The HRMM working group of IRC deals with measurements and models of hyperspectral radiation used for remote sensing of atmosphere, land, and ocean.

Mission Statement

Hyperspectral radiation, as defined by this working group, is spectrally continuous radiation in the solar spectral range with a spectral resolution of a few nm or better.  Hyperspectral radiation covers the UV, visible, near-infrared and shortwave infrared.  
The aim of the HRMM working group is to bring together expertise, knowledge and people in order to facilitate and strengthen hyperspectral remote sensing and radiative transfer modelling for environmental monitoring and climate research. The HRMM is a contact point between the spectral remote sensing and modelling communities and the IRC.
The focus of HRMM is on hyperspectral retrieval methods, on the physics behind those methods, and on hyperspectral radiative transfer modelling needed to interpret hyperspectral observations, but not on the multitude of results obtained with hyperspectral remote sensing.

Key Activities

The working group will use various approaches to reach its aim, for example:

• Make inventories of methods of hyperspectral remote sensing and modelling
• Perform intercomparisons of hyperspectral radiative transfer model calculations
• Collect benchmarks for hyperspectral radiation calculations
• Perform intercomparison of hyperspectral retrieval methods; e.g. for atmospheric composition (trace gases, clouds, aerosols): DOAS, spectral fitting, eof’s etc.
• Make inventories of application areas: trace gas column densities, oxygen pressure, aerosol and cloud properties, ocean colour, vegetation properties, etc.….
• Organize workshops, stimulate publications,  foster collaborations
• Formulate recommendations
