## WB-57F Pre-AVE Flight Tracks

**Flights**
**Jan. 16**
**Jan. 19**
**Jan. 21**
**Jan. 24**
**Jan. 27**
**Jan. 29**
**Jan. 30**
**Feb. 02**

**• ****Demonstration of **
**WB-57 **
** ****latitude and altitude coverage**
** ****payload capacity**** **
**vertical profiling in UT/LS up to 18 km**
**- sampling over ocean, land, clouds**

**Notes:**
January 16 - test flight
January 29 flight designed to parallel Aqua track - perpendicular to subtropical jet
Jan. 19 - paralel jet axis.  Look for tracer variability along jet.
3 tropical flights
January 27 - flight to 3 ̊S - coincident with Aqua at southern end
January 29 - overflight of Galapagos - see background picture - coincident with H2O sonde launch - parallel equator to measure equatorial variability
January 30 - 2nd overflight of Galapagos - spiral descent - 2nd coincident H2O sonde launch

## Pre-AVE January 30, 2004 Flight Profile

**Takeoff 10Z**
**Climb to max**

**46 kft**

**58 kft**

**Spiral descent to 39 kft over Galapagos: sonde inter-comparison**

**2 vertical profiles at mid-point of flight**

**Level legs at 46 and 58 kft provide latitudinal gradient information**

**WB-57F profiling in the tropical tropopause layer provide an unprecedented data set for understanding this poorly sampled region.**

## Pre-AVE results

**Coordinated visit of Aura science team members**
**3 Science flights by large science team in Costa Rica**
**Total water measurement of unprecedented precision from  ALIAS instrument**
**3 flights of new TDL balloon sonde, 2 coincident with WB-57F and 1 coincidence with AIRS**
**Frost point hygrometer on WB-57F made first science quality observations**
**Tropical cirrus observed (probably formed in-situ)**
**Condensed HNO****3**** observed on ice crystals (see Gao Science paper)**
**Super-saturations of 135% were again detected in upper trop.**
**Small variability in CO****2**** profile in tropics to 11.5 km**
**Excellent cross-jet flight on January 21**

## Aura Satellite validation
TES validation
S-HIS comparison in clear sky, open water and over radiation ground sites
OMI validation
Ozone column validation
MLS validation
Spiral and vertical profiles between 20 and 60 kft.

Integrate new instruments/capabilities onto WB-57 to support Aura validation flights

Observations of atmospheric conditions in the Gulf region to US midwest

## 11/3/2004 Flight TrackTropopause Fold

**J**

- Secondary circulation around jet core pulls stratospheric air downward, folding high pv air below the jet

## Slide 14

## AVE October summary

- 8 Flights (+ 2 test flights) in 21 days that were directly coincident with Aura (~2 flights/day)
- Every flights had profiles that were coincident with Aura MLS and/or TES observation points
- Clear sky observations over water with remote sensing instruments for OMI and TES, and cross track observations for OMI over multiple cloud decks.
- A number of geophysical phenomena sampled (e.g., trop fold, biomass burning, multiple cloud layers) that will aid in Aura validation
