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 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).
The SARSense campaign in the Jülich area (Germany) in summer 2019 was performed to support the ESA Copernicus high priority mission ROSE-L.
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.
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.
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.
This campaign covers the fields of atmospheric composition: NO2, SO2, aerosols, over Romania (Bucharest and Turceni) and Germany (Berlin).
SoyFLEX II 2016
The SoyFLEX II experiment was a repetition of an experiment that took place during the 2015 campaign in Germany.
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.
SoyFLEX 2015 took place over the agricultural area around Jülich, Germany and Rzecin wetland site, Poland
During the AfriSAR 2015 campaign, shared between ONERA (dry season, July 2015) and DLR (wet season 2016), Pol-InSAR and TomoSAR airborne data set were collected over four test sites over Africa, therefore covering different forest structures.
The COMEX campaign supports the mission definition of CarbonSat and HyspIRI by providing representative airborne remote sensing data ‐ MAMAP for CarbonSat.
FLEX EU 2014
The FLEX-EU Campaign was carried out in 2014 over an agricultural area around Jülich, Germany, Latisana, Italy and forest sites in Czech Republic
In the SEN2EXP campaign, the data gap for broad leaf forests is addressed as suitable reference datasets of sufficient quality do not exist.
The primary goal of the 2013 joint ESA/NASA airborne campaign was to record an unprecedented FLEX-like dataset containing maps of sun-induced fluorescence, hyperspectral reflectance, surface temperature, and canopy structure.
NoSREx-I -II and -III
The Nordic Snow Radar Experiment (NoSREx) took place between November 2009 and May 2010. The objective of the campaign was to provide a continuous time series of active and passive microwave observations of snow cover in a representative location.
This HYFLEX campaign aimed to deliver maps of sun-induced fluorescence recorded from airborne measurements using the approaches of the spaceborne FLEX mission.
The Dutch research team ROVE (Radar Observation on Vegetation), funded by the remote sensing organization NIWARS, started in 1974 to investigate the scattering of microwaves by crops and soils, in order to help interpretation of radar imagery.
The major objectives of the experiment were the temporal survey of the variation of the measurements in time scales ranging from diurnal, weekly, monthly, up to 12 months of observation.
The BioSAR-3 (BioSAR 2010) campaign was specifically planned and implemented to investigate possibilities for a future spaceborne P-band polarimetric and interferometric SAR with a life-time of multiple years.
CoSMOS 2005, 2007, 2008, 2010
The Campaign for Validating the Operation of SMOS (coSMOS) was designed to acquire SMOS-like data so that the algorithms were fine-tuned and properly validated before the launch of SMOS mission in 2007.
