CEOS Instrument: Polar Highly Elliptical Molniya Orbit Science Weather, Climate & Air Quality Mission




Instrument:PCW PHEMOS-Atmospheric
Agency: CSA
Missions: PCW-1
 PCW-2
Status:Proposed
Type:High-resolution nadir-scanning IR spectrometer
Description:Complement PCW operational numerical weather prediction. Will also collect information about atmospheric gaseous and aerosol composition to better understand transport and climate processes.
Spatial Resolution: 10x10km
Swath Width: Field of View is 560 x 560km. Field of Regard is 3024 x 3530km.
Wavebands: 4 non-continuous bands from 0.758 to 14.3um at a spectral sampling of 0.25cm-1.
Technology: High-resolution nadir-scanning IR spectrometer
Description: Spectrometer operating in MWIR and TIR with spectral resolution typically around 0.01 % required for atmospheric chemistry. Earth viewing so as to measure vertical profiles and total columns in cloud-free or partially cloudy areas. Cross-nadir scanning for vertical profiling and total-columns. Many thousands of channels. Spatial resolution typically 5-10 km horizontal, ~ 1 km vertical (referred to the retrieved profiles). Applicable only in LEO.
