Abstract:
Several atmospheric / meterological parameters, including atmospheric dust load, sky condition and solar UV (? = 270 - 310nm) radiation flux have been monitored on a daily basis at the GRACE observatory site in Mt. Abu for the last several years. In the present communication we report the results of our preliminary analysis of these data, especially the diurnal and seasonal variations in various parameters and their effect on observations with the TACTIC imaging Cerenkov telescope array.
