Scope of the IR Sub-Group

The scope of the IR Sub-Group was agreed to be:

• Counterpart of VIS/NIR, Microwave and UV Sub-Groups
  - For satellite instruments channels in thermal infrared
• To establish user requirements for inter-calibration
• Cooperate with instrument calibration groups
  - To communicate relevant information to the users
  - To help them understand the root cause of observed biases and develop fixes
• Review existing, or Develop new inter-calibration
  - algorithms, procedures, corrections, etc.
  - to meet these
• To define and promote calibration standards, tools and datasets, and best practices
  - Including selection of inter-calibration reference

Activities

The following Sub-Group activities were identified, with participants expressing their interest in participation:

1. GEO Imagers - Promote GEO-LEO IR products to Operational + Support & Further Development

   c) Preparation for hyperspectral IR - CMA?
2. LEO-LEO IR - Development of LEO-LEO IR products for
   a) imagers (including SBAF development) - Likun, Manik (MetopA /AVHRR), Tim, Fred ?, Fangfang, Dave S.
