The radiation component of GAW has concentrated its efforts on UV radiation, while specialized WMO programs have dealt with other aspects of solar radiation (for example, radiation measurements are part of the WMO Commission on Instruments and Methods of Observation (CIMO)). In this frame, in 1994, WMO established the "WMO Scientific Steering Committee on UV Monitoring", which, after March 1999, became the Scientific Advisory Group on UV radiation (SAG UV). In the last three decades, there has been substantial improvement on the accuracy of UV measurements. An important contribution of GAW in this sense has been the establishment of World and Regional Calibration Centres for UV. In addition, GAW has encouraged intercomparisons and many of them have been carried out under the auspices of WMO.
