April 2011 was a relatively dry month here in Big Sur, with just 0.66″ of rain at my station, ~750 ft in elevation. There were 3 rainfall events sampled for pH. As shown below all three readings are fairly acidic, compared to what one would expect for ‘pristine’ rainwater (~5.6).
It is raining here in Big Sur at the time of this posting (May 15), so I’ll have some May numbers to report before summarizing the 2010-2011 rainy season. For previous seasonal summaries see my posts, Acid rain in Big Sur, and Acid rain in Big Sur – 2009-2010 rain year summary.
