Big Sur rainfall and pH data have been tabulated for January 2010 and the numbers are as follows:
I’m noticing that when the storms are particularly windy the rainfall pH seems to be higher (less acidic) than other rainstorms with less wind. I don’t have any data to verify this, but it’s something I plan to pay more attention to in the future. Could this be due to all the particles blown off the surrounding trees? Or from sea spray? Dunno.
