Time series of monthly groundwater parameters from 1979 to 2015 monitored at the BLZ hot spring site. The dashed lines indicate linear trends. From top to bottom panels: (a) Radon, (b) Water Temperature WT, (c) Discharge rate DR, (d) Galactic cosmic ray (counts/hour/100) GCR, (e) Atmospheric Pressure AP, (f) Rainfall R. Red line indicates monsoon-related rainfall (June, July, August). Note that the Y-axes are reversed for radon and GCR.
