Dear All,

We have discovered two errors in our JGR acid deposition paper, so today submitted a correction to JGR, which you can download at:

http://climate.envsci.rutgers.edu/pdf/AcidDepositionCorrectionJGRsubmitted.pdf

The deposition values are actually about 400 times larger than we had stated, but the conclusion that they would not be significantly larger than deposition from other current sources is unchanged. Comments welcome.

It is amazing that this error slipped through all the authors, reviewers, and Editor, and was only pointed out by Maggie Zhou, attempting to reproduce our work. But this is how science works - with a built-in self-correction mechanism. I always had a feeling that the values we previously had in Fig. 3 were too small, and I should have followed up on that feeling. We made the mistake by being careless with units and writing down numbers without units. Let this be a lesson to all of us.
