The dataset Future Flows Climate was developed as part of the project ”Future Flows and Groundwater Levels” to provide a consistent set of climate change projections for the whole of Great Britain at both space and time resolutions appropriate for hydrological applications, and to enable climate change uncertainty and climate variability to be accounted for in the assessment of their possible impacts on the environment. Future Flows Climate is derived from the Hadley Centre’s ensemble projection HadRM3-PPE that is part of the basis of UKCP09 and includes projections in available precipitation (water available to hydrological processes after snow and ice storages have been accounted for) and potential evapotranspiration. It corresponds to an 11-member ensemble of transient projections from January 1950 to December 2098, each a single realisation from a different variant of HadRM3. Data are provided on a 1-km grid over the HadRM3 land areas at a daily (available precipitation) and monthly (PE) time step as netCDF files. Because systematic biases in temperature and precipitation were found between HadRM3-PPE and gridded temperature and precipitation observations for the 1962–1991 period, a monthly bias correction procedure was undertaken, based on a linear correction for temperature and a quantile-mapping correction (using the gamma distribution) for precipitation followed by a spatial downscaling. Available precipitation was derived from the bias-corrected precipitation and temperature time series using a simple elevation-dependant snow-melt model. Potential evapotranspiration time series were calculated for each month using the FAO-56 Penman-Monteith equations and bias-corrected temperature, cloud cover, relative humidity and wind speed from HadRM3-PPE along with latitude of the grid and the day of the year. Future Flows Climate is freely available for non-commercial use under certain licensing conditions. It is the dataset used to generate Future Flows Hydrology, an ensemble of transient projections of daily river flow and monthly groundwater time series for representative river basins and boreholes in Great Britain.

Midfielder Ashittey Ollenu Haderu has extended his contract with Accra Hearts of Oak Sporting Club Limited.The prodigy, in the company of his father, other close relations, and his agent agreed a 2-year contract extension starting from next season. Accompanied by his father Hakim Nii Amaa Ollenu, uncles Nii Amaa Ollenu Junior and Odiko Ollenu, cousin Gilbert Ashittey Ollenu, and manager Mike Annang, the precocious star penned the 2-year deal with Accra Hearts of Oak at the club’s Secretariat this afternoon.Ollenu, who joined the Club on 17th September,2011, broke into the first team in the latter part of the 2011/12 season having spent a few months in the junior team.He was handed his league debut by C.K Akonnor against Wassaman United, and it was a dream debut for the youngster who won a penalty for Osei Bonsu to convert to make the scoreline 3-0.Ollenu continued his good form by winning a penalty, converted by Bonsu in the first six minutes of the game, and scoring his first goal for Accra Hearts of Oak in a 4-1 win over Elmina Sharks in the FA Cup in only his second appearance, and first full start.The youngster got his first league goal in a 4-0 win over Berekum Arsenals on the final day of the 2011/12 season.However, the gifted dribbler scored only twice and provided seven assists in the 2012/13 season in all competitions, netting back-to-back against Liberty Professionals and Amidaus Professionals in the match-day 8 and 9 respectively.The 19-year old is yet to score in the new season, but he was brought down in the penalty box for Robin Gnagne to score Hearts of Oak’s second in the 2-0 win over Liberty Professionals. Hearts of Oak is happy to renew its contract with Ashittey Ollenu, and are looking to the youngster’s continued progression and development over the coming years.
