| description abstract | AbstractThis study presents a new monthly pressure dataset poleward of 60°S, from 1957 to 2016, based on a kriging interpolation from observed pressure anomalies across the Antarctic continent. Overall, the reconstruction performs well when evaluated against ERA-Interim. In comparison to other reanalyses, the reconstruction has interannual variability after 1970 similar to products that span the entire twentieth century and is a marked improvement on the first-generation reanalysis products. The reconstruction also produces weaker pressure trends than the reanalysis products evaluated here, which are consistent with observations. However, the skill of the reconstruction is weaker in the South Pacific and therefore does not improve the understanding of long-term pressure variability and trends in this region, where circulation changes have been key drivers of climate variability in West Antarctica and the Antarctic Peninsula. | |
