Updates and messages

Find out what has been happening with the UKCP User Interface below. For information about the wider UK Climate Projections set of products, go to the UKCP web pages. From time to time, the UKCP User Interface will be down due to updates to the infrastructure. Details of anticipated downtime will be provided below. Planned software updates are detailed here. For unanticipated issues a site wide message will be displayed.

News icon UKCP Enhancements - October 2020 (Published on 22/10/2020 09:57:49)
A set of enhancements to the available UKCP products are now available; these include an assessment of extremes within the Probabilistic Projections, a low emissions scenario update for UKCP Global (60 km), an assessment of the internal variability within the UKCP Projections, three European circulation indices and data on soil moisture and water balance. Further information can be found on the UKCP Website here: https://www.metoffice.gov.uk/research/approach/collaboration/ukcp/ukcp18-project-news/index

News icon UKCP Updates Part 1 - UKCP Local 2.2km correction (Published on 24/09/2020 10:49:38)
Users of the UKCP Local 2.2km climate model should be aware of an error within the computer code, affecting how much solid precipitation falls as snow and how much falls as small ice pellets. No other UKCP product is affected by the error and top-level UK climate change messages from UKCP are unchanged. Much of the existing 2.2km data can still be used for many applications, but users are urged not to use data containing projections of snow and winter temperatures over Scotland. The following variables are also affected, but to a lesser extent, and for these caution is needed in the use of the existing data: winter precipitation; UK hourly precipitation extremes; and wind extremes over the ocean and north-west coastal regions. Summer temperature, including extremes and summer mean precipitation remain unaffected. The UKCP team are planning to issue revised data in Spring 2021. A report for technical users providing more detail on this issue and guidance to help users understand how to best continue in their use of the model results is available, along with an FAQ document. These can be found on the Guidance and Science Reports page on the Met Office website here: https://www.metoffice.gov.uk/research/approach/collaboration/ukcp/guidance-science-reports

News icon UKCP Updates Part 2 - Probabilistic Projections (Published on 24/09/2020 10:48:16)
Probabilistic Projections investigation In response to feedback from a user, the UKCP team have checked projections of daily minimum and maximum surface air temperature (Tmin and Tmax) from the probabilistic projections’ component of the land scenarios (UKCP_Probabilistic). In climate model output, changes in daily mean temperature (Tmean) are usually within 0.5 degrees of the average of changes in Tmax and Tmin. However, in the UKCP_Probabilistic data larger differences were found in some of the 3000 realisations, leading to inconsistencies between the Tmax, Tmin and Tmean results. We will report back on a time-scale of approximately one month, with updated data and guidance. Any users of the current Tmax and Tmin results from UKCP Probabilistic who need a faster response are advised to contact the UKCP team for further advice. Other variables in UKCP Probabilistic, including daily-average temperature, are not affected by this issue.

News icon UKCP Updates Part 3 - UKCP enhanced capability (Published on 24/09/2020 10:47:05)
During October 2020, a suite of new tools delivering advanced functionality will become available. The new features include: • Probabilistic estimates for a range of extreme metrics at return periods of 20, 50 and 100 years for quantities such as daily maximum temperature, and daily precipitation. • Storm and weather-related metrics – including NAO indices, storm track position and intensity, and weather types. • Guidance on water budgets and guidance on global model drifts. 

News icon User interface upgrade (Published on 21/07/2020 08:40:47)
The UKCP18 User Interface has had a major upgrade. This includes the updating of a number of the underlying software packages: Iris, the analysis software; Matplotlib, the mapping and plotting software; NumPy numerical package; migration from the Pylons web frame work to the Pyramids web framework; upgrade from Python 2 to Python 3. In general users should not see any major differences. In testing it has been seen that NumPy is rounding some of the floats.

News icon Update of UKCP Regional (12km) (Published on 03/10/2019 08:03:54)

We have updated some of the gridded products from the UKCP Regional (12km) data today and can now be accessed through the UKCP User Interface.

The update includes:

  • The 12km dataset over the UK in the Ordnance Survey's British National Coordinates for a small number of coastal grid cells for Northern Ireland and Ireland.
  • The 12km dataset over the UK and Europe for maximum and minimum temperature as well as mean sea level.

You should not have been affected if you:

  • use the regional averages (i.e. country level, river basin level and administrative level).
  • access anomalies data through the User Interface

This will mainly affect those who have accessed the data through the CEDA data archive and who have analysed the whole of the UK or Europe.

Note:

  • The update does not change any of the headline findings or existing material.
  • The changes are due to a small number of grid cells being mistakenly identified as a sea cell rather than land cell. Also, incorrect units for maximum and minimum temperature and mean sea level pressure.


News icon Release of UKCP Local (2.2km) (Published on 16/09/2019 11:55:06)
On 16 September 2019, Defra, BEIS, Met Office and the Environment Agency mark the release of the UKCP Local (2.2km) climate projections. The new climate projections complement the UKCP suite of products launched last year. You can find further details about the new set of data on the UKCP website (https://ukclimateprojections.metoffice.gov.uk) and download the data from the UKCP user interface and CEDA Data Archive.

News icon Launch of the updated UK Climate Projections User Interface (Published on 27/11/2018)

On 26 November 2018, the UK Climate Projections User Interface went live. Browse this website or head to the UKCP website to find out more about the UKCP18 project.

The UK Climate Projections User Interface (UKCP UI) will be further developed as we add functionality, datasets and improve the usability of the interface based on user feedback. Visit this page regularly for information on the plans for improving the UI. Current plans in the short term are to:

  • Include regional averages for probabilistic projections
  • Include plume plots for projections over land
  • Allow direct download of the data through the user interface (rather than just maps and graphs products)
  • Include files used as input into the climate models, i.e. land elevation, land area mask
  • Include derived projections on Ordnance Survey's National Grid (currently only available through CEDA Data Catalogue)

The updated observations dataset for use alongside the UKCP18 climate model projections will be available on Wednesday 5 December 2018. In the meantime, you can find further information via:
