Read pm10_conc data

Hi, thanks for this great node module.

Could you tell me if it's possible and how can I get all the JSON of the pm10_conc variable ? I'm working on data air pollution.

It looks like this :

There is 3 parameters to get the value :

Latitude.
Longitude.
Time.

If I use `reader.getDataVariable('pm10_conc')` I'll just get the result of the first cell.

I can send you my .nc file by email if you want.
