## Tuesday 7th October

Today, the weather was fair, but the wind too low at both Bilbao or Fos-sur-mer. SAFIRE ATR42 stayed grounded, leaving the opportunity to analyse the first data gathered the previous days. Time also to plan for the rest of the week, with everyone eagerly awaiting a feedback from the Spanish authorities concerning clearance to fly over Madrid and Barcelona.

Over Madrid, ground-based EM27/SUN spectrometers continued their measurements under a fine weather.
