PCW/PHEOS-WCA: QUASI-GEOSTATIONARY VIEWING OF THE ARCTIC AND ENVIRONS FOR WEATHER, CLIMATE AND AIR QUALITY

摘要

The Polar Communications and Weather missionrnproposes to use two satellites each in a highly eccentricrnorbit with apogee ～ 42,000 km and a period in the 12-rn24 hour range in order to have quasi-stationary 24x7rnviewing over the Arctic. The baseline operationalrnmeteorological instrument is a 21-channel spectralrnimager similar to MODIS. The CSA is also exploringrnthe possibility of a suite of innovative vertical soundingrnFTS and UVS science instruments with an imagingrncapacity for Arctic and mid-latitude weather, climaternand air quality science. We report on the outcome of arnPhase A study completed in March 2012 conducted byrnABB, COM DEV and the Science team, a group ofrnatmospheric scientists from university and governmentrnwith international collaborators.
