The gridded satellite data (stream=gfas, type=gsd) are also available hourly (e.g. gridded Aqua FRP from 1 to 2 UTC).

GFAS fire data is based on satellite observations of active fires but the system try to minimise the detection of other heat sources, such as volcanoes and gas flaring, so the system only include vegetation fires. Iceland is a special case and any 'fire' observations are filtered out to mitigate against including volcanic activity. Is it only for Iceland or other places too? If yes, we can list them? Sometimes, MODIS observations can miss any detections during special events, such as volcanic activity, possibly due to cloud cover. |

Gridded satellite variables are raw satellite data averaged and gridded to hourly 0.1 degree grid fields.
Analysis surface variables are output from the GFAS data assimilation.
