The Košetice observatory was established in 1988 and is operated by the Czech Hydrometeorological Institute (CHMI). The primary objective is to measure and evaluate the long-term trends of pollutants at the background environment of the Czech Republic and Europe. The station is involved in several international projects and programmes focusing on air quality monitoring at the international level. Together with the partner organisations (Masaryk University, Institute of Chemical Process Fundamentals of CAS, Global Change Research Institute of CAS), it forms the ACTRIS-CZ Research Infrastructure.

The Košetice observatory is the workplace of the Air Quality Division and the Professional Meteorological Station of CHMI.

CHMI operates 39 professional meteorological stations. There are 25 stations of the same type as the Košetice station. Another type of the CHMI measuring stations includes automatic stations (approximately 150 stations) and automatic rain-gauge stations (over 150 stations).

Meteorological measurements and observations at the Košetice observatory are, according to the rules established by the World Meteorological Organization (WMO), sent every hour as a SYNOP message containing the values of meteorological elements. These data serve as a basis for weather forecasts prepared by the Regional Forecasting Office (RPP).

The Košetice observatory is a part of the Early Warning Network. This network is a component of the Radiation Monitoring Network of the system for monitoring the radiation situation of the Czech Republic. The State Office for Nuclear Safety (SÚJB) is responsible for managing the network. Measurement of the photon dose equivalent power is carried out at the observatory and its value has never exceeded the degree of damage to human health. Measured values usually fluctuate within the range of 0.12 to 0.15 μS/h, which corresponds to the natural background of the CR (0.14 μSv/h = 1226 μSv/year). For example, an increased likelihood of cancer corresponds to a dose of 100 mSv/year.
