Background: The Chinese Academy of Science has designed and manufactured an instrument for making satellite cloud atlas with high resolving power and this is the instrument's automatic tracking antenna.

The instrument receives photographs of cloud layers taken and transmitted by earth satellites.

The present instrument is an improvement of a 1970 model.

The photographs picked up by this new instrument are clearly defines and its resolving power is 8 times higher than the early model.

This is a photograph of the distribution of the claud system of Typhoon No. 3 of 1975 in which the spiralling layers of clouds are clearly visible.

This another typhoon
Chinese meteorologist are using such cloud atlas for analysing weather forecasts.
