Abstract

Satellite passive-microwave sensors provide a sensitive means of studying ice-sheet surface processes that assists ice-core interpretation and can extend local observations across regional scales. Analysis of special sensor microwave/imager (SSM/I) brightness temperature (T_B) data supports ice-core research in two specific ways. First, the summer hoar complex layers used to date the Holocene portion of the Greenland Ice Sheet Project 2 ice core can be defined temporally and spatially by SSM/I 37-GHz vertically (V) and horizontally (H) polarized _B ratio (V/H) trends. Second, comparison of automatic weather station temperatures to SSM/I 37-GHz V T_B data shows that they are an effective proxy temperature record in this region. Also, the 7_B data can be correlated with proxy temperature trends from stable-isotope-ratio (δ¹⁸O and δD) profiles from snow pits and this allows the assignment of dates to specific snow depths.
