Network for Observation of Volcanic and Atmospheric Change (NOVAC): SO2 flux from Nevado del Ruiz Volcano (Colombia)

Emission rate of SO2 from Nevado del Ruiz volcano for the period 2014-01-01 to 2016-09-30. This dataset contains individual SO2 flux measurements obtained from scanning DOAS instruments part of the NOVAC network, operated by SGC/OVSP (Colombia), and daily statistics. Data has been processed with the NOVAC batch processing software, using meteorological data from the ECMWF ERA interim analysis database (0.125/0.125 deg, 6 h) interpolated at the volcano summit coordinates for the time of each measurement. Plume height and direction is obtained by triangulation of two scan measurements when possible. It also includes daily statistics. The file has been prepared within the DECADE/DCO project. Raw data can be accessed by contacting the authors.本数据集收录2014年1月1日至2016年9月30日期间内瓦多·德·鲁伊斯火山（Nevado del Ruiz）的二氧化硫（SO2）排放速率数据。数据集包含由哥伦比亚SGC/OVSP运营的NOVAC网络扫描型差分光学吸收光谱（DOAS）仪器获取的单次二氧化硫通量测量值，以及每日统计结果。所有数据已通过NOVAC批量处理软件完成预处理，处理过程中调用了ECMWF ERA interim再分析数据库的气象数据（空间分辨率0.125°×0.125°，时间分辨率6小时），并将数据插值至对应测量时刻的火山峰顶坐标处。在条件允许的情况下，可通过两次扫描测量的三角定位法获取火山羽流的高度与传输方向。数据集同时包含每日统计信息。本数据集由DECADE/DCO项目团队编制完成，原始数据可通过联系作者获取。
