Abstract
Abstract. The NEMS GFS Aerosol Component Version 2.0 (NGACv2) for global multispecies
aerosol forecast has been developed at the National Centers of Environment
Prediction (NCEP) in collaboration with the NESDIS Center for Satellite
Applications and Research (STAR), the NASA Goddard Space Flight Center
(GSFC), and the University at Albany, State University of New York (SUNYA).
This paper describes the continuous development of the NGAC system at NCEP
after the initial global dust-only forecast implementation (NGAC version 1.0,
NGACv1). With NGACv2, additional sea salt, sulfate, organic carbon, and black
carbon aerosol species were included. The smoke emissions are from the NESDIS
STAR's Global Biomass Burning Product (GBBEPx), blended from the global
biomass burning emission product from a constellation of geostationary
satellites (GBBEP-Geo) and GSFC's Quick Fire Emission Data Version 2 from a
polar-orbiting sensor (QFED2). This implementation advanced the global
aerosol forecast capability and made a step forward toward developing a
global aerosol data assimilation system. The aerosol products from this
system have been used by many applications such as for regional air quality
model lateral boundary conditions, satellite sea surface temperature (SST) physical retrievals, and
the global solar insolation estimation. Positive impacts have been seen in
these applications.
