Current V5 Status
• V5 development continued into Summer 2006, responding to issues identified during last Science Team MTG • Mostly L2 – AIRS Only, Error representation and QA, minor constituents • Some Level 1B issues remained until quite recently • Level 3 programmers had to respond to Level 2 changes • We do have a better product now • The software baseline appears to be stabilizing now • With AIRS Project direction supported by your Science Team affirmation, we will move forward with our final build and delivery to the GES DISC
National Aeronautics and Space Administration Jet Propulsion Laboratory California Institute of Technology Pasadena, California
Current V5 Status
• Currently running V4.6.2 (V5 beta release candidate …. semi-hardened-concrete) • Processed all Focus Days in 3 variants (48-day cycle)
• Standard retrieval (AIRS + AMSU) • AIRS Only (NO AMSU) • GSFC Hybrid (AIRS Only retrieval, AMSU QA)
• Reaching closure: Still working some minor issues
• Mostly Level 2, one Level 1B remaining • Level 3 Support Product still in early design/coding stages (will not hold up delivery for this product)
• Important Dates: • Code freeze – through Level 2 no later than 13 October 2006 • Delivery to GES DISC (GSFC DAAC) on 30 October 2006

V6 Schedule Goals
• Provide sufficient time to develop a quality product improvement over V5. Time allocated for: • Preliminary investigations and prototyping • Development time – greater than 1 year • Testing – three months allocated for comprehensive tests • V6 Development concept is based on successful V5 Approach • AIRS Project will coordinate development • Science Team to lead/support task-oriented “Focus Teams” • JPL AIRS Team to support Science Team • JPL AIRS software team responsible integration and test • Mid-course corrections, status checks at two more Science Team meetings (Spring and Fall 2007)

V6 Milestones
• Learning from previous version development efforts, we have included sufficient time for all activities: • Preliminary investigations / prototyping – six months • Total development time – greater than 1 year • Testing – three months

V6 Science Goals
• V6 Science Goals – to be determined by the AIRS Project • Science Team input needed • Science Team collaboration desired • Research Topics: • Emissivity – land surfaces • Correction of other pathological cases over land • Additional minor constituents • … • … the choice is ours, and now we’ll talk about it.

Work Remaining Before V5 Code Freeze
•
Issues still being resolved: 1. Use of “GSFC-IR” retrieval as baseline process (MW-assisted AIRS-Only retrieval, aka, “blended”) 2. Implement GFS ½ degree data
• • GFS upgrade planned in next few months, date not firm Decision to:
• Integrate as ½ degree data source
– or – • Degrade back to 1 degree resolution
• This is not critical to resolve immediately. There will be at least a six-month overlap in GFS coverage. The upgrade can be delivered as a patch. However, we’d like to deliver it with the V5 delivery.

• Still Investigating • Warmest FOV, warmer than clear in Cloud-Clearing (NOAA)
• This is not a small issue and has just been identified. It will probably be resolved during the V6 development cycle.
