Joseph Smith writes software for the acquisition, quality control, processing, storage and application of meteorological data and metadata. Data are retrieved from Web and FTP sites, Web services or captured from dedicated feeds, and subjected to a variety of isolated and cross-variable tests of validity. They are upscaled to various temporal resolutions and utilized to derive additional parameters, stored in a relational database along with ancillary information, and applied to the continuous mapping of meteorological parameters across large geographical regions. Metadata for reporting stations are collected, sorted and validated to provide an accurate positional reference for the data in space and time.
