In 2006, we began a three-year project funded by the NASA Integrated Decisions Support program to develop a three-dimensional air quality system (3D-AQS). The focus of 3D-AQS is on the integration of aerosol-related NASA Earth Science Data into key air quality decision support systems used for air quality management, forecasting, and public health tracking. These will include the U.S. Environmental Protection Agency (EPA)'s Air Quality System/AirQuest and AIRNow, Infusing satellite Data into Environmental Applications (IDEA) product, U.S. Air Quality weblog (Smog Blog) and the Regional East Atmospheric Lidar Mesonet (REALM). The project will result in greater accessibility of satellite and lidar datasets that, when used in conjunction with the ground-based particulate matter monitors, will enable monitoring across horizontal and vertical dimensions. Monitoring in multiple dimensions will enhance the air quality community's ability to monitor and forecast the geospatial extent and transboundary transport of air pollutants, particularly fine particulate matter. This paper describes the concept of this multisensor system and gives current examples of the types of products that will result from it.
With increased spectral, spatial, and temporal resolution, the Hyperspectral Environmental Suite (HES) of the Geostationary Operational Environmental Satellite (GOES)-R Series will contribute to a significant improvement in the GOES products, including an increase in the number of products over the current GOES Imager and Sounder, especially when combined with the GOES-R Advanced Baseline Imager (ABI). The planned capabilities of the HES are encompassed by tasks, which describe required performance for operating at required scan rates. The scheduling of the HES will be determined by NOAA (National Oceanic and Atmospheric Administration). A range of possible scan scenarios for optimizing the collection of data for users with a variety of geographic or phenomenological concerns will be discussed here. One such schedule from the sounding capability of the HES would be a full "sounding disk" at 10 km (sub-satellite point resolution) covered every three hours, as well as the contiguous U.S. every hour at 4 km resolution, plus selected other regions of interest. The HES Coastal Waters (CW) will provide coverage of the coastal areas every three hours, in addition to other regions such as the Great Lakes, or other features of interest.
