Imikpuk Lake site on 21 June 2001.
 

A selection of dates shows the temporal evolution of the wavelength-integrated albedo at the Imikpuk Lake site.  The increase in albedo from 18 June to 20 June is due to partial refreezing of surface melt water.  Note the similar shapes of the curves for 18 June and 24 June; it appears that most features were maintained despite the refreezing on the 20th.

The temporal evolution of the Imikpuk Lake site spectral albedo measurements. Data from some wavelength bands have been deleted due to low signal levels.
