摘 要：正This paper reports on new findings of pronounced longitudinal variations in mid‐latitude electron density over the continental US, manifested as a large-scale east-west coast difference in TEC as well as east-west difference in electron density from incoherent scatter radar （ISR） extra-wide coverage over Millstone *** implication of these results on other longitudes is also addressed. A common feature of these longitudinal east-west differences is a clear local-time variation where in the evening sectorelectron density
