Long Term Average Observation of First Two Harmonics of Cosmic Ray Daily Variation
Cosmic ray daily variation is directly related with changes in interplanetary conditions. The significant and systematic deviations in the amplitude and phase of the diurnal, semi-diurnal variation of cosmic rays from the average values is due to strong geomagnetic and solar activity. The amplitudes and phases (time of maxima) of first two harmonics of cosmic ray daily variation show 11/22 year...
متن کاملStudy of the Diurnal Variation of Cosmic Rays during Different Phases of Solar Activity
The pressure-corrected hourly counting rate data of neutron monitor stations, situated in different latitudes, have been employed to study the variation of cosmic ray diurnal anisotropy for a long period of 44 years (1965-2008). Some of these neutron monitors are situated in low latitudes with high cutoff rigidity. Annual averages of the diurnal amplitudes and phases have been obtained for each...
متن کاملDiurnal variation in the nitrate content of parsley foliage
The diurnal fluctuation of nitrate concentration in the foliage of three parsley subspecies (plain-leafed, curly-leafed and turnip rooted parsley) cultivated in the spring and autumn of two consecutive years was examined. Nitrogen was applied at 30 (Control), 75, 150, 300 mg kg-1 in both years, but with the addition of 450 mg kg-1 in year 2. Harvest was carried out at 08:30, 12:30 and 17:30 on ...
متن کاملCosmic Ray Sidereal Diurnal Variation of Galactic Origin Observed by Neutron Monitors
Cosmic ray sidereal diurnal variations observed by neutron monitors are analyzed for the period 1961-1978, by adding 1D4 station-years data to the previous paper (Nagashima et al., 1983). Also the dependence of the sidereal variations on Sun's polar magnetic field polarity is examined for two periods; the period of negative polarity in the northern region, 1961-1969 and the period of positive p...
