RELEASE NOTES FOR CRU CY v4.03: 15 May 2019 NOTE: Please read the main document, 'Read_Me_CRU_CY.txt', as well. The 4.03 release of the CRU CY dataset covers the period 1901-2018. The best published reference to use is that of the underlying dataset, CRU TS: Harris, I., Jones, P.D., Osborn, T.J. and Lister, D.H. (2014), Updated high-resolution grids of monthly climatic observations – the CRU TS3.10 Dataset. Int. J. Climatol., 34: 623–642. doi: 10.1002/joc.3711 This release uses the updated country definitions introduced in v4.01 (and v3.25); that parallel release using old definitions is still available to allow checking. Please see the separate file, 'Read_Me_CRU_CY_4.03_Updated_Country_Definitions.txt', for details. As always, please contact BADC in the first instance if you have any questions, observations or suggestions. If, however, you wish to contact CRU directly about these datasets, please contact me at i.harris@uea.ac.uk, as mail to other members of the Unit will be passed through to me anyway.
