CliMond Climate Data Frequently Asked Questions

How do I know which version of the CliMond data I am using?
Version control is used for all CliMond data products. The current version is V1.2 and this was released on the 9th September 2014. The original release was V1.0 and this was released on 22nd July 2011. The last component of the file name string, along with the first line of the readme file contains the version number. Updates applied to the data products are detailed here.

I have used CliMond data products in my research, how do I cite them?
In first making reference to the data obtained from the CliMond archive, please include the phrase "the CliMond dataset (Kriticos et al. 2012)". Subsequent references within the same publication might refer to the data with terms such as " CliMond data", "the CliMond multi-model dataset", "the CliMond archive", or the "CliMond dataset". Additional citations to sources of the underlying data may also be appropriate. Please note the following critical references:

Can I download a previous version of the CliMond data?
For efficiency purposes, we only have the current version of the dataset available for download. If you require a previous version, however, please contact us and we will make it available for you.

How does CliMond data compare to the data provided in CLIMEX Version 3?
The CliMond dataset is provided at a spatial resolution of 10' and 30’ compared with the 30' CRU data provided with CLIMEX Version 3.0. The CliMond CM30 dataset is slightly more extensive (67 419 locations) compared with the 30’ CRU dataset (61 076 locations). The temporal coverage is similar (centred on 1975). The CliMond dataset also includes a selection of future climate scenarios.

Why do some minimum temperature values exceed maximum temperature values?
In some of the CliMond V1.0 datasets, a small number of the minimum temperature values exceed the corresponding maximum temperature values for the same month (5 grids in the Netherlands and 1,559 in Greenland in the 10’ data). This issue stems from, and is also a problem in the WorldClim dataset (Version 1.4, release 3). The issue arises from the minimum and maximum temperature variables getting splined separately in the WorldClim climatology. Where the error on the maximum temperature is a little negative, and the error on the minimum temperature is a little positive there can be crossover of the estimates. The problem occurs in cold areas during April and October when the daily temperature range is extremely small. To see where these errors occur and their magnitude please download our summary here.

Using the affected datasets, CLIMEX reports a cautionary error during import of the datasets and during model runs. CLIMEX treats this error condition by assigning the average of the two readings to both the minimum and maximum temperature values. This issue is also present in the Bioclim and Köppen-Geiger datasets, but the user is not alerted to their presence.

In the CliMond V1.1 and above datasets, we have addressed this issue for the relevant grids by replacing both the minimum and maximum temperatures with mean temperature (average of minimum and maximum temperatures). All grids outside these two regions in the Netherlands and Greenland remain unaffected.

My question isn't here and relates more to the ExDet tool or the Bioclim registry
