Software to access, archive, and disseminate surface weather observations around the United States has been developed continuously over the past 15 years as part of MesoWest (http://mesowest.utah.edu). Data and metadata from ~20,000 active stations from ~100 distinct data streams have been obtained, stored in relational data bases, and disseminated through many different web accessible applications. This software has relied on a mix of shell scripts, perl, MySQL, and various graphical and scientific packages (e.g., Matlab and IDL). Further development within this disparate software environment was becoming increasingly difficult and costly.
A concerted effort has been underway during the past year to migrate core components of the MesoWest software to Python to more efficiently: (1) receive data streams from diverse sources using Python servers; (2) store metadata and data using PyTables and hdf5 storage formats; (3) improve real-time quality control algorithms; and (4) provide access to the metadata and data using a web API and improved graphical tools. Software development with Python was facilitated by a short tutorial course to the MesoWest software team. The speed at which both novice and experienced programmers transitioned legacy codes as well as developed new software using Python was remarkable.
