DataGURU is a service to disseminate spatio-temporal data to colleagues in your field and in other fields. Its aim is to ease the access to data that you decided to be freely available, by allowing the user to define the extent, resolution and format in which the user will get the data.

You are eligible to add your data if:

• your data is a geo-located raster (shapefile functionality may be added if required)
• it is of potential use to others
• you own the rights to your data
• you have the required meta-data (location, time, resolution, format, etc.)

The decision whether your data will be made available is ultimately made by the DataGURU team. The data stays your intellectual property and you remain responsible for providing correct data.

How it works

DataGURU allows the data owner to enter the meta-data of the dataset to be disseminated. At a user's request, the server downloads the data and performs the required conversions to deliver it in the requested form. DataGURU stores the meta-data in its own database.

Where your data is stored

• Your own web space: provide a link to your web page or FTP server; the data is downloaded on request. This lets you keep updating your data, but you must ensure long-term availability.
• DataGURU-hosted storage: if you don't have your own hosting, we can store the data — on our server, or for very large datasets, at a suitable location we help you find.

Account & login

To submit a dataset (or download existing ones) you need a DataGURU account. Sign in via magic link (email) or Google. Once logged in, the login icon is replaced by account management and logout icons.

Submitting a new dataset

Go to Manage Account → My datasets → Add a new dataset to open the meta-data editor. Hover over each field for inline help text.

• Title — the name of your dataset.
• Description — a short, fully searchable description. Include a project name or publication tag here (e.g. LehstenGEB2014) so others can find your data by searching for it.
• Organization, email, DOI, Reference URL — contact and publication details for the dataset.
• Spatial extent — western, northern, southern and eastern limits in latitude/longitude.
• Temporal extent — start and end dates in year-month-day format.
• Temporal resolution — one of 3hour, 6hour, 1day, 1month, 1year, 10year. If your data uses a different resolution, leave this field blank and describe it in the comments field instead.
• Public URL — the root path containing all variables (an FTP folder or web address).
• Private URL — used only if DataGURU is hosting your data and it's organized across multiple folders (e.g. one per year).
• Naming convention — describes how files are named, using the pattern {rel_path}_{year?}{month?}{day}.nc. For example, WFDEI rainfall data named Rainf_daily_WFD_CRU_190104.nc would be written as {Rainf}_daily_WFD_CRU_{year}{month}.nc. If unsure, describe the convention in the comments field and the DataGURU team will check it.

After filling in the fields and pressing Submit, a pop-up lets you add any further details not covered above — for example geographical projection info, or a note asking DataGURU to host the data for you.
