GRWG Web Meeting: Best Practice for defining SBAFs
- Tim Hewison (EUMETSAT) - Introduction
- Ben Scarino (NASA) - NASA SBAF web page
- Tom Stone (USGS) How ROLO accounts for different Spectral Response Functions
- Sebastien Wagner (EUMETSAT) - Example SBAFs derived from GIRO
- Tim for Viju John (Met Office) - Meteosat-HIRS SBAFs
- Ben Scarino (NASA) - The use of IASI to define SBAFs for IR channels
- All - Discussion: Can we recommend a standard procedure to define SBAFs and their uncertainties?
Chair: Tim Hewison

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.
