Sounding Data Continuity

RS92 Data Continuity
​Information about significant changes in the Vaisala Radiosonde RS92 family and the related ground equipment.

Data Continuity from RS92 to RS41
The impact of radiosonde model switch from RS92 to RS41 on climatological time series is estimated to be moderate. The statistical differences between RS92 and RS41 are described in this site by experimental sounding results.

Data Continuity as RS41 is in Operational Use
Vaisala intends to offer the best possible tools for climate research, including accurate measurement instruments with carefully estimated uncertainty budgets, as well as tools and the metadata for managing data continuation. At this site Vaisala commits to announcing all RS41 product changes that could affect the homogeneity of climatological data series.
