CIMR Mission Requirements Document v5

By TomLav | March 28, 2023 - 09:39

This is the official fifth release of the CIMR Mission Requirements Document (MRD v5), prepared by ESA, including contributions of the Mission Advisory Group.

The MRD is a key reference document for the CIMR mission.

It is accessible from https://esamultimedia.esa.int/docs/EarthObservation/CIMR-MRD-v5.0-20230211_(Issued).pdf

CIMR Figures

Sensitivities to ocean and sea ice parameters as a function of CIMR channels

The figure illustrates the sensitivities of the low passive microwave brightness temperature at the top-of-the-atmosphere, in terms of Sea Surface Temperature (SST), Sea Surface Salinity (SSS), Ocean Wind Speed (OWS) and Sea Ice Concentration (SIC) as a function of frequency from 1 to 40 GHz, range that is covered by the CIMR MRC channels.

CIMR brings continuity to L-band radiometry constellation

The diagram illustrates the three first satellite missions designed to measure the radiation emitted from the Earth at L-band (ESA's SMOS, NASA/CONAE Aquarius/SAC-D and NASA SMAP) and their continuation through the candidate mission Copernicus Imaging Microwave Radiometer (CIMR).

Simulating CIMR resolution at the sea-ice edge

The figure shows the simulated CIMR sea ice concentration field. The sea ice concentration is computed using the Bristol algorithm as an example, applied on simulated brightness temperatures at the resolution of CIMR.

Daily coverage of CIMR (Arctic, Antarctic, and Global views)

The CIMR mission is specifically designed to ensure sub-daily coverage everywhere in the Arctic region, so as to support the Integrated EU Arctic Policy. Particularly, CIMR will achieve full sub-daily coverage of the Arctic Ocean and adjacent seas (including "no hole at the pole").

Scanning Geometry of the CIMR instrument

Scanning geometry of the Copernicus Imaging Microwave Radiometer (CIMR) instrument. Forward and backward scans are a unique feature of the mission.

Daily Coverage of Sentinel-1 satellites

These maps combine the daily (24h) Synthetic Apperture Radar (SAR) Arctic coverage of Copernicus Sentinel-1 A and B satellites (orange), with unique ship visits 2009-2016 in the Arctic (blue-yellow).

AMSR-E/2 and SMOS Brightness Temperatures by Surface Types

Average top of atmosphere brightness temperatures (Tbs) and standard deviations of Arctic open water, first-year and multiyear sea ice at typical imaging frequencies between L-band (1.4 GHz) and W-band (89 GHz).

Satellite SST : IR vs. CIMR coverage

With Arctic sea ice retreating, Sea Surface Temperature (SST) is an increasingly important parameter to observe. Infrared (IR) sensors, such as Sentinel-3 SLSTR are blocked by clouds. Being an advanced Passive Microwave instrumnent, CIMR will measure SST through clouds at 15 km resolution.

CIMR compared to other PMRs

The diagram illustrates the frequency channels of the candidate Copernicus Imaging Microwave Radiometer (CIMR) mission, and their targeted spatial resolutions. CIMR is also compared to two other similar Passive Microwave Radiometers (PMR): the Japanese AMSR2 in orbit since 2012, and the MWI to fly on-board the European EPS-SG satellites from ~2023 (MWI-SG). Also, the resolution of the planned L-band channel is compared to NASA SMAP, and ESA SMOS.
