由于目前还没有专门设计的平台，通常使用气象卫星远程监测熔岩流。一般来说，气象卫星的空间分辨率较低，导致结果不确定。本文介绍了对斯特龙博利火山（2014年8月至11月）活动熔岩流的首次长期卫星监测，具有高空间分辨率（160米）和相对较高的时间分辨率（约3天）。这些数据是由德国航空航天中心开发和建造的小型卫星技术实验载体1号（泰特-1）检索的。该卫星仪器专用于高温事件监测。在卫星观测的同时，还利用热成像仪进行了实地观测。这些提供了短时间的熔岩流动力学和验证卫星数据。泰特-1在其喷发活动期间在Stromboli上空检索了27个数据集。使用辐射密度方法，泰特-1数据被用来校准MODVOLC数据和估计时间平均熔岩流出率。在三个月的喷发期间，平均输出速率为0.87 m3/s，我们估计总喷发量为7.4 × 106 m3。
As specifically designed platforms are still unavailable at this point in time, lava flows are usually monitored remotely with the use of meteorological satellites. Generally, meteorological satellites have a low spatial resolution, which leads to uncertain results. This paper presents the first long term satellite monitoring of active lava flows on Stromboli volcano (August–November 2014) at high spatial resolution (160 m) and relatively high temporal resolution (~3 days). These data were retrieved by the small satellite Technology Experiment Carrier-1 (TET-1), which was developed and built by the German Aerospace Center (DLR). The satellite instrument is dedicated to high temperature event monitoring. The satellite observations were accompanied by field observations conducted by thermal cameras. These provided short time lava flow dynamics and validation for satellite data. TET-1 retrieved 27 datasets over Stromboli during its effusive activity. Using the radiant density approach, TET-1 data were used to calibrate the MODVOLC data and estimate the time averaged lava discharge rate. With a mean output rate of 0.87 m3/s during the three-month-long eruption, we estimate the total erupted volume to be 7.4 × 106 m3.
