Abstract

This dataset provides global clear-sky ice surface temperature data derived from infrared satellite measurements, with estimates of the uncertainty components included. It forms part of the collection of datasets from the EUSTACE (EU Surface Temperature for All Corners of Earth) project, which is producing publicly available daily estimates of surface air temperature since 1850 across the globe for the first time by combining surface and satellite data using novel statistical techniques.

The data provided here is Level 2 ice surface temperature data from the AVHRR (Advanced Very High Resolution Radiometer) series of satellite instruments, provided on the original satellite swath. This original AASTI (Arctic and Antarctic Ice Surface Temperatures from thermal infrared satellite sensors ) was produced under the EU NACLIM and the NORMAP projects; This version of the dataset has been extended under the EUSTACE (EU Surface Temperature for All Corners of Earth) project to also include components of uncertainty.

Title Derivation of the EUSTACE/AASTI global clear-sky ice surface temperature data from the AVHRR series on the satellite swath with estimates of uncertainty components
Abstract Global clear-sky ice surface temperature data has been derived from thermal infrared satellite measurements from the AVHRR (Advanced Very High Resolution Radiometer) series. For information on the algorithms used to derive this data see e.g. the EUSTACE scientific user guide (coming soon).
