Broadband Backhaul Communication for Stratospheric Platforms: The Stratospheric Optical Payload Experiment (STROPEX) [PDF]

, 2006
A high bitrate optical downlink was performed by the stratospheric optical payload experiment (STROPEX), a part of the EU CAPANINA project. The STROPEX objectives were to design and build the necessary hardware to demonstrate an optical backhaul downlink

Time dependent profile retrieval of UV/vis absorbing radicals from balloon-borne limb measurements – a case study on NO₂ and O₃ [PDF]

Atmospheric Measurement Techniques, 2010
A new "Bayesian" minimization algorithm for the retrieval of the diurnal variation of UV/vis absorbing radicals (O3, NO2, BrO, OClO and HONO) from balloon-borne limb scattered skylight observations is discussed.

The stratospheric quasi-biennial oscillation observed in the semidiurnal ground pressure data [PDF]

Annales Geophysicae, 1995
Ground pressure observations made at Macao (22°N, 113°E) from 1953 to 1991 are analyzed and compared with the stratospheric quasi-biennial oscillation (QBO) data obtained during the same interval.
