Transcript for Mountain Skywater, segment 06 of 12
The target area is limited to about half of the San Juans, a high, remote cluster of peaks having few permanent residents. Details of weather are measured at many points. One meter even makes use of a ski lift to measure temperatures up and down a steep slope.
In a mountain home, a housewife takes readings of background nuclei. This instrument determines the concentration of tiny particles, including silver iodide, that nature can use to build snow crystals on.
But most of the data are recorded by over two hundred remote stations spread throughout the San Juans.
To keep project results objective, a completely separate contractor gathers data recordings from the weather stations. In sunshine or snowfall, the information must be picked up and the instruments checked at regular intervals.
