User_Note: All of the datasets provided on this website are part of ongoing research projects.Users of the data for research leading to conference-level or peer-reviewed publications should contact Dr. Patrick Minnis (p.minnis@nasa.gov) before publishing any papers that include data from this site. The source of the data should be properly acknowledged and/or co-authorship should be offered depending on the level of documentation and contribution of the particular dataset.If only the satellite imagery are used then we ask only for a simple acknowledgment: \"the images were obtained from the NASA Langley Cloud and Radiation Research Group, http://www-angler.larc.nasa.gov \". For any derived cloud, icing, and radiation products, it is in the best interest of individual researchers who use these datasets to ensure that they are using the latest and highest quality products available. Either Dr. Minnis or other group members can provide the proper references, caveats, or level of participation needed for any given request.
