PCW/PHEMOS UV-VIS Spectrometer: Air Quality from a Quasi-Geostationary Orbit
Abstract
A UV-VIS Spectrometer (UVS) is one of two atmospheric monitoring instruments being considered for PHEOS (Polar Highly Elliptical Orbit Science) as part of the weather, climate and air quality measurement suite onboard the proposed Canadian PCW (Polar Communications and Weather) satellite mission. The UVS is an imaging spectrometer that covers the spectral range 280 - 650 nm in the UV and Visible regions. It is intended to measure a number of species including O3 and NO2 at 10 × 10 km2 spatial resolution - or better - for air quality studies. The PCW two-satellite system will allow the mapping of air quality parameters on an hourly basis over most of the circumpolar area between 55 and 90N and provide substantial, partial coverage down to below 40N. This paper presents the current status of the UVS instrument and also discusses the UVS science objectives as well as the measurement characteristics. The PHEOS study was funded by the Canadian Space Agency (CSA).
