Following on from the expedition to Greenland at the end of 2016 as part of an international effort to develop new space technology to monitor our changing polar environment, a new field campaign is underway in Antarctica.
Tânia Casal, ESA Earth Observation Campaign Coordinator, is currently on her way to join the team in Antarctica and sends her first blog on the campaign:
Punta Arenas, Chile. (T. Casal)
This is our first CryoVEX/KAREN campaign in Antarctica. ESA’s CryoSat delivers vital information about how the thickness of Earth’s ice is changing. To do this, the satellite carries a radar altimeter, but now we want to find out if an altimeter that works using two wavelengths would provide even better information.
The campaign involves taking measurements from aircraft and on the ice to compare with measurements from CryoSat and from the French-Indian AltiKa mission. The two satellites both carry radar altimeters, but use different bands. CryoSat uses the Ku-band (around 2.2 cm) and AltiKa uses the Ka-band (around 8 mm).
We need to understand how a two-wavelength radar altimeter could offer continuity and improve the current single-wavelength measurements provided by CryoSat
The campaign involves collecting airborne and in-situ measurements to see how ...
