The CRU CY version 3.23 dataset consists of country averages at a monthly, seasonal and annual frequency, for ten climate variables, including cloud cover, diurnal temperature range, frost day frequency, precipitation, daily mean temperature, monthly average daily maximum and minimum temperature, vapour pressure and Potential Evapo-transpiration.
This dataset was produced in 2015 by the Climatic Research Unit (CRU) at the University of East Anglia.
Spatial averages are calculated using area-weighted means. CRU CY3.23 is derived directly from the CRU TS3.23 dataset. CRU CY version 3.23 spans the period 1901-2014 for 289 countries.
To understand the CRU-CY3.23 dataset, it is important to understand the construction and limitations of the underlying dataset, CRU TS3.23. It is therefore recommended that all users read the paper referenced below (Harris et al, 2014).
CRU CY data are available for download to all CEDA users.

CRU CY 3.21 data files acquired directly from CRU in 2013.
CRU CY is derived directly from the CRU TS dataset, and version numbering is matched between the two datasets. Thus, the first official version of CRU CY is v3.21, as it is based on CRU TS v3.21. An advisory note was issued by CRU in July 2013 regarding an issue in the spatial area of Northeast Africa, for the PRE and WET variables only. Details are given in the documentation as part of the archive.
The CRU CY 3.23 data are available in human readable ASCII file format. To understand how to read the CRU CY 3.23 data files, please refer to the CRU_CY_3.23_File_Formats_explained PDF documentation (under Linked Documentation below).
