Attempting To Turn Night Into Day; Development Of Visible Like Nighttime Satellite Images, Frederick R. Mosher
Attempting To Turn Night Into Day; Development Of Visible Like Nighttime Satellite Images, Frederick R. Mosher
Applied Aviation Sciences - Daytona Beach
Visible satellite images have long been used in aviation flight planning. The visible satellite images show a variety of phenomena of interest to aviation, including fog, low clouds, thunderstorms, etc. Since one’s eyes detect visible light, the visible satellite image is easier for untrained personnel to interpret than other bands. The biggest problem with the visible images is that they are not available at night. However, other channels on the satellites can be used to develop a derived satellite product which looks very much like a visible satellite image. This derived product can then be inserted into the nighttime portions …

Revisiting 3d Stereo Satellite Image Displays, Frederick R. Mosher
Applied Aviation Sciences - Daytona Beach
Over 30 years ago, there were a number of development efforts to display 3D stereo satellite images and associated weather. Dr. Fritz Hasler showed how the GOES-east and west satellites could be remapped to generate true stereo pairs for obtaining cloud heights and he also showed how artificial stereo images could be generated using derived IR cloud heights to generate parallax shifts for the visible or infrared images. While there was a flurry of interest in the 1980s, the techniques had largely fallen from routine usage until recently. However, technology advances in both satellites and display technology has allowed for …

Applied Aviation Sciences - Daytona Beach
Flight planning and flight following dispatch operations require information on potential flight hazards. Hazards such as thunderstorms, turbulence, icing, fog, volcanic ash, etc., are potential problems which are not always forecast adequately by numerical models. Satellite images are used to monitor the weather conditions causing existing flight hazards, as well as being used to identify the development of new hazards.
Analysis Of Causes Of Icing Conditions Which Contributed To The Crash Of Continental Flight 3407, Frederick R. Mosher, Debbie Schaum, Chris Herbster, Tom Guinn
Analysis Of Causes Of Icing Conditions Which Contributed To The Crash Of Continental Flight 3407, Frederick R. Mosher, Debbie Schaum, Chris Herbster, Tom Guinn

On February 12, 2009, at 10:20 p.m. EST, Continental Connection Flight 3407 from Newark to Buffalo crashed 5 miles short of the runway at Buffalo, killing all 49 people on board and one person on the ground. The National Transportation Safety Board (NTSB) is still investigating the crash, but preliminary reports show the airplane was experiencing icing conditions before the crash. Preliminary reports indicate that the pilot did not respond properly to the icing conditions, which contributed to the crash. However, the presence of the icing conditions which were significant enough to cause aircraft problems needs further investigation to determine …

Global Composite Of Volcanic Ash “Split Window” Geostationary Satellite Images, Frederick R. Mosher
Applied Aviation Sciences - Daytona Beach
Volcanic ash is exceptionally hazardous for jet aircraft in flight. Flying through ash can quickly damage the jet engines, causing surging, flame out and immediate thrust loss. Pilots can inadvertently penetrate volcanic ash clouds because airborne weather radar will not reflect off the small ash particles, and the visual appearance of an ash cloud may look very similar to an ordinary meteorological cloud. To aid pilots in avoiding ash cloud areas, the International Airways Volcano Watch (IAVW) agreements have developed under the guidance of the International Civil Aviation Organization (ICAO).
Day/Night Visible Satellite Images, Frederick R. Mosher
Day/Night Visible Satellite Images, Frederick R. Mosher
Applied Aviation Sciences - Daytona Beach
Visible satellite images are very helpful for a wide variety of users. In particular, they are helpful in identifying areas of clouds and fog for general aviation pilots who must fly within sight of ground. However, visible satellite images have several major drawbacks, such as at night the visible pictures are black. Another problem is that it is sometimes difficult to distinguish between high clouds and low clouds. While the infrared channel can be used at night, frequently the low clouds and fog are near the temperature of the ground, so low clouds do not show up well on infrared …
