JHU/APL AVHRR Dynamic Window for Southeastern United States

Listed in NASA Earthdata CMR

Description

The JHU/APL AVHRR Dynamic Window for Southeastern United States data sets are available via the World Wide Web at: "fermi.jhuapl.edu/dynatrack/us_se/index.html" The following information was abstracted from the description of the web site: "fermi.jhuapl.edu/dynatrack/key.html" Description of the JHU/APL AVHRR Dynamic Tracking Windows Web Site This web site presents images of hurricanes or other areas of interest by displaying a viewing window centered on a target position.

Any given region within our coverage area may be scanned by up to 4 satellite passes (we currently collect data from NOAA-12, NOAA-14, and NOAA-15). The web page is updated automatically around the clock shortly after a pass is completed. The images are highly compressed JPEG so some loss of quality is visible but downloading time is minimized.

The NOAA AVHRR data used to make these images has 5 channels. For daylight passes channel 2, near infrared, is used. Channel 4, thermal infrared, is used when it is too dark for channel 2.

Channel 4 images show cold clouds as dark and warm water as bright. The images are geographically registered. Fine tuning of this registration is called image navigation and is done automatically for these images.

Sometimes for various reasons the images are not registered so well. Close inspection may show some misregistration between the plotted coastlines and the real coastlines in the image. The coordinates labeled on the sides of the image correspond to the plotted coastlines so allowances must be made for any errors in registration.

For storm track plots and higher quality images see the JHU/APL Hurricane Track Map web site ("meto.umd.edu/~stevenb/hurr"). Web page by: Ray Sterner "fermi.jhuapl.edu/res"
