IceBridge Data Access Portal
First release June 2011 with access to flight lines and flight reports
Frequent iterative releases for access to instrument data and value-added products
Additional features will be user-driven

Value-Added Products: Goals
-Process flight data to extract and
calculate useful parameters for
faster analysis
-Update compiled gridded data sets
(DEMs, bedrock elevation maps)
rapidly
-Facilitate the integration of new
science algorithms into routine
data distribution
Two classes of Products:
Along-Track Products – flightline tables of multiple sensor values and
images, and multi-sensor derived values
Gridded Products – post-campaign rapid updating of surface elevation
DEMs, dH/dt grids, and bed elevation

Along-track product examples: Surface Properties Table
-Aligned (time and location) data sets, and pre-calculated parameters
–All these data sets and derived parameters are co-located–
