1. Are UCAR/NCAR images in the public domain?

 No. All University Corporation for Atmospheric Research and National Center for Atmospheric Research images remain the property of UCAR. Access to the images included in the UCAR Digital Image Library is restricted and protected by U.S. copyright laws.

2. How can I get permission to use photos for non-commercial purpose?

You have permission to use all images for non-commercial use. These are available at no cost for all non-commercial users. However, they may not be used to infer or imply UCAR/NCAR endorsement of any product or position or be used for religious or political purposes. Neither should they be used to distort the reality of the image they portray. If you have questions regarding use of any UCAR material please e-mail us.

4. Can I use an image for a commercial purpose?

Images in this library may not be used for commercial purposes without UCAR’s consent and may not be used to infer or imply UCAR/NCAR endorsement of any product. They may be used for educational and nonprofit purposes only. Contact us for further interpretation of this policy.

5. What are Favorites?

The Favorites page is a place where you can store images that you like as you explore the Digital Image Library. To place an image in Favorites, just open it and click on “Save.” Even if you shut down your computer and then restart it, the images will remain in Favorites until you remove them.

6. What file formats does the Digital Image Library include?

Each image comes in two two file formats: JPEG and TIFF.The enlarged JPEGs are about 500 x 800 pixels large  and the high-resolution TIFFs are about 2400x3600 pixels. All JPEGS and TIFFs have embedded metadata with caption information.

7. What are the best uses for JPEG and TIFF file formats?

 The JPEG is lower resolution and can be used on the Web or in a presentation, but it is too small for most print purposes. The TIFF can be used for higher-end print publications (brochures, papers, books, etc).

8. Does UCAR have available images in addition to those in the Digital Image Iibrary?

Yes. These online selections represent only a portion of the material in the UCAR image archives. If you would like one of our photo researchers to investigate a particular area, you may e-mail us. The digitization project is ongoing. We will continue to scan new items, but we only plan to scan the portions of the collection that are of the highest interest.
