1 km resolution satellite data for global hot spot monitoring, derived from FY-3A VIRR instrument channels. The product identifies high-temperature targets by analyzing mid-infrared and other spectral channels to filter solar radiation effects. It is produced by the SCIOPS organization.
Use Cases
- Detecting wildfire locations by analyzing sub-pixel hot spot intensity and temperature from infrared channel data.
- Filtering false positives in fire detection by using spectral characteristics of clouds, water bodies, and vegetation from multiple VIRR channels.
- Mapping global fire activity by utilizing the 1 km resolution hot spot information with associated reliability marks.
Strengths
- Global spatial coverage for monitoring.
- 1 km spatial resolution for hot spot identification.
- Uses multiple spectral channels to reduce solar radiation influence.
