Abstract
It is now possible to combine high spectral resolution observations (like AIRS) with moderate spatial resolution (like MODIS) in a single instrument. The ARIES instrument concept provides over 3000 spectral channels in the 0.4 - 15.4 μm spectral region with spatial resolution of 1.0 km while still scanning ±55°. The ARIES has size and mass less than half that of AIRS or MODIS primarily due to the advancements in focal plane assemblies and wide field optical systems developed under the NASA IIP and in US industry. The combined capability will allow more cloud free observations per unit area, and improve the overall cloud-clearing approach applied on AIRS. It will also improve sensitivity to atmospheric water vapor, temperature and trace gases in the boundary layer and facilitate studies of surface and atmospheric interaction for global climate studies. Improvements are expected in regional weather forecasts and hurricane prediction. This paper discusses the primary requirements for ARIES, the expected science and operational benefits and an instrument concept that demonstrates the viability and low risk of the approach.
