Daily Summary for 23 February 2007

The low from yesterday moved well off to the east today, taking the clouds with it. Flow from the N - NNE triggered some lake effect clouds over southern Lake Huron, but there wasn't enough moisture to produce snow. The rest of southern Ontario was clear.

Below is a cloud height product from NRL using MODIS data which nicely distinguishes the low clouds from the snow.

C3VP made the decision to not fly the overnight CARE overpass, but instead fly the afternoon London, ON overpass. London is in a prime location for pollution as it is surrounded by many of the Great Lake's most significant polluting cities. This was an ideal CALIPSO/lidar validation flight, but not an ideal scenario for CLEX. CLEX did not participate.

Images are taken every four hours beginning at 0045 UTC.
