Photometrically normalized 7-color semi-global mosaic using Hapke parameter maps

Contents: Photometrically normalized radiance factor (I/F)

Wavelength: 321, 360, 415, 566, 604, 643, and 689 nm

Areal Coverage: 70°N-70°S, 0°E- 360°E

Map projection: Equirectangular (centered at 0°N, 0°E; 400 m/pixel at the equator) using ephemeris data provided by Lunar Orbiter Laser Altimeter (LOLA) and Gravity Recovery and Interior Laboratory (GRAIL) teams [1] and an improved geometric camera model [2].

Image Source: ~124,300 images acquired by Wide Angle Camera from January 21, 2010 to May 1st, 2013

Photometric Normalization: Normalized to the angles of phase (g) = incidence (i) = 60°, emission (e) = 0° by Hapke bidirectional reflectance function [3] using Hapke parameter maps [4]. The g, i, and e angles were calculated using the WAC stereo digital terrain model (GLD100) [5]. Each pixel value of this mosaic consists of a median of normalized I/F from ~40 months of repeated observations (UV:58-59, visible:136-140 observations in average). For more methodological details, see [4].

Archive Products: The semi-global 7-band mosaic is archived by each band with tiles of 70° latitude by 90° longitude tiles. All tiled product files are named in following manner: WAC_HAPKE_[wavelength, e.g., 321NM]_[projection, E for equirectangular][center latitude x10][N/S][center longitude x10].
