Persistent albedo reduction on southern Icelandic glaciers due to ashfall from the 2010 Eyjafjallajökull eruption
Popis výsledku v původním jazyce
In April and May 2010 the Icelandic volcano Eyjafjallajokull experienced an explosive eruption that led to substantial ashfall across the central-southern parts of the island. The resulting ash deposits covered Eyjafjallajokull, Mýrdalsjokull and parts of Vatnajokull ice caps. In order to quantify the influence of these deposits on albedo, we analyzed albedo evolution across Eyjafjallajokull and Mýrdalsjokull ice caps over the period 2001 to 2016 using the MOD10A1 and MCD43A3 data products of the Moderate Resolution Imaging Spectroradiometer (MODIS) sensor onboard the Terra and Aqua satellites. A geostatistical model with a daily temporal resolution was used to delineate areas on the ice caps that show distinct ash cover related albedo reductions over the post eruption period. Results suggest that despite an overall decrease of the ash cover related albedo reductions with time, noticeable albedo reductions persist on both, Eyjafjallajokull and Mýrdalsjokull over the entire post eruption period.
