## Description
- we start our flight with a small circle to climb up to FL410 (*c_climb*)and ramp up all instruments east of Barbados.
- we continue with a circle of 72km radius *c_meteor* in coordination with Meteor measurements (within the SEA-POL scan range) and with dropping 12 sondes. Meteor plans to sit at the western most point of the circle and we might overpass it twice.
- we continue circling our way east *c_mid*, *c_ec*, *c_south* and with 12 sondes per circle.
- we will next go on the EarthCARE track entering it at *ec_south*,  meet EC at 17:22:37 UTC at *ec_under*, and continue to *ec_north*. A procedure turn will bring us back to on the EC track to the waypoint *wp_home*
- we head home and do one last circle *c_west* on the way, again with 12 sondes.

In total we plan to throw 5*12=60 sondes.
