The data available through the Web API is organized in Datasets has its own availability. If you go to
http://apps.ecmwf.int/datasets/
You will view can discover all the ECMWF Public Datasets that are available from our archive. We strongly recommend you to to navigate through our public datasets archive to become familiar with the their availability of our archive. You may select a Public Dataset and start navigate navigating trough the contents.
| Note |
|---|
Some of the Datasets available are not completePlease take into account some considerations about the content: - Different Datasets include different "parameters" , "times", and "steps"
- In each Datasets not all the "parameters" are available from all "steps"
- In each Datasets not all the "steps" are available from all "times"
|
The web -application interface above will help you to check and understand the availability. For any kind of selections the system will update the attributes in a dynamic way to reflect the current availability. (ie i.e. if you change the steps some parameters will be added or removed).

|
| We encourage users to use the "View MARS request" feature at the bottom of the page once the selection has been done. Using this MARS request you can build your own Python script. See If you are interested on the syntax go to Brief request syntax. |
For instanceExample of usage:
- If you click on the interim Dataset ERA-interim http://apps.ecmwf.int/datasets/data/interim_full_daily/ you will get a web page reflecting the availability of this specific Public Dataset as the period that this specific Dataset it is available, the forecast steps and the parameters that are available etc.
- From this page you have the option to define the attributes values of your requests such as the "date", the "time" the "steps" and the "parameters" that you are interested in.
- In the case of the interim Dataset ERA-Interim if you select time "06:00:00" only, the system updates the availability of the "steps" dynamically. In that case only the "step" 00 is available (ie checkable).
- Additionally Additionally if you select "step" 00 you will see that only a subset of the parameters are now available and only these parameters can now be checked.
Spend some time to understand how it works, make some selections try to execute the MARS scripts.
