T.Arunamani'>Enclosure 1: Brief Account of work done by Dr.T.Arunamani
I have been actively involved in the investigations of lower ionospheric phenomena and middle atmospheric minor constituent and ion modeling for over 20 years. Salient features of some of these investigations are given below.
-
For my doctoral work, the lower ionospheric phenomena were investigated using LF amplitude measurements. Model the D – region profiles were developed ( based on existing neutral and ion chemical schemes) which would successfully explain the diurnal seasonal and transient ( flare time) behavior of the region.
-
After obtaining Ph.D ., work on the development of one dimensional middle atmospheric minor constituent modeling was initiated , as part of the Indian Middle Atmosphere Program( IMAP) at Waltair. Minor constituents of aeronomic interest Viz., odd oxygen, odd hydrogen and odd nitrogen in the mesosphere and n the stratosphere , in addition to the above Odd chlorine and some of the trace gases like CCl4, CF2Cl2,CFCl3, CH4 etc were computed. Basing on these species, the ion composition models were developed. The neutral species were found to represent the low latitude lower ionosphere fairly accurately.
-
Studies on the sensitivity of the model calculations of mesospheric minor constituents to variations in certain input parameters like Vertical eddy diffusion coefficient, temperature, water vapor and initially assumed values of the minor constituents showed that the minor constituents do not have any effect on their concentrations. On the other hand these are sensitive to changes in both temperature and water vapor
-
The effect of solar activity on the minor constituents in the mesosphere and lower thermosphere
-
The one dimensional models developed were profitably used in a study of the effects of artificial heating in the D- region ion composition.
-
A study of the seasonal variation of LF propagation data in conjunction with variations in Ozone concentrations, used in the calculation of model D – region profiles brought out very clearly the significance of ozone in the mesospheric processes.
-
The investigation on the diurnal asymmetry in the D – region electron density also showed that mesospheric ozone variability has greater role to play.
-
A Two – dimensional middle atmospheric model was developed which involves the use of realistic chemistry schemes and two dimensional transport processes.. The transport schemes involves meridional and vertical wind velocities. The wind velocities were calculated using the diabatic heating rates. Important input parameters for the calculation of heating rates are Ozone and temperature.
-
Using the two dimensional SOCRATES ( Simulation of Chemistry Radiation and Transport of Environmentally important Species) Model developed at NCAR, and also the Ion chemistry of George Reid, the Transition Heights , which are defined as the height where the dominance of water cluster ions to Molecular ions is observed, are calculated and the results were published
