Known issue with anomalous FRP (and emissions flux) values associated with |
| 11 |
false Aqua MODIS detection at high latitudes over the eastern Arctic for |
| 12 |
the period 9-14 August 2024. Watch the Forum announcement for updates. |

We are aware of an issue with our Global Fire Assimilation System (GFAS) |
| 25 |
outputs at high latitudes over the eastern Arctic due to some contaminated |
| 26 |
Fire Radiative Power observations on 9 August 2024 and causing an area of |
| 27 |
unrealistic estimated in fire emissions in region. This is also affecting |
| 28 |
the CAMS global atmospheric composition forecasts (e.g. development of |
| 29 |
unrealistic/false plumes of AOD, CO, PM2.5 and GHGs) across the eastern |
| 30 |
Arctic region and some care is currently required in their use. |
| 31 |
|
| 32 |
We are monitoring the situation closely and will share more information |
| 33 |
with you when it becomes available. |
