- _Parameters_:  Winds, temperature, pressure,                                                         moisture, air chemistry, reflectivity, aerosols, biology, ....

## What is IUOS?Objectives

- IUOS solution characteristics – Future IUOS will be:
- Adaptable, extensible, stable, continuous, and quality assured
- Cost-effective – avoid unnecessary duplication
- Serving multi-purposes - including driving Earth-system models
- Consistent with/component of USGEO and GEOSS

- Final Operating Capability:
- “Optimal” mix of NOAA                                                                        and non-NOAA observation                                                        platforms including both* *in situ*                                                                        and *remote sensors based on NOSA Architecture Principles

## IUOS RoadmapPhased Approach

- Incorporate Data Management Principles

## IUOS Phase 1:  Regional In Situ SoundingsRadiosonde/WV Aircraft Obs

-  In FY06-07:
- Evaluate model response to water-vapor sensor derived data
- Evaluate implications of
- forecasters using different data source and,
*reaction of broader US weather enterprise.*
- Use evaluation to develop plan for implementation
-  In FY08: Begin eliminating redundant capability for weather observations

## Phase 1:  Adaptive Sounding Strategy Notional Plan

- Use alternative sounding from commercial aircraft if WV instrumented aircraft has a scheduled ascent or descent at an airport which is within:
- XX miles of radiosonde site
- YY minutes of radiosonde valid time
- CONOPS:
- Lead Meteorologist at closest WFO coordinates sounding strategy
- Short (<3 hrs) and long term (6 month) public notices disseminated indicating product availability and associated WMO Heading and circuits
- Soundings from aircraft publicly available in near real-time
- Alternative sounding strategy limited to:
- 1 of 2 sounding launches per radiosonde station (initially)
- CONUS Non-GUAN stations
- Outcomes:
- $4M/yr in cost avoidance from radiosonde expendables
- Redundant observations eliminated
**Greater % of Data Requirements Achieved**

## Adaptive Sounding Strategy:   Assessment Timeline

-  FY06-Q3:   Statement of Need and Draft Project Plan generated (completed)
-  FY06-Q4:   Draft CONOPS Outline, Operational Requirements Document, demonstration design, and evaluation plans for model, operational forecasters, comment from US Weather Enterprise community.
-  FY07-Q2-Q4:  Site Demonstration, Test, and Evaluation (DT/E)
-  FY07-Q2:  Nowcasting and Model Impact Assessment, Community Feedback
-  FY07-Q4 to FY08-Q1:  Operational Test and Assessment  (OT/E)
-  FY08-Q2:  Initial Operating Capacity (IOC) for redundant radiosonde reduction (aka “adaptive radiosonde launch strategy”)
-  FY12:  Full Operating Capacity (FOC)

## Adaptive Sounding Strategy:   Weather Enterprise Input

- _A few questions... _
-  How do you currently use radiosonde observations?
-  What do you know about atmospheric observations from commercial aircraft?
-  What transition issues might you have with use of aircraft observations as an alternative to radiosonde observations?
-  How can NOAA best communication data quality issues associated with aircraft observations?
-  How does the proposed adaptive sounding strategy timeline impact you?
* **How can we recruit Weather Enterprise contacts to answer these and other issues associated with the Adaptive Sounding Strategy???*

## Future Directions: Radiosonde Program

**Now:  ****Radiosondes launched by the clock, 00 UTC and 12 UTC**
**Future:****  Launched as needed to best support NOAA mission, including**
**Co-incident launches to calibrate satellite observations**
**More special launches in support of high impact weather prediction**
**Launches timed to best describe diurnal solar impact for climate monitoring **
**Now:****  Observation quality useful for operational weather prediction**
**Future:****  Observation quality enhanced to better support climate monitoring**
**Now:****  Limited geo-physical parameters collected (wind/temperature/RH)**
**Future:****  Enhanced data collection (cloud properties, ozone, etc).**
_**Bottom Line:**_
**Capability to launch radiosondes will be maintained**
**Combination of observations from radiosonde, commercial aircraft, wind profilers, and other systems will result in a far greater amount of publicly available data than currently available**
***NOAA is committed to maintaining the Radiosonde Program as a key component of IUOS ***

## Future Directions: Commercial Aircraft Observations

**25 WVSSII sensors on United Parcel Service B-757 aircraft since March 2005 (NOAA) **
**60 TAMDAR sensors on Mesaba Saab 340 Aircraft since January 2005 (NASA)**
**1-2 Months:  NOAA RFP for Water Vapor Data from Commercial Aircraft **
**FY07-08:  NOAA Phase I contract for sensor installation and data collection**
**FY08-12:  NOAA Phase II contract for expanded sensor installation and data collection**
_**Bottom Line:**_
**Potential for significant increase in atmospheric soundings from regional and larger airports; ex. Each Southwest Airlines has 450 B-737s, each aircraft has about 8 destinations per day or 16 soundings opportunities**
**Expansion of parameters from aircraft include water vapor, turbulence (EDR), and icing.  Some proto-typing effort for air quality measurements (European MOZAIC Program)**
**Enhanced data monitoring/QA providing RMSE and bias by tail #**
