MDR Background

• Feasibility study 2002, after Call for ideas by
  Swedish National Space Board
• STEAM recommended by Scientific Research Advisory
  Committee to SNSB, February 2003
• STEAM promoted in SNSB research strategy,
  November 2003
• Phase A1 coordinated by SSC, pending a funding
  decision for total phase A

4
MDR Objectives

• Review the scientific objectives of STEAM, as
  presented in the Scientific Document and during
  the review
• Define the mission as an input to further phase A
  study of instruments and system

Review Board

• Review Board consists of
• Nils Gustafsson
• Alain Hauchecorne
• Nik Kämpfer
• Gordon Peckham (chair)
• Michiel van Weele

Review Board Guidelines 1(2)

• Subject matter Scientific objectives of
  affordable mission
• Questions
• Is previous experience well used in the present
  STEAM definition?
• In particular for the radiometer
• Right species, frequency range, and resolution
  chosen?
• Aim for lower resolution but cover more species?
• Does ozone monitoring demand a 500 GHz band?
• Is a nadir channel imperative?

7
Review Board Guidelines 2(2)

• In particular, for the near-optical instrument
• Right species, frequencies, and concept for
  supporting the radiometer?
• Are there other urgent needs for this instrument?
• Given other planned missions, should we let go of
  ozone monitoring and concentrate on UTLS?
• Do you have suggestions for calibration and
  validation methods?
• Should STEAM aim to be a precursor test of near
  real-time data?
• How does the STEAM mission fit with the overall
  European strategy?
