Speedwell Weather supplies quality historical and real time weather data feeds for tens of thousands of sites across the globe. We have been working in this sector since 1999. Unlike many suppliers who distribute only free, publicly available data, we also have direct data supply agreements with a large range of national meteorological services. This means we are able to offer official Climate Data for many thousands of sites worldwide. We are a single-point of contact for the provision of high quality weather data to the energy, agriculture, commodity, insurance and weather risk markets.
We are the dominant provider of weather data for settlement of weather-risk contracts world-wide
Our origins as a weather data provider lie in the weather risk markets. As a result, we understand the importance of data quality. We quality control data from thousands of sites to correct errors and, where necessary and possible, fill missing values.
Over the years we have come across a lot of bad data! ...as a matter of policy, for
reasons of quality, we do not
deliver data derived from GSOD archives unless specifically requested.
If you see a difference between the data we provide and data sourced from other
sources we will not be surprised. There is a lot of bad data out there!!!!
Please contact us for a detailed explanation of the pitfalls of some commonly
used public archives of weather data. These can be different not just in detail
but FUNDAMENTALLY. Click here for
