| 英文摘要 | Using the recent compilation of the isotopic composition data of surface snow of Antarctic ice sheet, we proposed an improved interpolation method of delta D, which utilizes geographical factors (i.e., latitude and altitude) as the primary predictors and incorporates inverse distance weighting (IDW) technique. The method was applied to a high-resolution digital elevation model (DEM) to produce a grid map of multi-year mean delta D values with 1km spatial resolution for Antarctica. The mean absolute deviation between observed and estimated data in the map is about 5.4 parts per thousand, and the standard deviation is 9 parts per thousand. The resulting delta D pattern resembles well known characteristics such as the depletion of the heavy isotopes with increasing latitude and distance from coast line, but also reveals the complex topographic effects. |
