Learn about the ground-based, ship-borne, balloon-borne, and airborne campaigns and small satellite field experiments that validate orbiting ESA EO satellites and support future mission development.
CryoVex/ICESat-2 Spring 2019
The ESA Spring CryoVEx/ICESat-2 campaign 2019 was the first CryoVEx campaign since the launch of NASA ICESat-2 in September 2018, and aimed at cross-validating ESA CryoSat-2 and NASA ICESat-2 missions over sea ice and land ice in the Arctic.
CryoVEx ICESat-2 Summer 2019
The ESA CryoVEx/ICESat‐2 summer campaign 2019 is an add‐on to the campaign carried out in the spring 2019, which did not cover all the flights that were planned due to weather obstacles.
Cryovex/KAREN Antarctica 2017/18
ESA’s CryoVEx/Karen 2017‐18 campaign took place in Antarctica in from Dec 2017 to Jan 2018. The campaign was composed of an airborne and in‐situ campaign and acquired extensive data sets of scanning lidar, Ku‐ and Ka‐band nadir‐looking radar, and auxiliary imagery for validation of the ESA CryoSat‐2 satellite (Ku‐band radar altimetry) and the French‐Indian AltiKa mission (Ka‐band radar altimetry).
CryoVex KAREN 2017
The CryoVex-KAREN 2017 Campaign in the Arctic had the goal to collect unique measurements to help us better understand how sea ice is changing.
CryoVEx 2016 Spring
The CryoVEx 2016 campaign was primarily carried out to follow up on a recommendation given within ESA CryoVal Land Ice project (2014-2015), where it was found that the traditional under-flights of the CryoSat-2 satellite were inadequate.
The primary objective of the PolarGap campaign was to carry out an airborne gravity survey covering the southern polar gap of the gravity field mission GOCE, beyond the coverage of the GOCE orbit.
CryoVex KAREN 2016 Fall
The CryoVex-KAREN 2016 Fall Campaign in Ilulissat, Greenland had the goal to collect unique measurements to help us better understand how snow and ice on the Greenland ice sheet is changing over time, and help ESA design future space missions to monitor the changing climate in our polar regions.
The aim of CryoVEx Ant 2014 to 2015 was to perform altimeter measurements at a designated validation site in the vicinity of the Schirmacher Oasis, near Kohnen and Neumayer as well as in the Pine Island Glacier drainage basin.
CryoVEx ASIRAS 2014
The CryoVEx 2014 airborne campaign was conducted as two separate operational periods. The sea ice activities covering large parts of the western Arctic Ocean were planned to take place early in the season to make sure the weather was stable.
CryoVEX 2014 performed measurements over the Beaufort Sea and Arctic Ocean north of Canada (Ellesmere Island) and Greenland. Airborne surveys and ground‐based snow and ice measurements were performed.
In continuation of the CryoVEx campaign in 2011, ESA initiated a second Arctic post-launch campaign in 2012 to further calibrate and validate CryoSat data products.
CryoVEx 2010 was the first CryoSat post-launch campaign to take place. It was set up as a test campaign for the upgraded ASIRAS system.
The aims of the CryoVEx 2011 experiment, operating out of Alert base, was to study the snow and ice characteristics of Arctic sea ice and its snow cover during winter.
The aims of the CryoSat Validation Experiment (CryoVEx) 2011 was to study the snow and ice characteristics of Arctic sea ice and its snow cover.
The CryoVEx 2010/2011 Antartic campaign was carried out in Dronning Maud Land from 11 November 2010 to 20 February 2011.
The key objective of the CryoSat Validation Experiment Antarctica (CryoVExAnt) campaign is a better approximation of the error range of the elevation obtained from SAR-processed altimetric radar returns and its sensitivity to surface roughness.
The ESA CryoSat Validation Experiment, CryoVEx 2008 was carried out in April and May 2008.
Following the successful 2004, 2005 and 2006 campaigns, the CryoVEx2007 campaign took place in Svalbard from 15 to 25 April 2007.
CryoSat Validation Experiment (CryoVEx) 2006 was carried out between 18 April and 18 May 2006 in the Arctic.
CryoVex 2004 was the second combined airborne and surface campaign for the preparation of the CryoSat mission, after successful completion of CryoVex 2003 by DTU.
