Project aim: to confront the complex obstacles associated with our current inability to trace value-added improvements back to individual ICOADS observations, specifically through: (a) establishment of a database management system to support development of value-added records and facilitate user access; (b) implementation of supporting modifications to the International Maritime Meteorological Archive (IMMA) format; and (c) to scientifically demonstrate the impact of value-added records on air-sea flux estimates and common climate indicator series. |
