Validation coordinator - better-satcen-00002 queue - North West Niger Area¶
This coordinator feeds the better-satcen-00002 data pipeline queue with products over a North West Niger Area
- First do the imports of the Python libraries required

- Read the data pipeline configuration information:
In [2]:
%store -r
