| Popis: | The correlation between polar conductivity and the concentration of atmospheric small ions with mobilities higher than 10−4 m2 v−1 sec−1 has been investigated by means of a Gerdien conductivity meter. The apparatus has been operated in Socorro at an elevation of 4620 ft and at 10,640 ft on a nearby mountaintop at the Langmuir Laboratory. The correlation coefficient between conductivity and concentration is higher than 0.97 for positive as well as for negative ions at both locations. A least-squares analysis of the results of measurement furthermore shows that the conductivity is proportional to the concentration of small ions. The over-all average mobility has been found to be 1.6×10−4 m2 v−1 sec−1 for small positive ions and 2.0×10−4 m2 v−1 sec−1 for small negative ions. The average fair-weather negative and positive conductivities on the campus and the negative conductivity at the Langmuir Laboratory are essentially the same, having a value of 1.4×10−14(ohm-m) −1. The average positive conductivity at the mountain site is 3.2 times the other values. This is attributed to the higher atmospheric electric field, with a resultant ‘electrode’ effect. |
