Diurnal variations in the electrical field intensity under smoke from forest fires

The electrical field in the Earth's atmosphere is one of the permanently present factors having an influence on the state and changes in the environment. The complex interrelation between the temporal variations in this field on the one hand and the physical, chemical, and biological processes that form the environmental state on the other hand determines the interest in monitoring atmospheric electricity as both an affecting factor and an indicator of the observed environmental changes. Among the found regularities of temporal variations in the electrical field, the most well known belong to the good weather conditions. These regularities are the following: diurnal unitary variations caused by change in the Earth's charge as a whole; the electrode effect related to accumulation of voluminous positive charges near the Earth's surface; electrooptical correlation in the optical hazes expressed as the dependence of field intensity on aerosol particle concentration; and some others.
