Objective
The scientific objectives of CHELOSBA to investigate are:
- the seasonal and diurnal cycle of the NOy partitioning at various height in the mid-latitudes. In this respect, two major questions remain to answer: (a) How well is the NOy budget described by considering the species NO, NO2, NO3, N2O5, HNO2, HNO3, HO2NO2, ClONO2 and BrONO2? (b) Is the heterogeneous conversion of HO2NO2 into HNO2 at night and the subsequent photolysis of HNO2 in the early morning hours an important stratospheric OH-source?
- the seasonal cycle of the Cly partitioning at various heights and latitudes in particular the annual cycle of the stratospheric HCl/ClONO2 ratio
- the CH4 oxidation by measurement of the CH4/CH2O ratio. Derivation of the stratospheric OH concentration.
- the potential impacts of iodine-containing species on the stratospheric ozone
The work programme proposed comprises totally eleven balloon flights with two different kinds of payloads,
intended to become flown at Leon/Spain, Gap/France and Kiruna/Sweden during spring, summer and late
winter, respectively. Two different balloon payloads will be used for the measurements:
1. The LPMA gondola, which will accommodate the LPMA absorption FTIR together with the IUP UVvisible spectrometer.
2. The MIPAS gondola, which will accommodate the MIPAS emission FTIR.
The photochemical information obtained will be interpreted with 3-D model calculation (SLIMCAT and
TOMCAT) of the University of Cambridge. The meteorological support for the flight planning and the post flight data interpretation will be given by NILU and the Free University of Berlin meteorological groups.
The data obtained within the project will be delivered to the ZARDOZ computer, and access will be given to
any colleagues who have signed the data protocol.
