AEROSOL CHEMICAL PROCESSES IN THE ENVIRONMENT - CHAPTER 5 pot

... In the semi-acid region of Colorado, the pH is constant at 7.30 in the first part of a storm and drops to 7.00 in the second part. In Italy, the pH oscillated between 6.4 and 5. 6, indicating the ... will also expand the belt of clouds containing ice north in the southern and south in the northern hemisphere. This in turn will increase daytime global cooling. 8...
