The aerosol models
C-IFS-AER is the current pre-operational aerosol model, also for the forthcoming reanalysis
Twelve prognostic variables:• Three bins sea-salt (0.03 – 0.5 – 0.9 – 20 µm)• Three bins dust (0.03 – 0.55 – 0.9 – 20 µm)• Black carbon (hydrophylic and hydrophobic)• Organic Matter (hydrophylic and hydrophobic)• SO2 -> SO4
Main physical processes represented:
• emissions, fire emissions being interactive (with the GFAS system)• horizontal and vertical transport• vertical diffusion through turbulence• dry deposition• sedimentation• scavenging by large scale and convective precipitation• aerosol optics

C-IFS-GLOMAP is one of several model frameworks that include GLOMAP• GLOMAP-bin : original bin-resolved version in TOMCAT CTM• GLOMAP-mode: in UM-UKCA, TOMCAT CTM & ECMWF
GLOMAP has been integrated into cycle 40R3 of C-IFS and optimized since then.

Task 4.1: Assistance to ECMWF in setting up / running an aerosol alert service
• Continued aerosol alert computation few hours after IFS data become available, “Aerosol anomaly against climatology” (when ECMWF develops own system, run as backup and testing system)
• Explore needs and adapt (clean air alert, surface PM alert, long range transport alert, dust / biomass burning alert, research condition alert, solar radiation blocking event ?)
• Redefine threshold levels to achieve more true positive warnings for different alerts
• Explore impact of climatology used on alert triggering (eg test new IFS reanalysis when available)
• Explore fine scale aerosol fields from CAMS61 for PM alerts Europe, understand difference to IFS based PM alerts
• Test impact of new aerosol IFS versions on alert skill• Develop Contingency table verification (new data: aerosol type, clean air, PM)
