(9)Here, the diagonal matrix W d holds weights given by the reciprocals of the input data variances, where (sigma_{text{sat}}^{2} = left( {5.26^{2},4.31^{2},3.37^{2} } right);{text{nT}}^{2}) for the respective radial, latitude, and longitude satellite vector component data, and (sigma_{text{ns}}^{2} = 96.1^{2},{text{nT}}^{2}) for the near-surface data.
The unit current vector for longitude segmentk(1 … 360) of current j(1 … N C ) is then given by (10 1112 wherewhere α jk is the angle between geographic north and the linear current segment k of current j.
To compute the longitude and latitude angles, a normalized vector η i W in the direction of the ray vector is constructed by using the perspective project method: η i W = R C W ( ϕ ^ W ) I i x - u 0 f u I i y - v 0 f v 1 T (14).
Through rank-1 decomposition, large-scale ionospheric variations (U^{(1)}), (U^{(2)}) and (U^{(3)}) are achieved, which are the resulting unit-norm vectors for time, longitude, and latitude mode, respectively.
To obtain large-scale characteristics of the ionosphere, rank-1 decomposition is used to obtain (U^{(1)}), (U^{(2)}), and (U^{(3)}), which are the resulting vectors for the time, longitude, and latitude modes, respectively.
The spatial distribution of horizontal winds is consistent with the divergent tidal flow as shown in earlier studies (Del Genio and Rossow 1990); the sub-solar longitude at observation time was 143°; thus, winds vectors in the local afternoon are obtained.
Kovacs[31] defines a position vector containing the following data fields: MAC id, C2C NET ID, timestamp, position in latitude, longitude and altitude, and speed and heading.
A total of 350 parameters can be extracted from the CGM data fully automatically and divided into main classes: Angles consisted of longitude and latitude angles of the P, R and T-loops, in particular, the angle of the maximum vectors and at further defined positions in the loops and angles between the maximum vectors of the P, R and T-loops.
