The WAC global mosaic is comprised of over 15,000 images acquired from December 2009 through January 2011. The WAC maps the whole Moon in one month, however the solar incidence angle at the equator changes about 28 degrees from the beginning to the end of the month. To even out the incidence angle variations, the mosaic is comprised of data collected over three periods (2010-01-20 to 2010-01-28, 2010-05-30 to 2010-06-06, 2010-07-24 to 2010-08-07) (Table 1). Some gores were filled with data taken at other times between 2009-12-10 and 2011-01-31; complete image lists for each 100 m/px tile can be downloaded separately. The non-polar images were map projected onto the GLD100 (WAC derived 100m/pixel DTM) while polar images were map projected on the LOLA shape model (80 to 90 degrees N/S) and the GLD100 (60 to 80 degrees N/S). Accurate positioning of each WAC image was ensured using ephemeris provided by the LOLA and GRAIL team and an improved camera geometry model [1]. To reduce brightness discrepancies across image boundaries, all images were corrected to a common photometric geometry using a Hapke model with model parameters varying across the Moon [2]. This mosaic uses only the 643 nm band of the WAC. The WAC global mosaic is archived in ten regional tiles at three different resolutions: 100 meters/pixel, 256 pixels/degree, and 128 pixels/degree. Eight of the tiles are equirectangular projections that encompass 60 degrees latitude by 90 degrees longitude (for the 128 pixels/degree products, these tiles extend from the equator to the pole). The remaining two tiles are polar stereographic projections for each pole from 60 degrees to the pole. Lower resolution products (at 64, 32, 16, 8, and 4 pixels/degree) are available in single global equirectangular tiles, centered at either 180 or 0 degrees longitude (longitude ranges from 0 to 360 degrees and -180 to 180 degrees, respectively, and latitude range always from -90 to +90 degrees). Additionally, orthographic products are available at all resolutions showing the hemispheres centered at the equator at 0, 60, 120, 180, 240, and 300 degrees longitude, and the polar tiles described above are also available at all resolutions. Each file is named with the following pattern (see Table 1 for examples): WAC_GLOBAL_[E|P]###[N|S]????_***[M|P] where: [E|P] indicates the map projection (E=Equirectangular or P=Polar Stereographic) ###[N|S] indicates the center latitude in 1/10th degrees North (N) or South (S) ???? indicates the center longitude in 1/10th degrees East ***[M|P] indicates the scale in meters/pixel (M) or pixels/degree (P) Low-resolution 8-bit browse products in PNG format for this product, along with full-resolution 8-bit GeoTIFFs, are available at the following location, with names matching those of the full-resolution IMG files: http://lroc.sese.asu.edu/data/LRO-L-LROC-5-RDR-V1.0/LROLRC_2001/EXTRAS/BROWSE/WAC_GLOBAL/ When citing this product, use the following reference, but see [3] for a brief summary of updates made in 2014: Speyerer, E.
