Fourth Calibration and Monitoring Workshop

The Fourth Calibration and Monitoring workshop took place between 8th-10th November 2023 at Met Office, Exeter, UK.

Thank you to all the speakers and anyone who attended the  workshop (both in person and remotely). We are in the process of uploading all the materials from the event.

We are looking for volunteers to host the Fifth workshop in late 2025. If you are interested, please email [email protected].

Event overview

In a changing climate the ability to monitor meteorological conditions accurately and robustly, coupled with the need to provide warnings of high impact events makes the calibration and monitoring of weather equipment an essential concern for weather service providers. The introduction of dual polarisation to weather radar networks has brought opportunities to improve data quality, but also raises the challenges of increasing the number of parameters to calibrate and monitor.  Furthermore, increasing international weather radar data exchange, through programs such as OPERA means that accurate, internationally traceable standards for calibration are essential if products are to be consistent across national borders. 

This workshop continues a series previously hosted by DWD* (2017, 2019) and Météo-France (2021) and aims to: share experiences of current approaches to radar calibration and monitoring, examine issues facing radar networks and approaches to mitigating them, discuss upcoming technologies and techniques that can be used to help national meteorological services, and promote international best practice.             

We would like to invite practitioners from the NMSs, academia, and industry to attend the workshop which will be held in a hybrid format at the Met Office headquarters in Exeter and online. The Met Office headquarters are located in Exeter in the southwest of England, approximately 300 km from London. There are rail links to London and airports at Bristol and Exeter. The Met Office has an ambition to achieve net zero CO2 emissions by 2030. Therefore, we encourage attendees to consider low emissions transport options, or attend virtually.
