The 2007 World Metrology Day focused on the topic of the significance of measurements in monitoring and providing reliable data for models of climate change. Metrologists face the challenge of ensuring that these measurements confirm to the International System Units (SI) and are consistent with measurements around the world. It has been found that many of the measurements necessary to monitor climate change and other environmental issues are difficult. One of the significant elements of environmental measurement is that it requires joint effort of metrologists and scientists. The World Metrology Day and WMO are jointly working to address the issues related to improving the accuracy and effectiveness of environmental measurements. They are also making efforts to confirm these measurement to the SI, enabling metrologists assess climate change on the basis of accurate and homogeneous observational data.
