Copernicus Cal/Val Solution - D3.2 - Recommendations for R&D on Cal/Val Methods
This document presents a gap analysis of the methods used in the calibration and validation of Earth Observation satellites relevant to the Copernicus programme and suggests recommendations for the research and developments required to fulfil this gap when/where
possible.
The document identifies the gaps and limitations of the CalVal methods, used for calibration and validation (CalVal) activities for the current Copernicus missions. It will also address the development needs for future Copernicus missions. Four types of missions are covered based on the division used in the rest of the CCVS project: optical, altimetry, radar and microwave and atmospheric composition.
Finally, it will give a prioritized list of recommendations for R&D activities on the CalVal methods.
The information included is mainly collected from the deliverables of work packages 1 and 2 in the CCVS project and from the consortium experts in CalVal activities
Copernicus Cal/Val Solution - D3.1 Recommendations for R&D activities on Instrumentation Technologies
The Document identifies the gaps in instrumentation technologies for pre-flight characterisation, onboard calibration and Fiducial Reference Measurements (FRM) used for calibration and validation
(Cal/Val) activities for the current Copernicus missions. It also addresses the measurement needs for
future Copernicus missions and gives a prioritised list of recommendations for R&D activities on
instrumentation technologies.
Four types of missions are covered based on the division used in the rest of the CCVS project: optical,
altimetry, radar and microwave and atmospheric composition.
It also gives an overview of some promising instrumentation technologies in each measurement field
for FRM that could fill the gaps for requirements not yet met for the current and future Copernicus
missions and identifies the research and development (R&D) activities needed to mature these
example technologies. The Document does not provide an exhaustive list of all the new technologies
being developed but will give a few examples for each field to show what efforts are being made to fill
the gaps. None of the examples is promoted as the best possible solutions. The selection is based on
the authors' knowledge during the preparation of the Document.
The information included is mainly collected from the deliverables of work packages 1 and 2 in the
CCVS project. The new technologies are primarily from the interviews with various measurement
networks and campaigns carried out in tasks 2.4 and 2.5. Reference documents can be found in section

MERLIN : A French-German Space Lidar Mission Dedicated to Atmospheric Methane
The MEthane Remote sensing Lidar missioN (MERLIN) aims at demonstrating the spaceborne active measurement of atmospheric methane, a potent greenhouse gas, based on an Integrated Path Differential Absorption (IPDA) nadir-viewing LIght Detecting and Ranging (Lidar) instrument. MERLIN is a joint French and German space mission, with a launch currently scheduled for the timeframe 2021/22. The German Space Agency (DLR) is responsible for the payload, while the platform (MYRIADE Evolutions product line) is developed by the French Space Agency (CNES). The main scientific objective of MERLIN is the delivery of weighted atmospheric columns of methane dry-air mole fractions for all latitudes throughout the year with systematic errors small enough (Peer reviewe
