The National Oceanic and Atmospheric Administration (NOAA) Climate Database Modernization Program (CDMP) funds some data rescue efforts within the NOAA line organizations to make climate and environmental data more accessible and easier to use. Data restricted to file cabinets and Warehouse storage are becoming accessible via the World Wide Web. NOAA’s National Geophysical Data Center (NGDC) holds solar imagery back to the 1920s, available on 35 mm microfilm, as well as printed photos and drawings. A CDMP project was funded to scan many solar images to digital format and make them available on the NGDC Website. The scanned daily images document many phases of solar activity, from decadal variation to rotation variation to daily changes. The images include Calcium K, Hydrogen Alpha, and white light photos, as well as sunspot drawings and the comprehensive drawings of a multitude of solar phenomena on one daily map (Fraunhofer maps and Wendelstein drawings). An overview of the project and the current status will be given.
