Nitrogen bearing compounds play an important role in catalytic loss of stratospheric ozone and will become even more important in future. Here balloon-borne limb measurements of the time and altitude dependent variation of O3, NO2, BrO and HONO are presented, providing new insight into the NOx and NOy photochemistry of the tropical upper troposphere, lower and middle stratosphere. A new method is discussed aiming at the retrieval of the diurnal variation of UV/vis absorbing radicals. The method employs spectroscopic measurements in combination with radiative transfer modeling and a...
