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.
The overall objective of the SnowLab-NG activity was to provide a comprehensive multi-frequency, multi-polarisation, multi-temporal dataset and active and passive microwave measurements over snow-covered grounds.
The “WaddenSAR – Airborne bistatic C-band SAR experiment to demonstrate different acquisition geometries” was initiated to support the development of the Earth Explorer 10 Harmony mission.
The main objective of HydroSoil was to demonstrate the retrieval of soil moisture and vegetation parameters in an agricultural field under controlled conditions using a ground-based fully-polarimetric SAR instrument (GB-PolSAR).
As part of the detailed design and feasibility studies of the Sea Surface Kinematics Multiscale (SKIM) 9th Earth Explorer program candidate mission, ESA initiated the Drift4SKIM field campaign, with the aim to evaluate the feasibility of measuring the insitu Total Surface Current Velocity (TSCV) using pulse-pair Doppler radars.
The SnowSum experiment is designed to support the development of future concepts to monitor the cryosphere.
The aim of the SnowLab campaign was to provide a comprehensive multi-frequency, multi-polarisation, multi-temporal dataset of active and passive microwave measurements over snow-covered grounds to investigate the relationship between effective snow and ground parameters and the resultant signals detected by microwave radars and radiometers.
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.
The SARSense campaign in the Jülich area (Germany) in summer 2019 was performed to support the ESA Copernicus high priority mission ROSE-L.
In preparation of the Earth Explorer 9 FORUM mission, a new facility named FIRMOS (Far-Infrared Radiation Mobile Observation System) has been developed for field applications from both ground-based and airborne platforms to check with real measurements the sounding capability provided by FIR observations.
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.
The main objective of “SARSimHT – Airborne SAR experiment to simulate Hydroterra data” was to demonstrate the image formation process of Hydroterra through the exploitation of a repeat-pass hyper-temporal airborne SAR image stack acquired over short time intervals representative of the Hydroterra mission.
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).
The BelSAR project intended to carry out an airborne campaign for SAR bistatic interferometric measurements at L-band and full polarization, over a test site in Belgium.
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.
The main objective of “BorealScat – Technical Assistance for the Deployment of a Tower-based Radar and Geophysical Measurements during the BorealScat Experiment” was to characterise and quantify the temporal variations of radar observations of a forest stand over timescales ranging from seconds to years and to investigate the effects of environmental variables.
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.
This campaign covers the fields of atmospheric composition: NO2, SO2, aerosols, over Romania (Bucharest and Turceni) and Germany (Berlin).
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.
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.
In order to further support the BIOMASS mission development, especially concerning the mission concept verification and the development of geophysical algorithms, ESA funded the AfriSAR campaign.
