GINA is a mechanism within the University of Alaska (UA) for sharing data and technical capacity among Alaskan, Arctic, and world communities.
Established in 2001 as an initiative of UA’s President, GINA promotes collaboration at the local, state, and federal levels by increasing community-wide participation in the discovery and use of geospatial data. GINA’s products and services greatly expand the range of available analysis capabilities in order to better address research and management requirements.
|No Northern Lights, but Plenty of Southern Shadows|

Today’s total eclipse may have missed Alaska, but weather satellites had a great view. Here is a loop from the new GOES-16 satellite showing the moon’s shadow zipping across the Lower 48.
This imagery is a combination of three channels ranging from visible light into the near infrared spectrum, and these wavelengths all have one thing in common: they respond to sunlight bouncing off of the clouds, land, and ocean. When the moon briefly blocks out the sun, such as during today’s eclipse, these is no sunlight to bounce of the targets below, and thus briefly darkness becomes visible.
GINA works with the satellite proving ground community to bring the newest tools and techniques in satellite meteorology to forecasters working with the National Weather Service and others. You may note that Alaska is not covered in this imagery, as the longitude at which GOES-16 hovers is simply too far east to allow a good look at Alaska. But worry not: GOES-17 will be in orbit within another year or two, and at a longitude far enough west to provide a great view of Alaska (and Hawaii, for that matter). Today’s imagery from GOES-16 offers Alaskans a preview of the improvements yet to come.
This loop, and the website hosting this very nice interface for interrogating all kinds of imagery from the GOES-16 satellite, is maintained by the professionals at the Cooperative Institute for Research in the Atmosphere (CIRA) in Colorado.
GINA receives numerous geospatial data sets, many in real time. Information is then rapidly processed and managed for use by scientiﬁc researchers, state and federal agencies, and the general public.
GINA is involved with many Alaskan, Arctic and International projects. Our goal is to increase community-wide participation in the discovery and sharing of geospatial data.
GINA teams with partner institutions and agencies to create information products and services that are used in a variety of projects to better display and understand spatial information.
