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.

The TSI-440 is designed for longterm field installations and features state-of-the-art camera optics as well as user-serviceable mirror components.

The system captures images into industry-standard JPEG format data files, which are then analyzed for fractional cloud cover. At installations where it can be connected to a TCP/IP network, the system acts as a sky image server to web browsers via the Internet. In many meteorological forecasting applications, the accurate determination of sky conditions is a highly desirable yet rarely attainable goal.

Traditionally, trained human observers have reported sky conditions, resulting in considerable discrepancies from subjectivity in observations. In practice, the use of human observers is not always feasible due to budgetary constraints. The TSI-440 offers reliable real-time sky imaging at a reasonable cost. Once the system is set up, there is very little maintenance other than periodic cleaning of the mirror.

 

Features:

  • 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

 


Also Available


 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.
