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.
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, 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

SuperPack TM: Speedwell SuperPack
makes available an unprecedented range of quality historical weather data and
weather data feeds for a single annual fee. The SuperPack licence applies
corporate-wide across multiple office locations
One contract, one fee, covers all data. SuperPack users have
immediate access to a catalogue of over
10,000 data sets - and growing. These data sets are shown on this map tool
here. Use this tool to see
percentage
completeness
statistics, to access data tools such as Actuals-Vs-Climatology and the Weather
Statistics Extractor; and
to download the data directly from the
web site. Subscribers can request an unlimited number of historical
data sets and real-time feeds by FTP.
The list of weather sites available for immediate access grows continuously: In
addition, SuperPack subscribers can also request any data from our secondary
archives of many tens of thousands of weather sites around the world. SuperPack
subscribers also have access to over 5,000 -and growing- cleaned data sets
including official international climate data.
SuperPack-Light.
SuperPack-Light is for sophisticated weather data users, including those
following the agri-markets, who require large volumes of high quality world wide
data but who do not need the full-service provided under the full SuperPack
subscription. SuperPack-Light is a corporate-wide subscription delivering to up
to a maximum of 1,500 user-chosen daily data sets by FTP which can be selected
from over 10,000 data sets...all at zero marginal cost. SuperPack-Light
subscribers also receive access to additional data download from the website and
use of web-delivered tools such as Actuals-Vs-Climatology and the Weather
Statistics Extractor
Cleaned Data Sets:
Weather data is often incomplete and may contain erroneous values. Our Cleaned
Data Sets correct erroneous values and fill missing data. We carry in excess of
5,000 cleaned historical data sets of temperature and rainfall and some other
variables and we clean over 4,000 sites per day. We also provide cleaned hourly
data sets and feeds.
Quality, provenance and auditability: We believe data cleaning is a very
serious business. Our origins as a weather data provider lie in the weather risk
markets where we have acted as settlement agent in hundreds of over-the-counter
weather risk transactions. This represents the sternest test of data quality and
provenance.
- Our cleaning techniques build on a very substantial software, hardware and
human resource infrastructure which builds on a database storing daily and
hourly data for over 80,000 worldwide weather reference sites. Our tools alert
us to improbable values by the use of methods including proxy testing, analysis
of hourly reports and satellite imagery. However, we believe weather data
cleaning can never, and should never,
be fully automated. Our data cleaning processes are always manually overseen by
meteorologists.
- We also understand the importance of data provenance. At Speedwell we
store our data in a strict hierarchy that provides transparency on issues such
as source, reporting convention and quality. While clients can request to
receive our data as a "best-of" feed, we can also provide data showing these
component data types:
Hourly Frequency Reports
We are able to provide hourly frequency reports for any hourly weather variable
and for any period. The most frequently requested product is the hourly
frequency report covering a specific year and shown by month. This shows how
many hours in temperature interval were recorded in each month of that year.
Click
here for an
annotated example. Hourly Frequency Reports can be provided for any variable for
any site for which we carry hourly data. We carry historic hourly data for many
thousands of sites in Europe, Australia, Asia and the Americas.
Hourly Average Temperature Data Sets
("Climatologies")
Many clients approach us to buy hourly data which they use to calculate an
average value for each hour for each day of the year. This is something we can
provide saving the costs of buying and handling large hourly data sets. The
output is a file with 24 *366 data points and can be delivered by FTP or by
email. This can be provided for any variable for any site for which we carry
hourly data. The average can be calculated with or without kernel smoothing. The
average can be based on any period with 10 years being the most requested. We
carry historic hourly data for many thousands of sites in Europe, Australia,
Asia and the Americas. Click
here for more
information
Wind storms: historic data and
real-time feeds. We provide historic data for
European wind storms reports and can provide hourly data updates by FTP to
support verification of insurance claims or for the valuation of CAT-bonds
throughout the year. Weather variables we can supply are hourly maximum gust,
hourly average wind speed, hourly wind direction and hourly surface pressure.
Data is based on both Metar and Synoptic reports. We offer a high density of
sites. Please see
here for more information.
Standard Historical Weather Data
Packs. We have well over 500 different packs of weather data.
These include packs defined by country, by sector (eg China cotton growing
areas) or by weather variable (eg hourly Germany data pack for power market
analysts). See
here to view our data packs on our map
tool. All sites are also available individually.
These are just some of our data packs:
