June 1, 2012  The new HA­LO (High Al­ti­tude and Long Range Re­search Air­craft) re­search air­craft her­alds a new chap­ter in the his­to­ry of Ger­man at­mo­spher­ic re­search and Earth ob­ser­va­tion. HA­LO is based on a Gulf­stream G 550 ul­tra-long range busi­ness jet. The com­bi­na­tion of range, cruis­ing al­ti­tude, pay­load and com­pre­hen­sive in­stru­men­ta­tion make the air­craft a glob­al­ly unique re­search plat­form.

June 1, 2012  The HA­LO (High Al­ti­tude and LOng Range) re­search air­craft is based on the ul­tra-long-range G 550 busi­ness jet pro­duced by Gulf­stream Aerospace. With a range of more than 8000 kilo­me­tres, mea­sure­ments on the scale of con­ti­nents are pos­si­ble; the re­search air­craft can reach all re­gions, from the poles to the trop­ics, and re­mote ar­eas of the Pa­cif­ic Ocean.

October 7, 2014  The ACRIDI­CON mea­sure­ment flights last­ed about sev­en hours. Among oth­er things, the anal­y­ses in­clud­ed how clouds in clean rain­for­est air dif­fer from those found over pol­lut­ed and de­for­est­ed re­gions.
