New software package for archival of synoptic And upper air meteorological data

Abstract

The functions of a software package of 6 programmes developed for retrieving, decoding quality control and formatting of surface and upper air coded data have been presented here in brief. Intelligent use has been made of Fortran- 77 fact1ltles to make these programmes extremely efficient. Global data for surface and upper air received on GTS for an entire day is sorted, decoded & formatted after quality control in about three and a half minutes (CPU time) on VAX 8810 system.

The programmes do the management of files and can also be used for decoding the monthly data files of hard copy data. For coding of data, FGGE code has been used with very minor modifications. The results of quality control checks and number of reports received hour wise for each synoptic hour for each WMO block are monitored. Information from both is displayed on the terminal in tabular form and also recorded in disk for monthly archival.
