Speedwell Weather supplies 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.
Our origins as
a weather data provider lie in the weather risk markets where we are the
dominant provider of weather data for used for the pricing and settlement of weather-risk
contracts. 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, to 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 more information.
