Description
This layer shows a live feed of the latest Active Fire Data from the Moderate Resolution Imaging Spectroradiometer (MODIS) for the last 24 hours. Brightness of the data is indicated by color-change from red to yellow.
Latency - defined as time since satellite observation and the data being available in FIRMS: within 3 hours for global data.
The MODIS Fire and Thermal Anomalies layer shows active fire detections and thermal anomalies, such as volcanoes, and gas flares. Fires can be set naturally, such as by lightning, or by humans, whether intentionally or accidentally. The fire layer is useful for studying the spatial and temporal distribution of fire, to locate persistent hot spots such as volcanoes and gas flares, to locate the source of air pollution from smoke that may have adverse human health impacts.
The MODIS Fire and Thermal Anomalies product is available from the Terra (MOD14) and Aqua (MYD14) satellites as well as a combined Terra and Aqua (MCD14) satellite product. The sensor resolution is 1 km, and the temporal resolution is daily. The thermal anomalies are represented as red points (approximate center of a 1 km pixel). Terra's orbit around the Earth is timed so that it passes from north to south across the equator in the morning, while Aqua passes south to north over the equator in the afternoon.
This Map Layer is a Vector Layer composed of Points, but the Style for these cannot be changed.
