Description
This work presents the development of a mathematical relationship between ground-based magnetometer and satellite data to estimate long-term values of ionospheric vertical drift during local daytime. The expression is developed based on a relatively long-term data set during 2008-2014 and validated with radar observations. The obtained correlation coefficient values computed using observed and derived vertical drift velocities are 0.78 and 0.83 for two different sets of radar measurements during 2008-2014 when data was available. In this talk, we will show that this approach is applicable during both quiet and disturbed conditions; and forms a basis for development of high resolution vertical drift models in equatorial latitudes.
