Read Me for the dataset CRU CL v1.1, Reversion of CLD Climatology 1. Introduction Version 1.1 of CRU CL was introduced in April 2022. Its construction, and the reason for it, is described in 'Technical_note_CRU_CL_v1.1.pdf', which should be in the same directory as this file. 2. CLD Climatology The construction of the v1.1 CLD climatology used the same process as the other v1.1 variables. However, it became clear that it was, unlike the others, not an improvement. We are therefore replacing the v1.1 CLD climatology with the original, v1.0 climatology. We apologise for the inconvenience. 3. Related information The erroneous v1.1 CLD climatology has been deprecated and removed; it is, of course, available on request. As always, please adress any questions or comments to i.harris@uea.ac.uk.
