Developments by TNO for Small Atmospheric Chemistry Space Instruments: Current Status and Future Prospects

As both possible adjuncts to institutional atmospheric chemistry remote sensing missions (e.g. Sentinel 5) and as state of the art instruments in their own right, TNO has developed an all reflective instrument design to cover UV to SWIR wavelengths. An initial breadboard development (Spectrolite) has been designed to target urban atmospheric pollution with a design for a high spatial ( 1x1 km²) at 700km altitude, and similar radiometric detection capability as current instruments. The Spectrolite instrument has been flown in an airborne campaign (Aromapex, April 2016) and, given limitations in COTS elements used, has demonstrated the performance to confirm that this design approach will achieve the expected performance for an in orbit instrument. The success of Spectrolite leads the way for other future instruments aimed at applications for land and water remote sensing.
