The spatial pattern and the trends (1948-1980) of several key climatic parameters show that there has been a reduction of the surface noon temperature, over the S.E. United States. During the same time, and over the same region, there has been an increase of dewpoint, relative humidity, and noon cloud cover. The region overwhich these changes occurred coincides with the region of most significant increase in haziness (aerosol concentration). However, a cause-effect relationship has not been established.
