Simultaneous sampling for microorganisms was accomplished at altitudes of 690, 1,600, and 3,127 meters. The location of temperature inversions in relation to collection altitude determined, to a great extent, the micro-population. High micro-populations were found when an inversion was above the sampling altitude, and low populations when the inversion was below the sampling altitude. Diurnal periodicity which could be generally correlated with periods of minimum and maximum convective activity was observed. Evidence is presented showing that the micro-population is more stable at higher altitudes than at lower altitudes.
