1. AMPS DMSP WMC CReSIS IREP Program at Univ. of Tasmania - Dan Steinhoff
Analyze position and intensity of weather systems impacting East Antarctica over time period leading up to and during large precipitation events
Compare AMPS precipitation with AWS sonic altimetry accumulation
AMPS captures events well
High winds and model representation of topography cause issues
Accumulation is episodic - slight discrepancies in storm track lead to large model errors

2. Annual Variation in Passive-Microwave-Derived Melt duration
These plots show 14 years of melt- duration-days and their variation with elevation for Greenland glaciers. Although many of these glaciers have accelerated, there are no strong trends in the data.

3. May 2006 GISMO Flight, 150 MHz, InSAR Swath Measurements of Topography
Beneath the Greenland Ice Sheet
Basal topography measured along a 25 km flight line and across a 3 km swath over the western Greenland Ice Sheet in May Thickness was measured using an airborne 150 MHz Synthetic Aperture Radar. The data were processed to simultaneously image the left and right sides of the aircraft. Thickness was subtracted from ICEsat surface elevation data to compute basal topography.

4. Global Interagency IPY Polar Snapshot Year:
GIIPSY
Use the international constellation of remote sensing satellites to acquire ‘snapshots’ of the Arctic and Antarctic.
Use these snapshots as gauges for comparing past and future environmental changes.
In the spirit of the IGY, secure these data sets as our legacy to the next generations of polar scientists.
Global Interagency IPY Polar Snapshot Year:
Participating International Agencies: NSF, NASA, NOAA, ESA, DLR, EUMETSAT, CSA, CMA, ROSHYDROMET, WMO, WCRP-CLiC
