Abstract
In order to analyze muon flux variations caused by extra-atmospheric processes, it is necessary to introduce corrections for meteorological effects. To take the temperature effect into account, we must know the temperature profile of the atmosphere. Vertical temperature profiles obtained from NOAA satellites and calculated using the model of the Global Data Assimilation System (GDAS) are compared to data from the Central Aerological Observatory (CAO, Dolgoprudny) for standard isobaric levels. The average temperature difference for most levels does not exceed 1 K. A comparison of the data from the URAGAN hodoscope, corrected for the temperature effect using data from the CAO, NOAA, and GDAS, shows excellent mutual agreement. A series of integral time counting rate and the anisotropy of the muon flux for 2007–2014, corrected for atmospheric effects, are presented.
