Sporadic sodium and E layers observed during the summer 2002 MaCWAVE/MIDAS rocket campaign
On 5July 2002, a MaCWAVE ( M ountain and C onvective W aves A scending VE rtically) payload launched from Andøya Rocket Range, Norway, observed narrow enhanced layers of electron density that were nearly coincident with sporadic sodium layers measured by the Weber sodium lidar at the nearby ALOMAR O...
