Comparison of Pedersen conductivities for October 10, 2002; a temporal variations of the height-integrated Pedersen conductivities derived with the EISCAT UHF radar (solid line) and the photometer observations (closed circle) between 18:00 and 23:30 UT on October 10, 2002. b Temporal variation of the ratio of the height-integrated Pedersen conductivity from the photometric value to the EISCAT radar value
