Description: Singular system for both trace gas and aerosol observations, leveraging new and available technologies to miniaturize and automate operations. Improved radiometric stability Satellite calibration and validation

Benefits: Primary NASA applications include satellite calibration and validation (cal/val) activities (PACE, TEMPO, GEMS). Algorithm development and model assimilation studies would all benefit from a successful Pandora-C instrument network that addresses the short-comings of Cimel and Pandora would achieve greater accuracy in a more cost-effective manner.

Applications and customers include the US EPA, state environmental agencies, universities, and international agencies and universities. Air and water quality regulatory compliance, air quality model validation studies, and transport studies. NOAA fresh water, coastal ocean, and blue water studies would benefit from this system.
