Similar Unified Model suites with global and regional domains are used by many other national or military weather agencies around the world for operational forecasting.
[6] The Unified Model software suite is written in Fortran (originally 77 but predominantly 90 as of 2003[update]).
[9] The Met Office runs a range of Numerical Weather Prediction suites using the UM.
This high resolution model provides information on mountain waves for a variety of locations around the UK and other areas of interest to the Met Office.
Unified Model suites which are similar to those from the Met Office are run by the Australian Bureau of Meteorology, the Australian Commonwealth Scientific and Industrial Research Organisation, the South African Weather Service, the Norwegian Meteorological Institute, the New Zealand National Institute of Water and Atmospheric Research, the [South] Korea Meteorological Administration and the National Centre for Medium Range Weather Forecasting, a subordinate office of the Indian Ministry of Earth Sciences.
The Australian Bureau of Meteorology, have an operational 12 km resolution global forecasting system utilizing the Unified Model.
The (South) Korea Meteorological Administration have an operational 10 km resolution global forecasting system utilizing the Unified Model.
[16] This includes calculating the concentrations of climatically relevant gases such as methane and ozone, as well as the composition and evolution of aerosols.
JULES can also be used offline to estimate the impacts of different climate models on the land surface and hydrology.
