Can remote sensing detect forest fires?

Forest fire monitoring by remote sensing can be achieved through the use of polar- orbiting and geostationary satellites. The application of these satellites is limited by their temporal resolutions. Their low temporal resolution makes them unable to detect active fires as near real-time as possible.

How do satellites detect forest fires?

Since several years ago, satellites have been used to detect fires. The thermal band of MODIS has a 1,000 meters resolution per pixel whereas VIIRS has a 375 meters resolution per pixel. This higher resolution enables VIIRS to detect fires that MODIS overlooks.

Can satellites detect wildfire?

Satellites allow for detecting and monitoring a range of fires, providing information about the location, duration, size, temperature, and power output of those fires that would otherwise be unavailable. Satellite data is also critical for observing and monitoring smoke from the fires.

Which satellite data is used in forest fire monitoring?

The forest fire detection and monitoring system uses satellite data from the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Terra and Aqua satellites, whose data can be used to track changes in landscape over time.

How does remote sensing detect fire?

Actively burning fires can be detected using thermal infrared bands (3.6–12 µm range) from coarse spatial resolution sensors such as the Advanced Very High Resolution Radiometer (AVHRR), the Along Track Scanning Radiometer (ATSR), or the Moderate Resolution Imaging Spectroradiometer (MODIS).

Which satellite sensor is used for active fire detection?

In the last few years (2013), the new generation medium resolution imager, the VIIRS (Visible Infrared Imaging Radiometer Suite) satellite sensor, has been used to detect active fires, also.

Can satellites start fires?

That ignition does not go completely unnoticed. New weather satellites also play a critical role in spotting wildfires. He said a satellite can detect a very small fire just minutes after it starts.

What can satellites detect?

Satellite sensors can detect light that we can’t see. The electromagnetic energy reflects off the Earth’s surface and up to the satellite sensor, which collects and records information about that energy. That information is transmitted to a receiving station in the form of data that are processed into an image.

Which satellite is used in disaster management?

Satellites for Disaster Management Applications

Why forest fire detection is important?

Millions of hectares of forest are destroyed by fire every year. Monitoring of the potential risk areas and an early detection of fire can significantly shorten the reaction time and also reduce the potential damage as well as the cost of fire fighting.

What do remote sensing systems measure?

Remote sensing is the process of detecting and monitoring the physical characteristics of an area by measuring its reflected and emitted radiation at a distance (typically from satellite or aircraft). Special cameras collect remotely sensed images, which help researchers “sense” things about the Earth.

What is active fire detection?

Active fire protection requires action to be taken to detect and alert, stop or contain a fire. This may involve a person taking a manual action, such as using a portable fire extinguisher. On the other hand, this may be a smoke detector that triggers an alarm or automatic sprinkler.

How are satellites used to monitor forest fires?

Optical remote sensing tools utilize the visible and infrared sensors located on high-resolution earth observation satellites for studying forest fires. The near-infrared, mid-infrared and thermal bands are susceptible to changes in vegetation health.

How is remote sensing used in forest fires?

Remote sensing techniques are a useful tool in order to generate maps showing different degrees of damage affecting vegetation after a large wildfire in an effective manner. Objective of these severity maps is to locate priority intervention areas and plan forest restoration works.

How are sensor data used in wildfires?

Scientists see that wildfires can be complex in that they incorporate a variety of factors that include temperature, wind, fuel, and other future weather conditions. Sensor data could be used to directly feed simulations that then attempt to forecast change in a fire.

How is Earth observation used to study fires?

The energy dissipated by features located on the Earth’s surface has unique characteristics. These spectral signatures allow us to examine a wide variety of terrestrial processes. Optical remote sensing tools utilize the visible and infrared sensors located on high-resolution earth observation satellites for studying forest fires.
