摘要

In Antarctic ice sheet, firn compaction corrections should be applied to the elevation changes estimated from multi-year satellite altimetry to reduce components without mass change contribution. Firn compaction rate is mainly affected by firn temperature and density in the vertical column during the yearly and decadal scale compaction processes and it's essential to account for these two parameters in the firn compaction modelling. In this paper, we solved the temperature along depth and time given initial and boundary conditions based on published physical principles and both our experimental software and an open-source package. We have performed a comparison analysis between the modeled and field temporal temperature profiles at the Taishan Station, East Antarctica. The mean temperature differences of the results with the 12-hour and 1-month time steps are ™0.36 K and ™0.45 K, and the standard deviations are 1.7 K and 3.2 K, respectively. The temperature modelling process is a part of the firn compaction correction estimation modeling.
