Belgium – Measuring instruments – Supply of ozone probes, radio probes and interfaces

RMI has maintained a continuous time series of ozonesonde measurements since 1969, which is of invaluable importance for climate research and the monitoring of the ozone layer under the UN Montreal Protocol. In addition, these soundings provide essential parameters (such as the effective temperature for ozone absorption) required to calculate and forecast the UV index for the public. RMI also acts as the official Quality Assurance/Science Activity Centre (QA/SAC) for ozonesondes within the World Meteorological Organization (WMO). The upcoming contract for the supply of measurement equipment (approx. 150 soundings per year) is divided into two lots: - Lot 1 - Ozonesondes: Procurement of specific ozonesondes. - Lot 2 - Radiosondes and interfaces: Procurement of the corresponding radiosondes and the necessary data-transfer interfaces.
