Automatic Aura Remote Sensing Satellite Data Acquisition System

Aura is one of National Aeronautics and Space Administration (NASA) Earth Observing System (EOS) satellite series. It measures aerosols, ozone, and other gases from space to gain knowledge about the chemistry of our atmosphere. Although it was launched on 15 July 2004, there is still no system available to acquire its data and products specifically for Indonesian region. Scientists usually download the data through Goddard Earth Science (GES) Data and Information Services Center (DISC) or NASA Langley Atmospheric Sciences Data Center manually if they need them. An automatic data acquisition system was established to obtain Aura satellite data in near real-time. The system includes storage management sub system that mimics the data management system in GES DISC. Selenium package in Python programming language was used to program the automatic acquisition through browser crawling and bash shell scripting was used to build the storage management sub system. Analysis of system time in acquiring the data will be done to ensure that the system fulfill the near real-time criteria. Further, analysis of the data volume will also be taken to calculate how many storage that will be required to store the data. In the end, the system will be integrated into low-resolution remote sensing satellite data processing system that is already available in Remote Sensing Technology and Data Center, National Institute of Aeronautics and Space (LAPAN).
