National Aeronautics and V5 Goals Space Administration Jet Propulsion Laboratory V5 Goals – What we achieved California Institute of Technology Pasadena, California • Focus Team perspective – V5 is an unqualified Success Improved Tuning/Transmittance (RTA) Achieved AIRS-Only Retrieval – fall-back capability Achieved Improved emissivity and surface retrievals Partially Achieved Improved error estimation and Quality Control Achieved Retrieval of Trace Gases Achieved Level 1 Calibration Achieved General software infrastructure clean-up Achieved AIRS V5 Status: 2007-03-29 - 4

National Aeronautics and Space Administration Other Features of V5 Jet Propulsion Laboratory California Institute of Technology Pasadena, California • In addition to the Focus Team work − there were other V5 enhancements: • Level 3: Quantization and other new products • SO2 and Dust Flagging, integrated in Level 2 product • Better handling of partial granules / moon in view • Reduced File Sizes • Content of Level 2 Support and Level 3 enhanced • Transition to Linux environment code baseline • Overall, V5 is a better, more robust, more stable product AIRS V5 Status: 2007-03-29 - 5

National Aeronautics and Space Administration Review V5 Schedule – from ages gone by Jet Propulsion Laboratory California Institute of Technology Pasadena, California • The planned delivery date for V5 has been revised over time • May 2005 ST MTG – June 1,2006 Then, there was the • Sept. 2005 ST MTG – April 28, 2006 September 2006 • March 2006 ST MTG – June 30, 2006 Science Team Meeting! • Sept. 2006 ST MTG – October 30, 2006 • After Sept. 2006 ST MTG – December 2006 A p ril 28, 2006 September 2006 ST MTG A IR S VER SIO N 5 V5.0 Release Candidate Team 0 V4 Clean-Up Sub-Te a m Revival Prep for V5 D e v e lopm e nt R oa dm a p M anning - JPL Blasdell - GSFC Oliphant - JPL Hearty - JPL V4.6 - V4.x Team 2 No AM SU Additional Features I D T AIRS Only Gaiser - JPL 7 2 0 Team 4 Error Integration and S.Y.

And then … … And then National Aeronautics and Space Administration and then … Jet Propulsion Laboratory California Institute of Technology Pasadena, California The The Monster of Monster of Version 5 Version 5 rears its rears its ominous ominous head! head! AIRS V5 Status: 2007-03-29 - 7

National Aeronautics and Space Administration V5 – After the Sept 2006 Science Team Meeting Jet Propulsion Laboratory California Institute of Technology Pasadena, California • Fix JPL cloud retrieval –Type 100 fallback • Solve for LW emissivity – add new retrieval step • Update CO first guess, check validity w/RTA • CO standard product fields - bottom of atmosphere • Incorporate RTA Version 9f (Methane bias change) • Generate new error estimates • Harmonizing QA Flags / Error Estimates • H2O Saturation Water Vapor Pressure – correction • Tropopause Height – new calculation • Clear Flag to L2 STD Product • L2 using Match-Up input fails in IR-Only retrieval mode • Revert to old cloudy regression used AMSU for filtering (IR-Only retrieval option) • Ensure enough parameters exist in STD Product to reconstruct radiances • Finalizing our decision… what’s our Baseline Retrieval for V5?

National Aeronautics and Space Administration Testing Jet Propulsion Laboratory California Institute of Technology Pasadena, California • In the middle of all this… there was testing! • The AIRS Project conducted its most comprehensive testing program to date. • 48-day, then 24-day focus days, a focus month • Verification of product data fields – do they meet spec? - are they internally consistent (Do they tell the same story?) • Evaluation of all standard products - Verification - Sensibility check This is not validation , this is verification but it has been extremely useful.
