Water Abundance is Dependent on Temperature in Deep Impact Maps

Caption

These are deep impact observations of the northern polar regions (~60 km/pixel; June 9, 2009). Left to right: Clementine basemap (with 15° grid) of observed area; Brightness image generated from Deep Impact (at 1.2 µm); Temperature map (in K) derived from >4 µm spectra; Map of the strength of the water signature (continuum-removed 2.8 µm band depth). There are significant variations in the water signature across the lunar surface. While the strength of the water signatures is not correlated with terrain type (bright highland vs. dark maria), but is dependent on temperature.
