Imageur du ciel
- Yankee Environmental Systems - TSI-440A
The Model 440 Total Sky Imager (TSI-440) is a full color sky camera and software package that offers the forecaster as well as the atmospheric research community an easy-to-use and reliable field sensor for sky imaging.
- Real-time cloud images accessible via a web browser using TCP/IP
- Open architecture uses standard JPEG files
- TSI-Manager image processing application collects data and converts raw images into cloud cover on your workstation
- Color imager uses reliable CCD technology
- Environmentally sealed for long-term field use
The Model TSI-880 automated total sky imager contains an embedded image processing system that automatically processes raw images into percent cloud cover and presents the results via a web interface. Because it does not require a local image processing workstation, the TSI-880 system is truly standalone. Its built-in cooling system also permits higher temperature operation, as well as remote data collection via a Data Storage Module option. The TSI-880 is designed for challenging professional meteorological, aviation and military applications where automated 24x7 reliability is required. However, both the TSI-440 and TSI-880 share the same charge-coupled-device based imagers.
