MODIS Images: Lake Erie Ice Break-up and Ice Floe

Figure 1: March 3rd through March 8th 2010 (NexSat Project/Naval Research Laboratory) J. Braun Whew!  Hints at spring may finally be around the corner.  Cold Arctic winter temperatures through most of the beginning of this new year have kept much of the Great Lakes in frozen repair through early March.  However, a hopefull proxy for spring is showing itself in the Continue Reading

GOES-11/MODIS channel differencing for icing hazard

J. Braun and Louis Grasso Figure 1: GOES-11 fog product for 8 UTC 2 March 2010. Identification of liquid water cloud layers that have temperatures below freezing is important for aviation safety. Brightness temperature differencing two channels may be used to identify liquid water cloud layers. Figure 1 (above)shows the channel difference between 3.9 and Continue Reading

GOES-R ABI smoke imagery for the Proving Ground

J. Braun, Louis Grasso and Don Hillger GOES-R ABI will have the ability to produce imagery at 0.47 µm (blue) and at 0.67 µm (red). Although GOES-R will be unable to produce any images at 0.555 µm (green), color imagery can still be generated with certain techniques. These techniques can be tested through the use Continue Reading
