Abstract. Using data assimilation (DA) to improve model forecast accuracy is a powerful approach that requires available observations. Infrared satellite measurements of volcanic ash mass loadings are often used as input observations for the assimilation scheme. However, because these primary satellite-retrieved data are often two-dimensional (2-D) and the ash plume is usually vertically located in a narrow band, directly assimilating the 2-D ash mass loadings in a three-dimensional (3-D) volcanic ash model (with an integral observational operator) can usually introduce large artificial/spurious vertical correlations.In this study, we look at an approach to avoid the artificial vertical correlations by not involving the integral operator. By integrating available data of ash mass loadings and cloud top heights, as well as data-based assumptions on thickness, we propose a satellite observational operator (SOO) that translates satellite-retrieved 2-D volcanic ash mass loadings to 3-D concentrations. The 3-D SOO makes the analysis step of assimilation comparable in the 3-D model space.Ensemble-based DA is used to assimilate the extracted measurements of ash concentrations. The results show that satellite DA with SOO can improve the estimate of volcanic ash state and the forecast. Comparison with both satellite-retrieved data and aircraft in situ measurements shows that the effective duration of the improved volcanic ash forecasts for the distal part of the Eyjafjallajökull volcano is about 6 h.

Post Disaster

Indonesia is one of the very prone countries to disaster. The tsunami and earthquake disasters caused enormous damage to property and infrastructure as well as loss of life. An earthquake on September 30, 2009, measuring 7.9 on the Richter scale struck the west coast of Sumatra, causing loss of life and damage to infrastructure. There were around 1,115 people killed, 1,214 seriously injured and 1,688 people lightly injured. A comprehensive study of natural disaster management activities or systems should be used as learning materials to form a disaster management system. Disaster preparedness by minimizing vulnerability has been identified as a better approach to dealing with disasters than post-disaster response. Creating a culture of prevention is critical to dealing with everyday hazards and the consequences of disasters. The study is using data from a natural disaster in west Sumatra, and data from people who were involved in the process of reconstruction post disasters in west Sumatra. This study aims to obtain an accurate description of the reconstruction post-disaster and relation with responsive gender activities in West Sumatra, and identify how the gender effect on reconstruction post-disaster in the West Sumatra region.
