From Roberto Colombo (University of Milan, Italy), 12 September We’ve just been working out in the Czech Republic to help with the development of a concept for a candidate Earth Explorer mission called FLEX. The HyFLEX field campaign tests the mission’s measurement concept – and some of these measurements have to be taken from a cherry picker over the forest canopy. The cherry picker ‘T148 MP 27’ is a hydraulic work platform truck that was manufactured by Tatra at the beginning of 1970 in Kopøivnice, in what was Ceskoslovenska Republika. It was originally red and white, with three yellow arms. Now scattered with spots of rust, this machine has had a long...

HyFLEX: above the forest

From Dirk Schuettemeyer (ESA) & Uwe Rascher (Forschungszentrum Jülich), Germany, 5 September A closer look at the datasets we had gathered in Germany confirmed that these first measurements were fine so we decided to carry on with the next phase of the campaign and move on to the Czech Republic. So, as of 30 August we have been in the Beskids mountains just on the border between the Czech Republic and Slovakia. We first had to set up all instruments in the forest to measure the more complicated fluorescence signal that comes from the trees’ pine needles in this hilly terrain.  The main challenge for the airborne measurements is that the instrument...
