From: An Idealized Method of Simulating Residual Ionospheric Errors in Radio Occultation

Profiles of the original RIEs, the new RIEs, and the reference RIEs at different latitudes during the day (first row) and at night (second row). Solid lines, dashed lines and dotted lines represent the original RIEs, the new RIEs and the reference RIEs, respectively. These plots were created using MATLAB R2010b (http://www.mathworks.com/).
