This page shows the current air parameters. The T7511 temperature, relative humidity and pressure sensor from COMET SYSTEM, s.r.o. is used to perform measurements. For additional information on the sensor location, its accuracy and measurement conditions, refer to the separate page.

Current data and short-term forecast of their development are also graphically displayed on the scales in the pictures. In this case the pressure value is recalculated to sea level while the pressure values in other tables and graphs are indicated in relation to the measurement site.

The above-mentioned measuring gauge measures these values automatically. Consequently, additional values of air quality are continuously calculated and the results are recorded in the database. The course of each air physical quality can be displayed using the adjustable graphs and tables on the Archive page while the sorted extreme values of air states can be found in the table featuring an adjustable data selection interface.

Graph of hourly temperature and relative humidity averages for the last 24 hours

The green bar graph shows the average hourly air temperature values while the blue bar graph shows the relative humidity values. The graph shows the values in sequence from 24 hours ago up to the present time (last completed hour).

Current Hourly Averages of Certain Monitored Values

The first table includes hourly averages of directly measured values. The values are read every 5 minutes and consequently the hourly average of the measured values is calculated every hour.
