Copernicus High Resolution Radiometer ‘Science to Operations’

Copernicus High Resolution Radiometer ‘Science to Operations’

14 January 2020 Published by

Dear All:

I trust you are well.  Please could you consider attending and disseminate the announcement for the Copernicus High Resolution Radiometer ‘Science to Operations’ meeting to your networks?  Registration and abstract submission is open at

I have provided a short abstract for the mission (now in Phase B2/C/D/E1) to stimulate your appetite.

Thank you for your help and I hope to see you at ESTEC later this year.

With my best regards


The Copernicus High Resolution Microwave Radiometer (CIMR) – what is it?

Climate change and globalisation are the dominant drivers of societal impacts in the Arctic with economic development rapidly transforming the geo-politics and the physical and biogeochemical environment of the region. For example, new prospectors are increasing their activities using modern techniques for oil and gas, fisheries and mineral resources, and commercial ship traffic is growing dramatically. Several areas of extreme concern have been recently raised by the International Panel for Climate Change. In response, the European Commission and the High Representative of the Union for Foreign Affairs and Security Policy issued to the European Parliament and the Council, on 27 April 2016, a joint communication that proposed “An integrated European Union policy for the Arctic”.

Continuously monitoring the vast and harsh Arctic environment in a changing world is considered essential to the successful implementation and effective management of the Arctic Policy. The existing Copernicus programme already offers operational thematic services to monitor the atmosphere, marine environment, land, climate change, emergency management and security. However, new high-priority requirements from key Arctic user communities have emerged that highlight the need for new satellite measurements that are not currently available as part of the Copernicus satellite fleet.

CIMR will deploy a wide-swath (>1900 km) conically scanning multi-frequency microwave radiometer.  CIMR measurements will be made using a forward scan arc followed ~260 seconds later by a second measurement of the same location using a backward scan arc.  Polarised (H and V) channels centred at 1.414, 6.925, 10.65, 18.7 and 36.5 GHz are included in the mission design under study.  The real-aperture resolution of the 6.925/10.65 GHz channels is <15 km, 5 and 4 km for the 18.7/36.5 GHz channels respectively.  The 1.414 GHz channel will have a real-aperture resolution of ~60 km (fundamentally limited by the size of the ~8m deployable mesh reflector).  However, most channels will be oversampled allowing gridded products to be generated at much better spatial resolution.

Channel NEdT is 0.2-0.8 K with an absolute radiometric accuracy goal of ~0.5K.  CIMR will fly in a dawn-dusk orbit providing, with one satellite, ~95% global coverage every day (except for rain conditions), better than daily coverage poleward of 55°N and S, and no gap in coverage at the pole itself. CIMR will operate in synergy with the EUMETSAT MetOp-SG(B) mission so that in the polar regions (>65°N and 65°S) collocated and contemporaneous measurements between CIMR and MetOp MWI/ICI and SCA measurements will be available within +/-10 minutes.

This meeting will provide an opportunity for you to contribute to the development of the CIMR mission by bridging the gap between scientific measurements and operational services based on the capability of the CIMR mission in support of Copernicus.

The objectives of the meeting are:

  1. To present the CIMR mission capability and anticipated products.
  2. To review the scientific questions that can be addressed by CIMR in support of the Arctic Policy.
  3. To review approaches to Level-2 Geophysical retrievals capitalizing on the multi-frequency measurements of CIMR to address Arctic Policy needs.
  4. To review approaches to CIMR product uncertainty derivation, product needs and application.
  5. To review global application of CIMR products in support of Copernicus Services.
  6. To provide technical input from operational services regarding CIMR products.
  7. To review validation approaches and challenges for CIMR products.

The meeting will be based on a combination of plenary sessions and discussion-group meetings and is open to anyone with an interest in the CIMR mission. Places are limited and a selection of participants will be based on a review of abstract contributions.
