Every day a maximum, minimum and 10 cm temperature, wind, wind direction and many other meteorological data are measured by the weather station and stored in the computer. In the early years we used thermometers to measure the minimum and maximum temperature at 0.1 º C, accurate after November 2005, they were taken out of service. The air pressure is measured with a barograph, which writes a line on a table that is attached to a cylinder once again and makes a complete revolution once a week. The precipitation is measured with an official rain gauge type Hellmann, which can collect a large amount of 70mm per day. On August 21, 2005 the Davis Vantage pro2 weather station was taken into use, every 10 minutes data is sent to a computer and statistics are made of, among other things, temperature, humidity, atmospheric pressure, UV radiation, sun power, wind chill, heat index, rain, wind direction and wind speed. Most equipment is installed in the garden. The data that the station collects is sent all over the world, so that other organizations such as KNMI, Meteogroup, NOAA, Metoffice, VWK, Awekas, Weatherunderground and APRS WXNET can use this data. KNMI has already made grateful use of this data for a study into urban climate, UHI urban heat island effect.

School class visiting
Every year, school classes visit the weather station in Tuitjenhorn. In addition to a nice glass of lemonade and a biscuit, the children expertly get an explanation from the weatherman of what is in the garden and what it is for. Of course there is plenty of opportunity to ask questions about the weather.
The most asked question is always: where does the thunderstorm come from?"
In 2001 a statue was placed in Tuitjenhorn of Prof. Gerard Kuiper, the well-known astronomer who was born here and later made many discoveries in America together with the astronomer Jan Oort about planets and stars. For example, the Kuiper Belt, a belt of many billions of comet-like objects consisting of stone and ice, has been named after him.
