Variations of temperature profile of the atmosphere at the locations of Yakutsk EAS array and TAIGA observatory are investigated. Using data from hyperspectrometer AIRS onboard the Aqua satellite, a base of daily temperature profiles has been created for the period September, 2016 – December, 2017. Analysis of variations of the average temperature in the layer ~ 300 hPa above the observation level for the period from November 1st, 2016 to March 31st, 2017 is presented.
We discuss a problem of cloud cover monitoring in the areas of Yakutsk EAS array and TAIGA observatory at nighttime during annual observations from October to April. It is shown, that utilization of data from instruments aboard Terra, Aqua, SNPP and NOAA-20 satellites, received by ground stations of Altai State University and processed up to level 2 (retrieval of geophysical parameters of atmosphere), provides an opportunity to carry out monitoring observations of cloud cover structure at night-time with high spatial resolution and frequency which is sufficient to make cloud correction of detector arrays readings.
