Synoptic Weather Photography

NSSDCA ID: 1965-043A-02

Mission Name: Gemini 4
Principal Investigator:Mr. Ken Nagler


The synoptic weather photography experiment was designed to provide a set of high-resolution pictures of a broad range of meteorological phenomena, especially views of a number of specific cloud systems of interest to investigators. Because the spacecraft had a 90-min orbit, the experiment could show changes in the same cloud pattern during this interval. A hasselblad 500-c camera with 70-mm ektachrome MS SO-217 film was used. Five magazines, each capable of 55 exposures, were carried on board for this and the other photographic experiments. A haze filter was attached to the standard Zeiss planar 80-mm f/2.8 lens to reduce the intensity of the blue light scattering from the atmosphere. Photographs taken when the spacecraft was in a nearly vertical position cover an area approximately 161 km sq. From oblique angles, larger areas were clearly visible, but there were distortion, resolution loss, and color fidelity loss in the images. Of the two hundred and seven 70-mm color photographs returned for all photographic experiments, approximately 50 percent displayed cloud formations or other information of meteorological interest.
