Current Datasets and Static ClimatologiesThe CRU TS dataset was developed and has been subsequently updated, improved and maintained with support from a number of funders, principally the UK's Natural Environment Research Council (NERC) and the US Department of Energy. Long-term support is currently provided by the UK National Centre for Atmospheric Science (NCAS), a NERC collaborative centre. CRU gratefully acknowledges the support of all these funding agencies.

| Notes | The 'TYN SC' scenarios of possible future climate change are no longer recommended for use,
because they are based on older generation climate models and no support is provided.
The data are still available for the purposes of replicating previously published work that may have used these data. For scenarios based on newer generations of climate models, see ClimGen. |

Availability Some data is available from the CRU website. However, most recent data (CRU TS, CRU CY) is distributed via CEDA. DropBox may be used in extraordinary circumstances to allow timely access to new releases. Where the status is marked as 'available on request', please email cru@uea.ac.uk, stating which dataset(s) you require and the area of research you intend to use them in. Please do not request those datasets marked as 'superseded', unless you are certain that you require them. |
|||||||||||||||||||||||||||||||||||||||||||||
Conditions of use The various datasets on the CRU website are provided for all to use, provided the sources are acknowledged. Acknowledgement should preferably be by citing one or more of the papers referenced. The website can also be acknowledged if deemed necessary. |

References: Please always reference appropriately when using these datasets.

Data Formats Early datasets used a packed format which minimised storage requirements, known as 'GRIM'. This presented all the data for each gridcell in turn. The advantage was that the missing data (oceans, Antarctica) was simply not included. The disadvantage was that it required the user to reassemble the grids at the other end: a task carrying implications for storage and processing. CRU TS 2.10 was the last version to be produced in this format; it has since been converted to ASCII gridded format (below). Current gridded products (CRU TS) are presented either as ASCII grids, or in NetCDF format. The ASCII grids are 720 columns wide and 360 rows 'deep', with subsequent monthly grids concatenated onto earlier ones; missing values (ie, sea plus Antarctica) are -999. The (legacy) format is integer only, so most variables are x10, that is, you must divide by 10 to get actuals. The exceptions are the two day counts, WET and FRS: these are x100, so you must divide by 100 to get actuals. |
