[PEM16-04] Observation of mid-latitude sporadic E over North America by GNSS-TEC
Keywords:Sporadic E, GNSS-TEC
First, we chose the dates whose critucal frequencies of Es (foEs) were more than 12 MHz at Disisonde in Pt. Arguello (lat: 34.8, lon: 239.5) in the morning and noon in 2006 through 2015 from May to August. Second, we made GNSS-TEC maps.
We succeeded in capturing Es over America and indicated that a strong Es appeared also at different longitude can be captured by GNSS-TEC. Es observed this time had E-W direction slope. It is though that this reflects E-W wind shear.
