Description

1. Technical field

[0001] The invention relates to a part of a ground meteorological observation instrument in the technical field of atmospheric detection, especially an important part of a cloud measuring instrument. 2. Background technology

[0002] According to the requirements of technical specifications, the observation content of clouds on the ground mainly includes cloud base height, cloud amount and cloud shape. At present, the observation instruments for cloud base height mainly include laser nephelographs, cloud curtain lights, etc., and the cloud amount observation instruments mainly include visible light all-sky cameras, etc.

[0003] Calibration is not required when measuring cloud heights with laser ceilometers and cloud curtain lights, usually in the direction of the zenith, and a pitch servo mechanism can also be used to measure cloud heights in different zenith angles. The all-sky camera mainly uses a fisheye lens or a spherical mirror to take pictures of ...
