The dataset is covering the period from 1 Nov 2015 until 16 Dec 2015 (status on 8 Mar 2016).
If you have access to ECMWF systems you can retrieve test data from MARS archive using keywords:
class=mc expver=0067 |
If you don't have access to ECMWF computers but would still like to access a large subset of test data to validate your systems you can use ECMWF WebAPI service.
Read documentation and see brief request syntax of the ECMWF WebAPI service. |
If you haven't done it yet you will need to create an ECMWF web account and accept the data licence.
