MODIS@20 Data System Evolution
Abstract
For almost 20 years, standard products from the MODerate Resolution ImagingSpectrometer (MODIS) instrument on NASA's Earth Observing System's (EOS) Terra satellite have being used world-wide for earth science research and applications. The MODIS data products are produced at a variety of levels and are designed to be ready for analysis. This talk describes the evolution of the MODIS data systems over the last two decades in which the distributed systems that produce, archive and distribute high quality MODIS data products were scaled by several orders of magnitude. Since launch, production, archiving and distribution have all improved significantly, the most notable trend being the large increase in distribution to the external user community. This includes post-processing performed by the distribution system to minimize the additional processing users need to perform after receiving the data. These capabilities have been achieved despite reductions in budget due to improvements in technology as well proactive re-architecting and evolution the data system. Near real-time capabilities have also been developed to support applications requiring the data within a few hours of acquisition. The MODIS data systems have remained agile to serve the community as technology and users' expectations have changed. The goal continues to be to make MODIS data more useful for the scientific and broader user community and to make scientific collaboration easier. Over the last few years, cloud computing technologies, such as object stores and Docker containers, are being deployed to keep these data systems efficient, sustainable and cost effective.
