EOS environmental remote sensing systems can provide near-continuous monitoring of the earth
The GEOSS "system-of-systems” of remote and ground-based sensors and monitoring activities will enable unprecedented access to and use of earth resources data and information

• Local & Global Long -Range Prediction of Pollutants
CMAQ (Community Mulit -Scale Air Quality modeling system)
• Reduce lung -related diseases & premature death
• Reduce hospital admissions & use of medicines
• Reduce lost workdays and schooldays
• Improve visibility and reduce haze for tourism
• Improve resiliency of crops; increase yields
• Increase confidence in government
• Improve crop estimates
• Sensitive populations can change activities
• Improve global awareness/actions of global transport
AQI (Air Quality Index)
• Assess emissions control strategies and develop SIPs(State Implementation Plan)
• Assess compliance
• Waivers to air standards
• Quantify voluntary stationary emission reductions
• Forecast transport of dust/pollutants
• Actions to reduce source emissions
• PM 2.5 forecasts
Air Quality
• Total Aerosol Amount
• Aerosol Properties
• Atmospheric Temperature
• Total Column Ozone
• Ozone Vertical Profile
• Ozone & Precursors
• Land Cover/Use
• Cloud Particles & Properties
• Cloud System Structure
• Surface Trace Gas Concentration
• Trace Gas Source
• Incorporate hemispheric transport into regional air quality decision making
