GHRC staff members are working with the science team from the Hurricane and Severe Storm Sentinel (HS3) Earth Ventures – Suborbital 1 mission to define data and metadata formats and structures conforming to the netCDF (network Common Data Form) / CF (Climate and Forecast) data and metadata standard. For five of the six HS3 instruments, PI-provided sample data files have been augmented as needed for netCDF/CF compliance and returned to the PIs for review.
