Particle Accretion Rates: Variation with Latitude.
Reported accretion rates for cosmic spherules ranging in diameter from 1 to 400 micro appear to increase with increasing latitude. The apparent variation is most closely related to geomagnetic latitude. Preliminary culations suggest that electromagnetic interactions could cause only charged particles less than about 10-(2) micro in diameter to impinge preferentially at high latitudes.
