Short summary
We present seven years of cloud water measurements from the summit of Whiteface Mountain in upstate New York to evaluate how organic acids affect cloud droplet acidity in the summer. Sources of these acids, ranging from local biogenic emissions to long-range wildfire smoke plumes, play a major role in reshaping the cloud chemistry of this remote region, which was once controlled mainly by industrial pollution.
