(a) The vertical downward component of the input SV (black curve) and non-advective SV (gray curve) from GRIMM (2002.0–2005.0) at 34°N, 77°E and 17°S, 107°E, both at 400 km altitude. (b) The eastward component of the input SV (black curve) and non-advective SV (gray curve) from CM4 (1960.0–2002.0) at NGK (52°N, 13°E, 0 km) and HER (34°S, 19°E, 0 km).
