How to build your order
1. My subscriptions
First, you should log into your Weather DataHub account, or, if you are visiting for the first time, register for a new account. In order to start creating an order, navigate to the ‘My subscriptions’ page. You should land here automatically when you log in.
2. Get started
From the ‘Subscriptions’ page, click the ‘My Orders’ button under ‘Atmospheric’ to begin. There
is no requirement to subscribe in order to do this, but you will not be able to collect data for
the order until you do.
From the ‘My orders’ page, click the ‘New order’ button.
3. Models
Explore our models on the product selection page for descriptions. When you have selected one of our models, simply click ‘Start a new order’.
4. Region
You can view the preset regions in the drop-down menu (availability varies by model). Alternatively, for certain models, customise your area by drawing a bounding box within the map. This defines your region and updates the coordinates below the map. Adjust these coordinates for precision.
Note that the UK model in Lambert Azimuthal Equal Area projection offers limited presets due to bounding box complexity. Many opt for the Equirectangular Latitude-Longitude projection for smoother integration with other models.
5. Single-level parameters
Our single-level parameters are organised into collapsible accordions, grouped by category. To expand your options, simply click the ‘+’ next to a category.
From there, you can choose the parameters you need within each category. For more information visit our glossary page.
6. Multi-level parameters
Our models feature multi-level parameters across different levels:
Pressure (x33)
Height (x34)
Depth (x4)
Cloud base (x2)
To see more parameters, click ‘expand view’, or use the arrows to scroll horizontally. Access all levels by clicking ‘show all’ at the bottom of the checkbox table. We show popular levels initially, but all levels are available for expansion.
7. Time steps
The available time steps vary based on your model choice. Use the frequency and range presets to select your required time steps. For ultimate flexibility, individually select valid time steps, allowing any combination you prefer.
Note that we do not currently consider the variable run lengths for model runs. If your selected time step is available for the model run it will be delivered.
8. Model run times
The options vary per model - you can choose from the run times on offer. To keep you informed we make sure to show you the forecast length for every run. Feel free to select one, several, or all runs according to your needs.
9. File delivery preferences
GRIB2 is flexible as a file format in that it can be split or combined as required. Within specific volume limits, you have the option to determine the level of granularity at which the files will be delivered.
Note that we cannot guarantee a specific preference.
10. Check and confirm order
At the end of the process, you will be presented with a summary of your order. Use this page to
verify the details are correct and make any amendments.
Once you are happy, you will need to press the ‘Confirm’ button at the bottom to activate your
order and make it accessible via our API. Note you will also need an active Atmospheric
subscription to download data.
How to amend your order
An order can only be edited before it has been confirmed.
If an order is in the ‘Incomplete’ state, it means there are required details that still need to be configured for the order. If it is in the ‘Draft’ state, it means the order is valid but has not yet been confirmed, and can therefore still be modified.
To edit an Incomplete or Draft order, click the cog next to the order under the ‘Actions’ column of the orders table. You will see an ‘Edit’ option on the menu that appears. Alternatively, you can click on the name of the order. On the next page, you will have the ability to edit the various parts of your order, as outlined above.
To update an Active order you have already confirmed, you will instead need to copy the order and make adjustments to the new version. To do this, click the cog next to the order under the ‘Actions’ column, and click ‘Copy’.
You will then be asked to confirm you would like to continue copying the order.
A new, Draft copy of the same order will be created, with ‘copy_of_’ prepended to the start of the original name. You can now make the required changes and rename it as necessary.
Once you have finished making your changes, you can cancel the original order. To do this, click the cog next to the order under the ‘Actions’ column, and click ‘Cancel’. Your implementation will need to be updated so it now requests the amended order instead of the old one.
