Abstract
Various heating and cooling mechanisms which are operative in the lower E-region are discussed and their relative importance in different altitude range is shown. These heating and cooling rates are then used to derive the electron temperature T{sub e}. The calculated values of electron temperature are found to be higher than neutral temperature through out the altitude range 100 {approx} 150 km, with the difference increasing with increase in altitude. However, compared to observed values of T{sub e}, the calculated values are still smaller below about 130 km. Above this altitude, the calculated values become larger. Estimation of T{sub e} for different, suggested values of heating efficiency due to dissociative recombination, show that T{sub e} profile obtained even be assuming a constant value of 1.3 eV is in fairly good agreement with those derived based on variable values of this parameter.
