Hello All,
Well once again I am headed back to the North. I am going back to CFS Alert (where I was last may) in order to participate in in-situ measurements for CryoVEx 2011, the validation campaign of the Cryosat-2 radar altimeter. Christian Haas (my supervisor) and I will be aiding a team of researchers from the University College of London in conducting ground based measurements of snow and ice properties and validating the penetration of Ku-band microwaves through the snow to the snow/ice interface. The satellite Cryosat-2 also uses Ku-band and there is some debate of whether or not it always penetrates to the snow/ice interface. As Cryosat-2 is meant to estimate sea ice thickness by inferring the height of the sea ice above the water, if the signal doesn't penetrate to the ice surface, it will overestimate this height (called freeboard) and will report thicknesses that are greater than reality.
Yesterday I left Edmonton and flew to Yellowknife, I had a nice afternoon around Yellowknife and even got myself a brand new winter jacket at a good price (you'll see some pictures). We met up with the Environment Canada guys who we are hitching a ride from here to Resolute with this morning. We should arrive in balmy Resolute Bay (it is -33C, feels like -45C with the wind) later this afternoon.
Otherwise not alot to report, have been downloading imagery and just getting ready.
Well I should go.
Cheers
Justin
