Flight and Measurement Plan
Ingredients
• Predicted trajectory (direction, time of the day)• Predicted flight duration• Envisat overpasses• Predicted clouds and convective activity• Predicted float level(s)
• Science objectives
TELIS-Meeting 4.12.2007 H. Oelhaf 3
Review of TELIS+MIPAS-B scientific objectives
• Closure of chemical families (NOy, Cly, HOx, Bry) still missing(at least above the ER2 cruising altitude), nota bene: complementarity and consistency checks
• Scientific issues associated to the tropical transition layer (TTL) are getting more and more important

Scientific Objectives of TELIS+MIPAS
TELIS-Meeting 4.12.2007 H. Oelhaf 5
What TELIS could contribute (Synergies)
• Closure of chemical families and understanding of family coupling
• NOy: NO3• ClOy: HCl, ClO, HOCl, Cl2O2• BrOy: BrO, BrONO2, HBr (?), BrCl, HOBr, …• HOx: HO, HO2
• UTLS: CO, PAN (?), acetone (?), HCHO (?), short-lived source gases
• Diurnal variation of radicals: NO, NO2, HO, HO2, BrO, ClO, …
• Non-LTE issues and intrusion of mesospheric air: NO, CO, ..
• Consistency checks: HNO3, H2O, ClO, others (?)
• Spectroscopy issues: spectroscopic parameters of species measured by both instruments in different bands
TELIS-Meeting 4.12.2007 H. Oelhaf 6
What TELIS could contribute (Synergies (cont.))
• UTLS region (what can TELIS provide in terms of altitude coverage and accuracy??)
• Qualification of TELIS and satellite validation (direct & indirect)
• Utilisation of synergy of ENVISAT (and other satellite) observations and coordinated field measurements
• TTL: Water isotopes as complement or for cross-check (CH3D ?)
What else will/would be a nice complement:
UV-Vis Mini-DOAS (K. Pfeilsticker, Uni. HD)
An instrument to measure the actinic flux in the UV and visible spectral region (simpe instrument by Frank Hase flew as piggy back).
