Q & A
What was Kate Darganβs first experience with large-scale fire, and how did it affect her perspective?
-Kate Dargan's first experience with a large-scale fire was during the Cedar Fire in 2003, where she witnessed chaos, destruction, and rows of houses burning. This experience made her realize that there must be a better way to handle wildfires.
How have wildfires changed over the past 20 years, according to Juliet Rothenberg?
-Wildfires have dramatically increased over the past 20 years, which was anticipated by climate scientists. However, the extent of the human cost and the global impact has been unprecedented and underestimated by many.
What was one of the main challenges faced by Googleβs research group when trying to address wildfires?
-One of the main challenges was the lack of reliable data on how wildfires spread and where they were located. Satellite images often mistook other elements like clouds, ponds, or smokestacks for fires, making it difficult to track fires accurately.
How is AI and machine learning used in Googleβs approach to detecting wildfires?
-AI and machine learning are used to analyze satellite images and detect fires in real time. By combining thousands of past images of the same area, the AI can determine whether the current images show signs of fire. This system enables more accurate and timely fire detection.
What is FireSat, and how does it improve wildfire detection?
-FireSat is a satellite-based program designed to detect wildfires. It uses a constellation of satellites in low Earth orbit to monitor the entire globe every 15 to 20 minutes, providing rapid, high-resolution images to spot fires as small as a classroom. This significantly improves the current detection systems, which revisit areas less frequently and at lower resolutions.
What role does Cathy Olkin and her team at Muon play in the FireSat project?
-Cathy Olkin and her team at Muon are responsible for designing, building, and operating the FireSat mission. Their role is crucial in making sure the satellite system functions optimally to provide accurate wildfire data.
How does the Rothermel fire spread equation contribute to current firefighting efforts, and what are its limitations?
-The Rothermel fire spread equation, developed in the 1960s, is the foundation for current fire behavior modeling and firefighter training. However, it does not account for changing fire conditions like wind, moisture, or vegetation variability, making it less adaptable to real-time fire behavior changes.
How has Google's partnership with fire scientists like Mark Finney enhanced fire behavior modeling?
-By leveraging Googleβs massive computing power, scientists like Mark Finney have been able to run millions of simulations and generate data points for fire behavior. Google then used this data to train deep neural networks, allowing for much faster and more accurate fire predictions, reducing prediction times from a minute to 20-30 milliseconds.
What advantages does FireSat offer to firefighters and first responders?
-FireSat provides real-time data that helps first responders detect and respond to fires quickly, improving their ability to protect communities and ecosystems. The system also aids in training by allowing simulations of different fire scenarios, improving preparedness for unexpected fire behavior.
How does Google incorporate wildfire detection data into its existing services?
-Google uses wildfire boundaries detected through satellite imagery and AI in its Google Maps and Google Search services, providing people with real-time information during crises to help them stay safe and make informed decisions.

Transcripts
KATE DARGAN: In 2003, we were called down to the Cedar Fire.
It's orange everywhere, and smoke is blowing.
And I just see the rows of houses burning.
I see horses running wild trying to escape the flames.
That was my first experience in fire
at that pace and scale of chaos and destruction.
And what I walked away with is
there has got to be a better way.
JULIET ROTHENBERG: Fires have dramatically
increased over the past 20 years in a way
that climate scientists anticipated.
But I don't think any of the rest of us really understood
what the cost ultimately would be.
We're seeing a human cost to communities and impacts
around the world that are really unprecedented.
CHRIS VAN ARSDALE: So the research group at Google
was trying to find ways of using technology to help address fires
and to help manage natural ecosystems.
We realized one of the main issues
was that there just wasn't a lot of good data for how fires
spread, or where they even were half the time.
Because in a satellite image of the Earth,
there's a lot of things that can be mistaken for a fire.
Clouds reflecting sunlight, a pond that's
reflecting light back into space,
something that's hot like a smokestack.
All of these things could look like a fire,
especially when you're looking at a relatively coarse pixel.
We realized that if we can pair satellites
with machine learning and artificial intelligence,
it was the perfect platform to generate
real-time operational intelligence on fires.
So we designed and built a camera
in order to optimize for machine learning-based fire detection.
We spent a long time testing it on an aerial platform,
flying over controlled burns, trying
to establish a baseline for what the machine learning algorithms
would have to pick out.
AI and ML will allow us to take the last 1,000 times we saw
a particular spot on the earth and estimate whether or not
the images that we're seeing now have a fire in them or don't.
So the Google team really focuses on the data.
The Muon team is helping bring that to the first protoflight
satellite.
CATHY OLKIN: At Muon, we are designing, building,
and we'll be operating the FireSat Mission.
CHRIS VAN ARSDALE: FireSat is a program
that we started with satellite experts
and a number of nonprofits.
It will be a new constellation of satellites in low Earth
orbit, and be able to see the whole globe every 15
to 20 minutes and spot a fire, both
when it starts and for its full evolution.
CATHY OLKIN: A number of satellites do many things,
but FireSat is focused on the problem of wildfire.
CHRIS VAN ARSDALE: Satellites today
that are used to do detection and tracking for fires,
they come by roughly once every 12 hours
or have very low resolutions.
At best, you're going to get something
that's two or three acres in size before you can actually
see a fire.
The main improvement FireSat is going to provide
is really this rapid temporal revisit,
especially at the really high resolution needed
to see the fires when they're very tiny in size,
roughly the size of a classroom.
CATHY OLKIN: We've had more than 200 interviews
with first responders and incident
commanders across the globe to understand the diverse needs
of people in this area.
KATE DARGAN: I was a line firefighter for decades,
and I finished as the state fire marshal of California.
So I was aware of some information gaps
in the firefighting space.
This is a global data stream that
will be distributed for the use of first responders
to get to places to protect communities
and ecosystems quickly.
And that's just the firefighting part.
CATHY OLKIN: We also want to provide data to fire scientists
so that they can improve models of fires.
MARK FINNEY: The foundation of all of our fire behavior
modeling systems is the Rothermel fire spread equation,
developed by Dick Rothermel in the 1960s based on experiments
at this very laboratory.
It's the foundation for firefighter training materials
and for all of the modeling systems
that people rely on to support decisions
associated with fighting fire and fire management.
One of the major limitations of it
is that it doesn't explain how fires spread.
It does not allow you to take into account
the changing of fire behavior that goes along
with changing wind conditions, or changing moisture conditions,
or the variability in the vegetation or the fuel.
We've been working towards replacing the Rothermel spread
equation for many years, but one of the challenges
is that the run times for this model are too slow.
Maybe that means I'm not very good at it.
I don't know. (laughs)
We began working with Google Research partners
a couple of years ago.
JOHN BURGE: The two advantages that we really bring at Google
are the large amount of compute that we
have access to, and the expertise in using it.
Mark and his team have run the model on the compute
that they have available to them, generated
about a million data points.
We were able to take Mark's model, run it
on Google's infrastructure, and we created hundreds
of millions of data points.
And then we've used that data to train up a deep neural network
to come up with an approximation for what Mark's model does
that is just much, much faster.
So Mark's model can make a fire prediction in about a minute.
Ours can make a prediction in about 20 to 30 milliseconds.
And due to how AI works, we're not
limited to just making a single prediction
at a time like Mark's model.
In that same 20 milliseconds, we can actually
make thousands of predictions.
Are these spotted, or are these--
JASON FORTHOFER: The fire behavior modeling is often
used in planning phases.
Maybe there's a community that we're trying to protect
and we want to do some kind of mechanical treatment
or a prescribed burn.
With these new modeling systems, we can simulate maybe 10,000
fires in a community under different weather and wind
conditions and different locations of where the fire
might start, and start to identify areas of high
significance.
Like, if we could change the fuel type in this area,
that would really help firefighters
when they're trying to suppress a fire.
From this new model, we'll be able to teach firefighters what
dryness does to a fire, or wind, or a change in fuel type,
because we have seen so many firefighters die on fires
when they don't anticipate what the fire's gonna do.
And there could be some huge gains from something
like FireSat, where we will get extremely good information
about how fires spread, and we can use
that to forecast fire behavior.
JULIET ROTHENBERG: People turn to Google in times of crisis
to get information about what to do next.
And that's part of the reason why
it's been so important for Google
to have wildfire boundaries as a part of Google Maps and Google
Search.
Our wildfire boundary product shows wildfire boundaries
using satellite imagery and AI.
And what's so exciting about FireSat
is that we can get a real step change in improvement
in our ability to detect fires early
and to detect small fires, which is
very important for helping people stay as safe as possible.
CHRIS VAN ARSDALE: Our hope is that FireSat
will shine a light where there wasn't one
before to really bring data to the world to make sure
that everybody has equitable access to it,
and is able to actually achieve improvements to people's health
and safety.
KATE DARGAN: We were doing a FireSat presentation back
in Washington DC, and the head of the International Association
of Fire Fighters, a Boston character,
was sitting in the audience and--
excuse me if I fumble my Boston accent--
but he said, (BOSTON ACCENT) "Do you
mean to tell me that we'll get satellites for just
the firefighters, just for us?
That's amazing.
I want that to happen."
