ASC200 Automatic Cloud Cover Observation Instrument
The ASC200 is part of Yunnengtian's ASC all-sky cloud observation instrument family and is also described in published sources as an all-sky imager or all-sky camera. Upgraded from the discontinued ASC100 with an infrared module, it provides visible, infrared and combined cloud cover for all-weather observation.
Features
- Uses image restoration to reduce the effect of solar glare and overexposure on cloud cover observation.
- Uses infrared imaging to obtain wide-field all-sky infrared cloud imagery.
- Includes an embedded shutter-type sun shield to reduce direct-sun effects on the sensor.
- Includes onboard image-processing hardware and does not require an external computer or workstation.
- Low-power design with water, dust and condensation protection.
Applications
- Automated cloud cover observation for meteorological and climate operations
- Solar production forecasting and photovoltaic performance assessment
- Meteorological science, remote sensing and solar resource research
- Cloud cover observation for aviation and marine meteorology

Frequently Asked Questions
What is an automatic cloud cover observation instrument?
It is a meteorological instrument that automatically captures and analyses sky cloud cover. The ASC200 provides visible, infrared and combined cloud cover.
Which indicators does the ASC200 observe?
The ASC200 observes visible cloud cover, infrared cloud cover and combined cloud cover at a stated 10-minute sampling interval.
Does the ASC200 support all-weather observation?
Yes. The ASC200 adds an infrared observation module and combines it with visible observation for all-weather cloud cover monitoring.
How can ASC200 data be accessed?
The ASC200 supports TCP/IP, FTP, Ethernet and serial communication, with browser or app operation.
