GRWG Web Meeting: Best Practice for defining SBAFs


  1. Tim Hewison (EUMETSAT) - Introduction
  2. Ben Scarino (NASA) - NASA SBAF web page
  3. Tom Stone (USGS) – How ROLO accounts for different Spectral Response Functions
  4. Sebastien Wagner (EUMETSAT) - Example SBAFs derived from GIRO
  5. Tim for Viju John (Met Office) - Meteosat-HIRS SBAFs
  6. Ben Scarino (NASA) - The use of IASI to define SBAFs for IR channels
  7. All - Discussion: Can we recommend a standard procedure to define SBAFs and their uncertainties?

Chair: Tim Hewison

EUMETSAT: Sebastien Wagner, Bartolomeo Viticchie

JMA: Arata Okuyama, Masaya Takahashi

KMA: Dohyeong Kim

NASA: Ben Scarino, Dave Doelling, Amit Angal

NOAA: Fangfang Yu

USGS: Tom Stone


Action: Ben Scarino, Tom Stone and Bart Viticchie to scope the potential of integrating the GSICS Lunar Observation Database in the NASA SBAF tool - by 2016 GRWG/GDWG meeting.

Action: Dave Doelling and Ben Scarino to draft requirements for SBAFs and circulate to GSICS developers mailing list for review - by end December 2015.

Action: Masaya Takahashi, Arata Okuyama, Sebastien Wagner, Viju John and Tim Hewison to review SBAF requirements and work with Dave Doelling and Ben Scarino to start drafting a best practice process to define SBAF - by 2016 GRWG/GDWG meeting.

Recommendation: Ben Scarino to consider applying JMA's "constrained optimization" gap-filling method to extrapolate IASI radiances to cover the shorter wave part of SWIR channels.

Recommendation: Ben Scarino to investigate hypbrid approach of linear regression of results of piece-wise comparisons to provide unweighted coverage over full dynamic range.
