## NATIVE Overview/Outline

**A mobile research facility designed for:**
**Aura validation**
**Ground-based complement to NASA field campaigns**
**Mobile INTEX Ozonesonde Network Study (IONS) station**
**Air quality monitoring**
**Investigations of pollution transport and deposition**

-  NATIVE provides a comprehensive dataset for Aura validation
-  During INTEX-B Phase 2, comparison of total ozone column
-    determined by Aura and NATIVE
-  Discussion on the discrepancy of total ozone column

## Procedures

**UV Shadowband Radiometer**
- Calculations made from Langley analyses and climatological
- ozone values determine total optical depth and total
- ozone column
**Ozonesondes**
- Total ozone amounts from integrated ozonesonde profiles and SBUV measurements above maximum balloon altitude
- Same procedure used for SHADOZ and IONS-06
- _[http://croc.gsfc.nasa.gov/shadoz/](http://croc.gsfc.nasa.gov/shadoz/)_
- _[http://croc.gsfc.nasa.gov/intexb/ions06.html](http://croc.gsfc.nasa.gov/intexb/ions06.html)_
**Microtops II**
- Measures total ozone columns

## Total Ozone Column Comparison

- - Low balloon burst on 4/27 & 5/1

## Ozone Profiles

- Strat/trop exchange observed on days with high potential vorticity (PV)

## OMI Total Ozone/ PV Plots

- During both periods of comparatively low total ozone column by satellite, areas of high PV are in place over eastern Washington

## Conclusions & Future Work

- Comprehensive data set from NATIVE for 25 days while in Richland, WA during INTEX-B Phase 2 (4/21/06- 5/15/06)
- Daily data can be found on AVDC website
- Daily plots (Press, Temp, RH, WS, WD, O3, SO2, NO/NOy, CO) can be found at our website:
- 		_[http://www.meteo.psu.edu/~btaubman/Webpage/native.html](http://www.meteo.psu.edu/~btaubman/Webpage/native.html)_
- Overall, good comparison of total ozone columns between Aura & NATIVE instruments
- Discrepancy in total ozone amounts during periods of statospheric intrusion
- Further comparison of tropospheric ozone
