New cross-calibration readies PROBA-1 data for climate research

While PROBA-1 has already exceeded expectations by suppling over 21 years of Earth observation hyperspectral data, recent cross-calibration activities are aiming to ensure the data will robustly serve long time-series research, even when the satellite ends operations.

An overview of ESA's Third Party Missions programme

ESA’s Third Party Missions programme consists of almost 50 satellite missions, which are owned by organisations around the world. ESA has agreements with these organisations to acquire, process, and distribute data from their missions

Mission - Third Party Missions

PROBA-1

PROBA-1 is a technology demonstration satellite that later became an operational Earth observation mission.

Campaign

SPARC

ESA's SPectra bARrax Campaign (SPARC) activity was part of the preparatory study for a proposed ESA Earth Explorer mission called SPECTRA. The objective was to collect a CHRIS/PROBA reference dataset for SPECTRA-related studies.

Activity - Quality

EDAP

The ESA Earthnet Data Assessment Pilot (EDAP) project will perform assessments for various missions to ensure the delivered data is fit for purpose.
