Total electron content (TEC) variability at Los Alamos, New Mexico: A comparative study: FORTE‐derived TEC analysis

Data collected from Fast On‐Orbit Recording of Transient Events (FORTE) satellite–received Los Alamos Portable Pulser (LAPP) signals during 1997–2002 are used to derive the total electron content (TEC) at Los Alamos, New Mexico. The LAPP‐derived TECs at Los Alamos are analyzed for diurnal, seasonal, interannual, and 27‐day solar cycle variations. Several aspects in deriving TEC are analyzed, including slant to vertical TEC conversion, quartic effects on transionosperic signals, and geomagnetic storm effects on the TEC variance superimposed on the averaged TEC values.
