Abstract: The Barcelona Supercomputing Center (BSC) does
research on atmospheric chemistry, mineral dust transport and air
quality. The center is working on the development of a chemical weather
forecasting system based on the NCEP/NMMB multiscale meteorological
model, namely NMMB/BSC Chemical Transport Model (NMMB/BSC-CTM). A
gas-phase chemistry module and a multi-component aerosol scheme have
been coupled online with NMMB.
This talk will overview the
status of development of the system, the efforts done on the evaluation
of the different modules (gas and aerosol components mineral dust,
black carbon, organic matter, sulfate and volcanic ash), and its
application as a research forecast tool. The system is being enhanced
with a data assimilation system of satellite products of aerosol
optical depth. Initial efforts are focused on mineral dust only. An
ensemble Kalman filter technique (namely the Local Ensemble Transform
Kalman Filter - LETKF) has been utilized to statistically combine model
background and satellite retrievals. Currently, NMMB/BSC-CTM is
providing mineral dust forecasts with its regional configuration for
the Barcelona Dust Forecast Center (BDFC) and the Northern
Africa-Middle East-Europe (NA-ME-E) Node of the Sand and Dust Strom
Warning Advisory and Assessment System (SDS-WAS) of the World
Meteorological Organization (WMO).
All this work is done in the
framework of Spanish national research projects (Sever-Ochoa program of
the Government of Spain and national projects of the Ministry of
Economy and Competitiveness).
