User Registration for Dobson Software (WINDOBSON)


WINDOBSON is a unique software package for operation, data analysis and quality assurance of Dobson spectrophotometer observations (total ozone and Umkehr ozone measurements). The package was developed by JMA's Aerological Observatory based on its long experience of operational use of Dobson instruments.


The worldwide community of ozone observation initially pointed out the effectiveness and usefulness of WINDOBSON. The GAW Scientific Advisory Group (SAG) for Ozone identified it as a potential basis for a standardized approach to operation, quality assurance and data analysis of Dobson observations. In response to this, WMO proposed to JMA that WINDOBSON be widely used at WMO/GAW ozone observatories around the world. Considering the software's possible contribution to improving the data quality of global ozone observations and enhancing GAW activity overall, JMA accepted this proposal in March 2006.
