergency crews. History shows that when wildfires get out of hand, they can be costly and deadly to people nearby. Monitoring Real-Time Forest Fires with MODIS and VIIRS

As you can see below, here is a satellite view of the December 2017 wildfires in California. If you downloaded the correct date and time, you should be able to see the forest fire.

Finally, drag and drop the Landsat image into Google Earth Pro without any extra processing. The image type you want is Landsat Look with Geographic Reference (about 10MB).

If you want to see a snapshot of the fire, your best chance is to use a Landsat scene from the USGS Earth Explorer.įortunately, we have a tutorial on how to download Landsat data. As you can see above, the latest forest fires will pop up with fire symbols. Next, drag and drop the KMZ into Google Earth Pro. But really, all it takes is a bit of legwork to get started.įirst, download the latest active fire data from NASA. Even though the imagery is usually less than a year old, chances are that you won’t see a forest fire in the application. And the best part is that it’s never a cloudy day. Google Earth Pro is a handy tool that helps you sight-see the planet.
