RAQMS

Real-time Air Quality Modeling System

Overview

The Real-time Air Quality Modeling System (RAQMS)  is a unified (stratosphere-troposphere) online global chemical and aerosol assimilation/forecasting system that has been used to support NASA, NOAA, DOE, and NSF airborne field missions, develop capabilities for assimilating satellite trace gas retrievals, and assess the impact of global chemical analyses on regional air quality predictions. RAQMS assimilates near-real-time (NRT) stratospheric ozone profiles from the Microwave Limb Sounder (MLS) and total column ozone from the Ozone Monitoring Instrument (OMI) onboard the NASA Aura satellite. RAQMS also assimilates NRT aerosol optical depth (AOD) from the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument onboard the NASA Terra and Aqua satellites.
