Help/Information
Imagery Information
Imagery derived from the Hurricane Satellite (HURSAT) dataset developed and maintained by the National Climatic Data Center (NCDC).
ISCCP-B1 data provides 3-hr infrared and visible imagery since 1978.
AVHRR data provides infrared and visible imagery since 1981.
SSMI data provides microwave imagery (primarily 37 and 85 GHz) since 1988.
Graphical Browsing
Six hourly storm tracks icons are colorized by the mean intensity based on IBTrACS.
Icons are clickable and pull up a table with links to all HURSAT imagery available for that 6-hour time period with text shaded by satellite type: HURSAT-B1, HURSAT-AVHRR , and HURSAT-MW(Microwave). Italicized font denotes geostationary imagery with less desirable views (higher zenith angles)
Folder Browsing
Imagery can also be browsed by selecting folders in the Places menu (left panel).
Satellite Imagery - Used to select imagery of a specific type. Useful for viewing image loops.
IBTrACS storm path - Toggle the storm path white line
Imagery Chronologically - View all imagery in a 6-hr period (same as clicking an icon)
Storm Icons - Toggle viewing the storm icons
NCDC & NOAA Logos can be toggled on/off
Scales/legends for all imagery can be selected
Viewing loops
1. Expanding the Satellite Imagery folder
2. Check-mark one of the satellite sensor folders (AVHRR-IR Loop, B1-VIS Loop, etc.)
3. The time bar in the upper left can be used to control both the timing and the speed of the loop
Looping Issues
Google Earth loads imagery slowly while looping. To speed it up, do the following:
1. Pull the drag icon in the time bar all the way to the left
2. Pull the left portion of the drag icon all the way to the right (see below). This should make all imagery visible.
3. When all imagery has loaded, pull the icons back together.
4. Click the play button to loop.
5. Animation options are available by the wrench icon.
Caveat
Google Earth's initial position for some storms that cross the Dateline errantly places the initial view on the Prime Meridian. In these cases, the user will need to rotate the globe to the dateline to view the imagery.
