The Java based
water vapor animation loop (130 k) has
been big hit during the initial testing.
To support enhanced access to satellite data, NCAR Director Dr. Robert
Serafin allocated funds from the Director's 1995 Equipment and Instrumentation
Fund for the acquisition of a GOES-8 receiving station and commercial software
for processing real-time satellite data. That system is now installed at
NCAR's Foothills Laboratory and is fully up and operating.
A LARGER
reproduction of the same image, with twice the resolution is
shown in the
Image Gallery.
Two versions of a short, seven frame animation loop (130 k, each)
showing this water vapor imagery are also available:
After some weeks of preparation and testing, these satellite
pages are now formally linked to the NCAR and MMM web pages. In
particular, the Satellite Coverage and Orbits
section has undergone a lot of work. Check it out!
Satellite Observations of the Atmosphere

Satellite observations are becoming critical to an increasing number of
atmospheric phenomena. Use of satellite data requires an appreciation for
the satellite's orbital constraints and instrumental limitations. These
pages are intended to provide a general overview of some of the features
of satellite data sets available to NCAR and UCAR scientists, as well as
some tips how to access data.
Information about NCAR's new GOES-8 system
REAL TIME satellite imagery from NCAR's system
These pages are optimized for Netscape 2.0, or later. All the information
should still be there for users using other browsers, but the pages may
not be as pretty. The critical features are background color and Java
support, although other features are used as well.
Featured Image
CAPTION:
This image is an infrared image of the earth in the water vapor
absorption band at 6.7 microns, collected by the GOES-8 geostationary
satellite. In this false color image the darker areas represent
colder temperatures and the lighter areas indicate warmer temperatures.
The pattern reflects the distribution of water vapor and liquid water
in the mid and upper troposphere.
The recommended version of the animation requires Java.
The alternate version of the animation uses a sequantial
display of a multiframe gif file (requires Netscape 2.0 or higher).
Additional Images and Information
Image Gallery
(currently 40 k, but with many optional links) The Image Gallery presents a large (at least it will
be getting large pretty soon)
number of interesting examples of satellite imagery from a variety
of different Projects and satellite systems.
Examples of archived data for STERAO-A
(86 k, but with optional links to large image files)
This link shows some examples of the Colorado area window for which
GOES-8 imagery data is being archived during the current STERAO-A
project.
Recent Imagery Covering Panama
This link presents recent satellite imagery, both visible
and infrared, over Panama. It is intended as a source of background
information for scientists interested in the Proposed STERAO-B program.
How do I get Satellite Data?
A discussion of a variety of data sources, including
NCAR's new GOES-8 system.
Satellite Coverage and Orbits
(86 k) Background information about the limits of coverage
and orbits for Geostationary and Polar Orbiting satellites.
External Links (57 k) Links to a number of other WWW sites that provide
satellite imagery and information.
