    During CLARE’98 several radiometers were operated. In this paper an overview of the instruments operated by KNMI, TUE and TUD/IRCTR is given. This includes the net- and shortwave radiometers operated by KNMI and the sky temperature observations as measured by two IR-radiometers. One IR-radiometer was pointing vertically upwards, the second instrument was mounted in the 25m antenna dish of the Chilbolton radar. A 20/30/50 GHz microwave radiometer (20/30 GHz is on loan from ESTEC) was used to derive the column integrated liquid water and water vapour. Satellite data from the AVHRR instrument were collected and analysed. A time-lapse S-VHS video system was used to monitor the clouds at day-time. All systems were continuously operational during the CLARE’98 campaign, except for the upward pointing IR-radiometer, no technical problems were encountered. Data has been collected, calibrated and submitted to the CLARE’98 database.
