Finding climate data at NCI
There are a lot of climate data resources which are available at NCI. Only some of them have been listed in the NCI data catalogue and even then there are a few tips that can help you working out if the dataset you are looking for is already available or not.
Step 1 - check the NCI data catalogue
NCI uses a geonetwork catalogue to list its collections, this covers most of the bigger data collections hosted by NCI. To find a dataset you can run a text search or select from a list of available attributes.
Free text search
Geonetwork free text search will look for an exact match in the record title and description. For example if I am looking for "precipitation" datasets I need to type the entire word, if I type only "precip" it will return only this dataset:
"Proportion of days per month with precip > 0.2mm: ..."
Likewise typing "precipitation" will return 62 datasets including any record that has the exact word in their title or description.
Selection by topic and other attributes
NCI created some categories dividing the datasets based on "topic", they are shown on the catalogue main page. Once you click on one of them you will see a panel on the left side of the screen showing all the available attributes you can use to select datasets. The same is true if you run a text search, you could then refine your selection using this panel. Probably the most useful attributes are the keywords, they are based on keywords set by the data manager themselves or on Field Of Research (FOR) standards.
Unfortunately the selection panel can be a bit obscure, for example often the FOR codes appears as a sequence of numbers rather then their definition for example "0401" rather then "atmospheric science". This is because the dataset descriptions and attributes are provided by the owners of the data, so there is a big variance in what is included and how keywords are chosen or interpreted.
Another limitation is that a dataset might be available as part of a data collection but not having his own record. If the collection is well described then at least you should be able to locate it, sometimes the record descriptions are very generic and don't necessarily list of the datasets included.
NCI is working on an improved and more user-friendly interface and is also working with all the data managers to improve the quality of the records. Feel free to send them feedback or tell us if you prefer and we will pass it on.
Step 2 - check the CMS wiki
The CMS wiki lists all the datasets we download and manage for our researchers. Some of these are also listed in geonetwork, mostly are not because in some cases we have downloaded only a small subset.
Step 3 - ask the helpdesk: email@example.com
If you still can’t locate the datasets you were looking for or you find the dataset but the description wasn’t sufficient to determine that it covers your needs then feel free to e-mail us on the helpdesk.
As both geonetwork and the wiki are potentially incomplete or some of the records might be out of date, it is always a good idea to double check with us. We also might know about other data which is on raijin but not necessarily listed or enquire on your behalf to our partners to help you locate a specific product.
If you still cannot find what you are looking for we can help you downloading the data. When we receive a request to download data we try to get back to you as fast as possible with an answer and a timeframe. We are usually able to download the data for you and put in a shared environment where others can also access it. If the dataset requires a lot of storage, the download is time consuming or needs ongoing maintenance we have to check if it is in the center objectives with the infrastructure committee before going ahead.
It is rare that we have to say no to someone and we don't do it without a fairly strong reason because we prefer to download and manage the dataset for you. Having the data shared in a central location where other can access it too is also a better use of disk storage.

ARCCSS and CLEX datasets and software published on Research Data Australia (RDA)
The Centre of Excellence for Climate System Science has started publishing its datasets on Research Data Australia (RDA), the Australian National Data Service (ANDS) metadata repository. The first datasets to be published were from the Climate Model Downscaling Data for Impacts Research (CliMDDIR), then the ACCESS CMIP5 simulations.
