Long Term Ionospheric VTEC Variation During Solar cycle 24 as Observed from Indian IGS GPS Station 印度IGS GPS站观测的第24太阳周期电离层VTEC的长期变化

— We use the IGS (International Geodesic Survey) dual-frequency GPS data of Indian low latitude IGS Station IISC, Bangalore (13.02 ᴼN, 77.57 ᴼE), to compute the Total Electron Content (TEC) to study the solar activity variation of the ionosphere. To study the TEC variation with solar activity, we choose a complete solar cycle 24 during the period 2007-2020. We study the variation of TEC with sunspot numbers which is the quantitative measure of the solar activity. We observe the variation of TEC with the solar activity parameter such as solar flux and the EUV flux. The estimated TEC gradually increases from a minimum to maximum during 2007 to 2014 and then again decreases during 2015-2020 to a minimum which follows the sunspot numbers variation over the complete solar cycle. We use the EOF decomposition model using GPS-TEC data for the entire solar cycle. The diurnal, seasonal, annual TEC variation and its corresponding trend with solar activity are observed using the EOF-TEC method. The EOF-TEC data is highly correlated to GPS-TEC data with a value of correlation coefficient of 0.9323. The performance of the model is also good with the RMSE value of 5.7891 and the NRMSE value is 16%. We also use the IRI-2016 TEC to study the diurnal, annual variation of TEC with solar activity and verify our observed and model data. The IRI-TEC is comparatively low but the solar activity dependence of TEC matches with the GPS-TEC and EOF-TEC values satisfactorily. the diurnal TEC attains a maximum value at the afternoon 13:00-17:00 IST for this low latitude station which is observed for all TEC throughout the solar cycle. We observe that for seasonal variation, the value of GPS-TEC is maximum for the equinox. The equinoctial GPS-TEC is maximum followed by winter and summer. A similar kind of outcome is found in EOF-TEC. We show the positive correlation between TEC, sunspot, solar flux (F10.7 cm), and EUV flux for the entire solar cycle.
利用印度低纬度IGS站IISC, Bangalore(13.02ᴼN, 77.57ᴼE)的IGS (International Geodesic Survey)双频GPS数据,计算电离层总电子含量(TEC),研究太阳活动的变化。为了研究TEC随太阳活动的变化,我们选择了一个完整的太阳周期24(2007-2020)。我们研究了TEC随太阳黑子数的变化,黑子数是太阳活动的定量指标。我们观察了TEC随太阳通量和极紫外通量等太阳活动参数的变化。估算的TEC在2007 - 2014年期间由最小值逐渐增加到最大值,然后在2015-2020年期间再次减小到最小值,这与太阳黑子数在整个太阳周期内的变化有关。我们利用GPS-TEC数据对整个太阳周期使用EOF分解模型。利用EOF-TEC方法观测了TEC的日、季、年变化及其随太阳活动的变化趋势。EOF-TEC数据与GPS-TEC数据高度相关,相关系数为0.9323。该模型的RMSE值为5.7891,NRMSE值为16%,性能也较好。我们还利用IRI-2016 TEC研究了TEC随太阳活动的日、年变化,并验证了我们的观测数据和模型数据。ir -TEC相对较低,但其对太阳活动的依赖性与GPS-TEC和EOF-TEC值吻合较好。在整个太阳活动周期内,该低纬度站的日TEC在下午13:00-17:00达到最大值。我们观察到,从季节变化来看,GPS-TEC值在春分时最大。分点GPS-TEC最大,其次是冬季和夏季。EOF-TEC也有类似的结果。在整个太阳周期内,TEC、太阳黑子、太阳通量(F10.7 cm)和极紫外通量呈正相关。

What exactly Destiny is an exploration from a scientific viewpoint 从科学的角度来看,命运号到底是什么
Pub Date : 2021-06-30 DOI: 10.26438/ijsrpas/v9i3.710
Sumeru Ray (Maharshi MahaManas)
: 'Destiny' is a self-created automatic kinetic energy and force and also a cosmic system that came into existence as soon as the creation of the universe began with the Big Bang. This abstract being is the originator of all cosmic events and activities. At the moment of the explosion, it is automatically determined when, where and what will happen one after the other successively. That is Destiny. Destiny is nothing but the spontaneous natural creator of inevitable future events through action-reaction-interaction, causation, etc. Whatever is happening here, Destiny is at the root of everything, Destiny is responsible for everything. This Destiny is predetermined and unchangeable self-created cosmic system. However, in order for Destiny to be effective, it has to proceed on the path of logic, subject to various factors, subject to environmental conditions, causes, action-reaction interaction, etc. Some of us are happy and some are sad, some are successful and some are unsuccessful because of Destiny. Destiny is responsible for all our troubles problems and misery. Therefore, it is necessary to know the Destiny very well
“命运”是一种自我创造的自动动能和力量,也是一种宇宙系统,它从宇宙大爆炸开始创造就存在了。这个抽象的存在是所有宇宙事件和活动的起源。在爆炸发生的那一刻,系统就会自动确定依次发生的时间、地点和事件。这就是命运号。命运只不过是通过作用-反应-相互作用、因果关系等,自然自发地创造不可避免的未来事件。不管这里发生了什么,命运是一切的根源,命运要对一切负责。这个命运是预定的和不可改变的自我创造的宇宙系统。然而,命运要想有效,就必须走在逻辑的道路上,受制于各种因素,受制于环境条件、原因、作用-反应的相互作用等。我们中有些人快乐,有些人悲伤,有些人成功,有些人失败,这都是命运使然。命运要为我们所有的烦恼、问题和痛苦负责。因此,很有必要了解命运
