The Royal Meteorological Institute of Belgium (RMI) has a network of 18 automatic weather stations (AWS) recording meteorological parameters such as pressure, temperature at different levels, relative humidity, wind speed and direction, radiation and precipitation. In this paper we present the results of the intercomparison of the different types of shelters used in the network. Besides an artificially ventilated Stevenson shelter used as reference temperature, an internally developed shelter is also used for additional height measurements at 2, 10 and 30m. In addition,the Barani Helix shield has also been compared to the RMI shelters.
