SRRL TSI-880 Image Gallery

---

A Yankee Total Sky Imager TSI-880 image is captured every 10-minutes
and archived to the YESDAQ database. The system also produces a "cloud analyzed"
image and computes the percent cloud cover. After a submission is made, both of
these images will presented along with the thin and opaque cloud cover values.
Images available from July 14, 2004 through July 20, 2008

Note: The instrument only analyzes clouds between zenith angles of
0 to 80^o (clouds on the very low horizon are ignored).
