Preliminary conclusions (27 April 2005)• Zenith measurements successful
(improved deep-space calibration)• Telemetry: up- and downlink: successful, but improvement needed for SCOUT • Various other changes (heaters etc.) worked excellent (tropics !!)• Despite various ‘logistical’ problems (extremely short preparation phase in
Aracatuba) and inherent problems with clouds we have obtained good measurements at the time of the Envisat overpass.

HALO: GLORIA-AB and POLSTRACC
Demonstrator : our contribution in-line with schedule
Preparation for the SCOUT-O3 campaign (Nov/Dec 2005)
Telemetry: up- and downlink : completed and testedTC5 (for CHRISTA-NF and MARSCHALLS)
2 successful test flights for MIPAS-STR
Data retrieval of the Aracatuba campaign
17.02.2005 flight : profiles for CH1, work on CH2 in progress15.02.2005 flight : level-1 processing in progress

ENVISAT Launch : 1 March 2002
Chemistry Payload on ENVISAT: MIPAS, SCIAMACHY and GOMOS
Validation of the ENVISAT measurements :
ESABC (ENVISAT Stratospheric Aircraft and Balloon Campaign)
Earlier validation activities : middle- and high latitudes
February 2005 : Validation in the tropics
Aircraft: Bandeirante, Falcon and the Geophysica
Page 21 TROCCINOX Science Meeting, Aracatuba, 17 February 2005
Motivation for validation in the tropics
Interesting region for science, thus accurate satellite data needed
Measurements from Satellite difficult because Low temperatures at the tropopause
Relatively high vertical resolution required
Page 22 TROCCINOX Science Meeting, Aracatuba, 17 February 2005
Why aircraft measurements for Envisat validation
Envisat is in a polar sun synchronous orbit
Equator crossing time : 10 and 22 hrs local time
Distance between two orbits about 3000 km
Aircraft can carry a large payload for - internal validation- measurement of complementary species

Conclusions A – B : 28 limb scans (profiles); channel 1+2;
1st half with clouds below 13 km; 2nd half only clouds at the lower (8 and 9 km) tangent heights.
B – C: a few limb scans after the dive; channel 2 only; Thin clouds at the lower tangent heights (8 and 9 km);
C – A : 10 + 1 limb scans (in between non-linearity measurements) ; channel 2 only Thin clouds at the lower tangent heights (8 and 9 km)
Overpass 12:48 UTC at C “cloud free”

Conclusions
During the complete flight clouds were in the field of view of the MIPAS-STR instrument and of course also in that of MIPAS-Envisat, except in the last section
The last section was cloud free even at the 8 km tangent point and will be extremely useful for MIPAS-Envisat validation

Conclusions
Excellent coincidences between satellite and the aircraft measurements have been obtained for 4 flights
High quality in-situ and remote sensing data have been obtained
The measurements made during the campaign will provide the most extensive data set for the validationof Envisat in the tropics.
