Abstract

The Met Office Unified Model (MetUM) is a state of the art general circulation model that has many different scientific settings. Ensuring that the code is well tested is essential, as it is used operationally worldwide, e.g. for weather & air-quality forecasts.

With over 900,000 lines of code and over 200 active developers on four continents, a comprehensive test harness is in place at the Met Office and partner sites to aid in development. However, what is available for UK academics and their groups, who wish to contribute to MetUM development, but do not have access to these resources?

This talk will discuss the recent developments made by the Met Office in running the MetUM in a virtual machine environment. I will cover using this environment for testing and training, and will give examples of the problems encountered, along with some solutions.
