Speedwell carries weather data for over 100,000 sites worldwide. The Speedwell Data Inventory tool presents only the 12,000+ of
the most frequently requested sites. The tool serves two functions: one is to show our core data sets to all viewers, including
those who are not logged in. The other is to provide access to tools and data download for SuperPack® clients. All these data
sets are available to SuperPack® clients for no additional charge directly from this web site or by FTP delivery.
Note that the search function operates only on the 12,000+ sites shown, not our whole inventory. If you cannot find what you need please contact us.
Please note that not all variables are shown for all sites. We can normally
access far more data than is shown in the audit tables. Please contact us.
Wind Max Gust readings are usually only reported when there is strong wind. So
series completeness may therefore appear low.
Data before 01 Jan 1950 is not usually shown or audited. Where the Audit Start
Date is shown as 01 Jan 1950, a longer history is likely to be available.
Snow depth readings are only shown when snow is lying. So snow depth
completeness may therefore appear low.
Search: use this to find sites that meet your completeness requirement
for a chosen period. Please note that this function searches all sites in the
defined Box area for the chosen Pack Source and Pack Type filter. The selection
of specific data packs on the Data Packs tab is not relevant to this search.
