*Abstract*

	

The seminar presents the current status of the Polar Communications and 
Weather (PCW) mission, led by the Canadian Space Agency.  As the name 
indicates the dual goal of PCW is to provide continuous communications 
and Earth observation services over the Arctic, this with a near real 
time operational mandate.  Environment Canada will take responsibility 
for the production and delivery of meteorological products. Currently in 
the middle of Phase A, the mission is planned for 2016.  The seminar 
focuses on the meteorological component.  PCW is defined by a 
constellation of two satellites in a highly elliptical 12-hour "Molniya" 
orbit with apogee at ~39,600 km and perigee at ~600 km.  The 
constellation will provide for the first time seamless observations over 
the entire circumpolar domain above 55 N.  The main meteorological 
instrument is an advanced imager with characteristics similar to those 
of the imager planned for GOES-R (2015) or Meteosat Third Generation 
(2016).  The PCW imager has 20 channels covering the spectral range 0.45 
microns to 14.4 microns, with pixel sizes ranging from 500 m to 1 km for 
visible channels to 2 km for infrared channels.  The presentation will 
cover the following elements: imager definition and applications, 
orbital characteristics, critical technology issues, production of 
simulated datasets, data assimilation and impact studies, notably in 
relation to atmospheric wind vectors, and opportunities for other 
instruments.  The international context will also be presented.  For 
example the World Meteorological Organization (WMO) is supporting the 
highly elliptical observation concept, and several countries have 
indicated a marked interest for PCW.   This interest stems from the fact 
that the mission allows extending the applications developed for 
geostationary satellites all the way to the North Pole.
