    Based on context I'd presume it's a reduction in surface temperature of 0.159C.

    A 1905 book on clouds has been uploaded to Project Gutenberg, the scans of the illustrations are not perfect, but the show quite clearly that clouds back then look like clouds now.

    Cloud Studies by Arthur W. Clayden (1905)


    The authors introduction recommends the book to meteorologists, artists and anyone who is interested in the sky.
