NEW DATA PORTAL FOR FLOW VELOCITIES OF GREENLAND OUTLET GLACIERS FROM
LANDSAT IMAGERY 1972 – 2015
Herewith we like to announce the release of a new data portal that
enables to access flow-velocity fields for more than 300 outlet glaciers
along the margin of the Greenland ice sheet.
It is for the very first time that for many Greenland glaciers flow
velocities can be tracked back to 1972.
The new web-based portal can be reached at
https://data1.geo.tu-dresden.de/flow_velocity.
It enables to investigate the temporal evolution of the glacier flow
velocity in many different ways such as along freely selectable profiles
or in terms of time series for discrete points.
So far, we included more than 37,000 optical multi-sensoral scenes from
Landsat 1 to 8. More than 100,000 flow-velocity fields for more than 300
Greenland glaciers have been processed for the time period until 2012.
For the subsequent years until 2015 we analyzed the flow-velocity fields
for the fastest flowing glaciers. The processing is still ongoing while
incorporating new recordings of Landsat 7 and 8 as well as further
scenes made available by the Landsat Global Archive Consolidation effort.
The processed data can be downloaded and freely used after a short
registration. For reference we like to ask you to refer to our paper
published in 2015.

Any feedback is very much welcome.
