A worldwide increase in radar mleteor echo rates in 1963 correlates with the injection of massive quantities of volcanic dust into the upper atmosphere by the explosion of Mount Agung in Bali in March 1963. The consequent change in atmospheric radiative heating most probably produced the increase by changing the air density gradient.
