THE BLUE HILL METEOROLOGICAL OBSERVATORY OF HARVARD UNIVERSITY founded by Abbott Lawrence Rotch in 1885. Pioneered in upper air studies by means of clouds, kites, and balloons--most recently with radiosondes (first American type developed here 1935). An exceptionally complete, mostly automatic record of the weather has been kept for 65 years. Visible at right of tower are louvred screen for thermometers, radar target, dew-point recorder, and pyrheliometer for diffuse insolation, and at left of tower, top, are several pyrheliometers for total insolation, and atop the masts are various anemometers and wind vanes.
