First wideband spectral measurement of the Earth's upwelling emission, Teresina, Brazil, 30 June 200

In 2004 REFIR-PAD was integrated as "piggy-back" opportunity on board the Laboratoire de Physique Moleculaire pour l'Atmosphere et l'Astrophysique (LPMAA-CNRS, France) gondola hosting the Infrared Atmospheric Sounding Interferometer (IASI) - balloon.

The instrument was flown for the first time on the 30th of June, 2005 from the Timon airfield, near Teresina, located in the North-East Brazil (in the region of Maranhao).

The LPMAA gondola, that hosted REFIR-PAD, was launched at 3:36 local time and landed 10 hours later at 270 km south-west of Timon. The flight reached the mean floating altitude of 34 km for about 8 h.
