EN-SCI has attended ISARRA 2018 event

A community of scientists discussed the use of unmanned aircraft for atmospheric research. EN-SCI see’s this as an excellent opportunity to modify their well known and successful ECC Ozonesonde to fit inside these small unmanned aircrafts. This would allow data of the ozone to be collected at a horizontal level rather than the traditional vertical level you get from a weather balloon. Visit to learn more about this event.
