NASA has launched a new initiative; the Open-Source Initiative (OSSI) to enable and support science towards openness. The OSSI new initiative supports open-source software development and dissemination. This presentation highlights an open-source platform (i.e., NASAaccess) for accessing, reformatting, and presenting quantitative remote sensing earth observation data products. The main objective of developing the NASAaccess platform is to facilitate exploration, modeling and understanding of the data for scientists, stakeholders, and concerned citizens aligning with the new OSSI initiative goals. NASAaccess platform is available with an open-source software packages (i.e., R and python libraries), and an interactive format web-based environmental modeling application for earth observation data. NASAaccess software program is also linked to various downscaled climate change data products processed by NASA. The NASAaccess web application development and hosting environment is based on Tethys Platform (Swain et al., 2016). NASAaccess current capabilities (v.3.3.0) covers various NASA datasets and products that include the Global Precipitation Measurement (GPM) data products, the Global Land Data Assimilation System (GLDAS) land surface states and fluxes, and the NASA Earth Exchange Global Daily Downscaled Projections (NEX-GDDP) CMIP5 & CMIP6 climate change dataset products. NASAaccess installation instructions and documentations along with tutorial materials are available at Open Science Framework repository ‘NASAaccess Home’ (doi:10.17605/OSF.IO/CTJ2K).
