KAREN scientists report from ice sheet

The University of Leeds Centre for Polar Observation and Modelling (CPOM) lead the vital ground based field work conducted as part of the KAREN campaign which took place in October 2016. Andrew Shepherd and I (Anna Hogg)...

Ready, set, snow!

Chung-Chi Lin (ESA) & Dirk Schuettemeyer (ESA), 18 March 2013 At the end of February, teams from the Finnish Meteorological Institute (FMI), GAMMA Remote Sensing and the Swiss Avalanche Service (SLF) successfully carried out the SnowScat vertical...

SnowSAR in action!

From Alex Coccia (MetaSensing), 8 March 2013 In the last week of February, the final European SnowSAR campaign for this winter in was accomplished. The campaign falls within the AlpSAR project supporting the preparations for ESA’s CoReH2O...

Battling Arctic conditions for SnowSAR

From Chris Derksen (Environment Canada)  Inuvik, Canada Although the schedule for the final preparations was very tight, activities are proceeding well for a SnowSAR flight in Canada. Over the past week, scientists from Environment Canada have been in the field near Inuvik, in the Northwest Territories. As expected, the environment near Inuvik in December has posed some challenges – the Sun does not rise above the horizon at any point in the day, so between 11:00 and 16:00 it’s just twilight. Temperatures have been very cold, not climbing above –30°C and reaching as low as –38°C. In spite of these conditions, measurements are proceeding well – Lidar scans to determine snow depth...

Things hotting up for measuring snow mass

From Dirk (ESA), 3 December 2012 A few weeks ago we kicked off a series of campaigns to hopefully provide high-quality airborne data for the development of ESA’s CoReH2O candidate Earth Explorer mission. This mission is currently undergoing feasibility study. The campaigns are built around an airborne synthetic aperture radar (SAR) called SnowSAR, which measures in the X- and Ku-band frequencies. The instrument was developed by Metasensing NL. It is used to simulate the instrument that could be carried on the CoReH2O satellite.   The major goal of these campaigns  is to map and monitor the mass of seasonal snow over different surfaces in the Austrian Alps and in Inuvik, Canada. This is...

New CryoSat ice campaign kicks-off up north

From Malcolm (ESA), Kangerlussuaq, Greenland, 28 March After months of preparation and  hundreds or even maybe even a thousand emails, the 2012 CryoSat Validation Experiment otherwise known as ‘CryoVEx 2012’ finally kicks-off this week across the Arctic. Together with NASA colleagues and participating scientists from the USA, Canada and Europe, some remarkable airborne flights are planned later this week and early the week after. One of the highlights could come as early as tomorrow when the CryoSat satellite will pass over the Arctic Ocean from the north at about 7 km per second and pass almost directly over the Canadian military base Alert located at the northern tip of Ellesmere island. This...

NASA IceBridge – clear but bumpy over southeast G...

From Michael (NASA) Greenland ice sheet, 11 April On April 11, NASA’s IceBridge campaign finally got the clear weather necessary to fly over glaciers in southeast Greenland. Typically, this area is shrouded in cloud, but strong winds from the Greenland ice sheet can clear the cloud – but these winds and the rugged coastal topography cause a lot of air turbulence. So, with clear skies came winds of up to 70 knots, which made for a bumpy ride over the calving front of glaciers such as Gyldenlove seen here. Despite the difficult conditions we were able to survey all planned glaciers in the cloud-free area south of 65N. The amount of windblown...
