# Satellite monitoring of atmospheric temperature profiles and cloud cover over the Yakutsk EAS array and the TAIGA observatory

## TL;DR

This study demonstrates how satellite data can be used for near-real-time atmospheric temperature and cloud cover monitoring at observatory sites, improving meteorological corrections for cosmic ray detection.

## Contribution

It introduces a method for using satellite data from Terra, Aqua, Suomi-NPP, and NOAA-20 to monitor atmospheric conditions at specific observatory locations.

## Key findings

- Satellite data enables near-real-time atmospheric monitoring.
- Ground station processing provides geophysical atmospheric parameters.
- Monitoring improves accuracy of cosmic ray detector measurements.

## Abstract

We consider the problem of night-time atmosphere monitoring at the locations of the Yakutsk EAS array and the TAIGA observatory for the annual October-April period of observations at these facilities. It is shown that the use of data from instruments aboard Terra, Aqua, Suomi-NPP and NOAA-20 satellites, received by the ground stations of the Altai State University, Russia, and processed to Level 2 (retrieval of geophysical parameters of the atmosphere), gives the possibility of the near-real-time monitoring observations of the cloud cover structure and the temperature profiles at night with a spatial resolution and a frequency sufficient for meteorological correction of the detector readings.
